                    • Precitec’s modular welding head YW52 allows the use of optical elements creating line-focus laser spots. Based on different and independent optical magnifications of the fiber end in x and y direction, almost any rectangular or oval focal spot sizes are realizable. Adjustable optical elements allow to optimize the focal spot quality on site and the process parameters can be adapted. These optics can be used for laser ablation with pulsed laser. An additional application is laser cladding where defined track widths can be achieved by simple means.

                      • operating status can be monitored by PC
                    • ScanTracker

                    • ScanTracker is the number one choice for difficult welding tasks under changing conditions, particular for body-in-white work. The weld quality often hinges on energy input per unit length and how this energy is laterally distributed. Deficient gap bridging with undercuts on butt or fillet welds is often caused by inadequate spot size and inappropriate lateral intensity distribution. With ScanTracker, the programmable scanner mirror ensures exactly the right spot size and a seam width that matches the joint thanks to a high-frequency pendulum motion. An additional unit also controls the laser power, which is freely-programmable, in synch with the pendulum motion.

                      Benfeits:

                      • large gaps compensated by changing the spot width
                      • freely selectable and configurable scan frequency

                    • CoaxPrinter - Your 3D metal printing head

                    • The processing head CoaxPrinter allows completely direction-independent laser cladding with wire. Based on the unique ring-shaped beam shape and the coaxial feeding of the additional filler material, the wire is fused homogeneously from all directions and well connected with the local melt pool. In comparison to the laser cladding with powder, a very high material efficiency is possible since the additional material is introduced and processed at 100%.

                      The homogenous energy distribution in the fully circular focus enables a large process window, which results in a stable process, even if the working distance fluctuates in a certain range. This proves advantageous particularly for the construction of free-formed 2.5D structures. The CoaxPrinter allows wide ranging fields of application, such as the repair of high-quality components, the coating in subject of ware resistance and the generation of thin-walled 2.5D structures or high-volume superstructures. The processing head has interfaces for water-cooling, Cross-Jet and collision protection for the wire feeding. All usual laser types can be used

                      • WeldMaster platform

                      • The WeldMaster systems for the real-time process control and quality monitoring of laser seams are based on one standardized platform, which is responsible for data processing and operator guidance. Camera systems and sensors for measuring and controlling the laser joining process can be connected and evaluated to suit the application concerned. The operator concept is always the same, no matter whether the system is supposed to detect and control the joining position, whether an image is evaluated for detecting welding seam defects or whether only a simple sensor signal, the laser power for instance, is to be depicted. The WeldMaster platform reads all measured data in real-time, evaluates it and, as a centralized system, is able to link data values of various measurement sources in any combination and generate variables or make OK or not OK decisions therefrom.

                        Benefits:

                        • universal platform with standardized operator concept
                        • various operator levels with customer-specific releases
                        • application-specific signal processing can be implemented

                        • graphic editing functions
                        • worldwide remote access
                        • visualization of finishing processes
                      • WeldMaster Track

                      • The WeldMaster Track function measures the position of the components to be joined and of the joint itself. The camera with illumination unit detects the precise joining position of the parts and transmits the data to the WeldMaster platform. This platform calculates the current position values and sends control signals to the translation axes of the welding head position controlled and at the right point in time. The system is able to detect various joining geometries, butt joints for example, even with zero gap, fillet weld in a lap joint, or T-joint. Various camera configurations can be selected, depending on the application.

                        Benefits:

                        • high-precision position detection and control
                        • gap measurement
                        • gap-dependent filler wire control
                        • control of two internal or external axes in a lateral and spacer direction
                        • field illumination for zero gap

                        • all standard joining geometries can be evaluated
                      • WeldMaster Track coaxial

                      • The coaxial configuration is displayed when space in the process area of the laser welding machine is restricted and the joining position has to be measured just a few millimeters in front of the TCP. The Precitec YW52 or YW30 welding head has a beam splitter with optics and camera flange for the WeldMaster Track camera. Images are captured by the welding optics. The illumination, in the form of a laser profile line, is located on a bracket to save space. This configuration is especially suitable for radial and axial seams on round parts, e.g. gear wheels, coupling parts and differential gear wheels. The welding optics are usually mounted on axes designed specifically for fine positioning.

                        Benefits:

                        • minimal space requirement
                        • high-precision position detection and control gap measurement
                        • gap-dependent filler wire control
                        • control of two internal or external axes in a lateral and spacer direction
                        • field bus and analog interfaces for controlling external axes
                        • all standard joining geometries can be evaluated
                      • WeldMaster Track off-axis

                      • The so-called Scheimpflug or off-axis configuration is beneficial with robot applications or machines for welding large-scale components. The camera is integrated along the illumination unit into a dedicated housing, which is mounted to the welding head or to the machine frame in the process area. There are three different Scheimpflug cameras to choose from, depending on the standoff distance and resolution required. As a rule, axes designed specifically for fine positioning control the welding head, the control signal of the WeldMaster Track system delivers the time-critical signals for this process. The Scheimpflug configuration allows the camera system to have a very large working range towards the profile line and produces a better image quality than the coaxial configuration. The WD55 LED camera can be used to detect a zero gap. The standoff distance on this camera is correspondingly smaller and must be kept constant.

                        Benefits:

                        • high-precision position detection and control
                        • gap measurement with zero gap detection
                        • gap-dependent filler wire control
                        • control of two internal or external axes in a lateral and spacer direction
                        • field illumination for zero gap
                        • field bus and analog interfaces for controlling external axes
                        • all standard joining geometries can be evaluated

                      • WeldMaster Scan&Track

                      • ScanTracker is the number one choice for difficult welding tasks under changing conditions, particular for body-in-white work. The YW52 welding head with integrated beam oscillator (Scan) coupled to the WeldMaster System (Track) in the coaxial configuration fulfills all process control and monitoring requirements.

                        ScanTracker measures the joining position in a lateral and spacer direction. Instead of an external axis, the integrated scanner mirror precisely controls the focal position along the measured joint. Additionally, the mechanically-controlled collimation lens compensates any change in the standoff distance. If, for example, the gap width or height changes as well as the position of the joint, the WeldMaster system in addition can overlay a high-frequency pendulum motion to the scanner mirror and thus increase the seam width. The WeldMaster also controls the laser power, which is freely-programmable, in synch with the pendulum motion.

                        The minimum lead times for the measurement, less than tenths of a second, and the application-adapted lateral and longitudinal energy distribution leave nothing to be desired when it comes to optimal process control.

                        Benefits:

                        • high-precision position detection and lateral control
                        • integrated tracking of the focal position if the standoff distance changes
                        • gap measurement and compensation with beam width control
                        • freely programmable, synchronous control of the laser power
                      • WeldMaster Inspect

                      • The WeldMaster Inspect function measures and assesses the welding seam against specified quality criteria. Depending on setup, the camera with illumination unit detects the seam profile and optionally replicates the weld surface together with the surrounding joining parts at a high resolution. The WeldMaster platform processes the incoming image data, calculates profile and quality characteristics and compares them with the specified threshold values. The system sends any flaws detected to be displayed on the GUI, to predefined machine interfaces or to a repair station.

                        Benefits:

                        • detection of the smallest welding errors
                        • application-optimized illumination and image capture
                        • recording of profile and surface data
                        • all standard seam geometries can be evaluated
                        • combined Track&Inspect function
                        • visualization of finishing processes
                      • WeldMaster Inspect 3D

                      • The WeldMaster Inspect function for profile measurements can have either a coaxial or off-axis configuration. The off-axis configuration (Scheimpflug) allows the camera system to have a very large working range towards the profile line and produces a better image quality than the coaxial configuration. The same camera modules as for WeldMaster Track are used. The camera sends the predefined image areas to the WeldMaster platform for evaluation of the profile data, including undercuts, excess weld metal, edge notches. The illumination, in the form of a laser profile line, is located on a bracket on the welding head or integrated into the offset camera housing to save space.

                        Benefits:

                        • all standard joining geometries can be evaluated
                        • can be combined with Tracking function
                        • measurements simply adapted to the application
                        • board range of cameras
                        • customer-specific interfaces

                      • WeldMaster Inspect 2D/3D

                      • The WeldMaster Inspect 3D (profile measurement) can be upgraded by a function for inspecting the surface of the welding bead. In addition to the profile line, the WD55 LED camera is equipped with a freely-configurable LED flash light, and delivers images with seam profile and surface data. Corresponding filters in the evaluation software look for the tiniest pores and irregularities in the seam, evaluating the seam profile at the same time. Comprehensive quality monitoring of the welding seam is thereby guaranteed.

                        Benefits:

                        • detection of the tiniest pores and incomplete fusion
                        • simultaneous measurement of the weld profile

                                      • Flatbed cutting or 2D cutting is the most widely used application in laser cutting. Portal machines are equipped with two positioning axes and on Z axis for the compensation of various distances between the work piece and cutting head. They machine flat material of various gauges from steel, stainless steel, aluminum or non-ferrous metal with large dynamics and high cutting speeds. Thereby, common CO2 lasers, as well as fiber-guided solid-state lasers are used. Precitec offers custom solutions for the cutting head and distance sensors for various machining concepts. From the simplest processing head for manual loaded systems to full-equipped with motorized focus position adjustment, monitoring and process sensor system is available for every suitable cutting head specification.
                                          • Cutting mild steel with CO2 laser

                                          • Flame cutting of mild steel with larger sheet metal gauge is a classic application for CO2 lasers. Cutting 25-30 mm mild steel is included in the performance spectrum of a flexible flatbed cutting machine. The HP 1.5″ and HP2″ cutting heads have been used for this application for many years.
                                          • Dynamic cutting of dynamo sheet metal

                                          • The ProCutter shows its advantage with thin dynamo sheet metal or magnetic sheet metal: The head is resistant to high acceleration and jerk values and thus saves cycle time. The flexible machining of various forms and variable batch sized with high-productivity are the decisive advantages over conventional die cutting.
                                          • Cutting mild steel with solid-state lasers

                                          • The solid-state laser achieves good cutting quality when fusion cutting a material gauge of 12 mm. Flame cutting of mild steel with larger material gauges is becoming more popular as well. The additional energy of the exothermal reaction of iron with oxygen makes it possible to separate greater material gauges. The ProCutter head machines up to 30 mm mild steel with good quality during industrial production.
                                        • 3D Applications

                                        • Either 5 axes systems or robots are used for more complex work piece geometries. Fiber-guided lasers are used in most cases with robot systems. The insufficient path accuracy of robots and partial and positioned tolerances often require the axes systems integrated in the cutting head. These control the distance from the work piece or simulating small forms with high precision. Cutting systems are often a component of entire production lines with difficult environmental conditions. The operators place great demand on interference resistance and maintenance-friendly cutting heads. Custom solutions with cutting heads with internal or external axis systems and communication interfaces are available for 3D applications.
                                            • Laser cutting of auto body components and profiles

                                            • Automotive manufacturers use hot-worked heavy duty steels in auto body production that are difficult to machine with conventional methods. Cut outs on IHU components are often only assembled later due to the process. Today, robot guided laser cutting is the flexible and high-production method for machining high-strength auto body components and profiles. The robot-guided, highly dynamic laser head makes openings and trims e.g. B-pillars at up to 20 m/min. without tool wear.
                                            • Greatest possible flexibility with highest precision

                                            • In case of insufficient robot track accuracy, the FormCutter is the right solution. The system includes a cutting head with an additional z-/y-axis-system. This makes the path programming easier and increases the cuttings precision. Especially in the automotive industries where multiple different types of holes e.g. antenna holes are cut out very late in the manufacturing process the system allows a technology exchange such as from rigid punching to flexible laser cutting.
                                          • Pipe Cutting

                                          • Rotation and horizontal positioning is implemented via work piece movement when laser cutting pipes and profiles. Additional machine axes move the laser cutting head upward via a Z feeder and if need be, at an angle via additional tipping axes. Fast distance measuring directly controls the Z axis and ensures that there is an absolutely constant distance between the nozzle and work piece with complex profile forms at any pipe position. In addition to CO2 lasers, multiple fiber-guided solid-state lasers are used as well that provide a higher cutting speed with approx. 6 mm and can also machine light alloy and non-ferrous metal. Automated pipe cutting requires various cutting head configurations with motorized focus position adjustment and sensor supported monitoring and control functions that match the productivity and layout of the installation.
                                                • Cutting nonferrous metals

                                                • Nonferrous metal can hardly be cut with CO2 due to its high reflectivity in the remote infrared spectrum range. The ProCutter with fiber laser can cut it easily. It is protected against stray back reflections. In addition, nonferrous metal absorbs the laser wavelengths of the fiber laser better, which makes the machining process more technically and economically interesting.
                                            • Micro machining

                                            • Very stable mechanical and thermal machining concepts with precision axes are used in micro machining. Precision in micrometer range with die clearance starting at 10 micrometers are state of the art technology today. Typical applications are cutting filigree structures like stents for the medical industry or cutting the smallest components out of stainless steel, nonferrous metal and ceramic for the watch industry and precision engineering. The cutting heads have to be just as suitable for constant cutting operation with solid-state lasers as it is for various frequency multiplied laser wave lengths in the ultra-short pulse range. The smallest spot diameters require a diffraction limited optical design with the finest adjustment options and respective optical positioning aids with integrated camera technology.
                                                • FineCutter - Finest contours and smooth cutting surfaces

                                                • The FineCutter with integrated camera monitoring can be used for high-precision applications with laser power up to 500 W. Die clearances of approx. 10 µm are feasible with the respective beam quality. Medical implants like stents or other precision parts made up of pipes are cut with the FineCutter. Surgical needles or endoscope parts and micro machining parts for e.g. mechanical watches are additional application examples.
                                                • The journey to the center of the earth - using the laser in a different way

                                                • At the Bavarian Geoinstitut in Bayreuth, the FineCutter is used for basic research. Two diamonds are stretched across from each other via a centering ring in a structure here. There is space for a gel between the two diamonds, in which various clean ore are inserted. Now, the laser beam is focused directly on the clean ore through the diamonds and this is heated up intensely. An internal temperature of over 700° C is generated. By pressing the diamonds together from both sides, the internal pressure increases up to 250 GPa. Material changes can be observed with the aid of a camera monitoring. This structure provides a simulation of processes in the Earth's core. Diamonds can even be produced through the insertion of carbon compounds.
                                              • Process Monitoring

                                              • Sensor technology is becoming more and more important in around the clock production in automated systems. Today, the user wants to be able to simply produce in three-shifts without personnel to monitor the system. Sensor technology for process monitoring and control provides adherence to the parameters and cutting qualities specified. Various sensors provide the necessary security for automated processes in highly-productive systems; starting with an absolutely drift-free distance, safety glass soiling detection, monitoring the plunging process to cutting process monitoring.
                                                  • Monitoring the cutting process in solid-state laser systems

                                                  • Adjusted to the cutting process with fiber-guided solid-state lasers, the Laser Cutting Monitor LCM measures the reflected process and laser beam. Signals can be evaluated customer-side on the piercing process, cutting tear, plasma build-up or back reflection laser beam. The sensor module is optionally integrated into the angled HPSSL cutting head.
                                                  • Detecting of cut interruption in time

                                                  • There is a risk that the cut interruptions when the process parameter deviates at higher cutting speeds and/or material strengths. The process adapter detects cutting interruptions just in time. Stopping the machine and/or repeat function can prevent subsequent damages and rejects.
                                                  • Monitoring the cutting process

                                                  • The cut quality is at risk if plasma builds in the die clearance. The process adapter detects plasma building in time and sends a command to stop the machine. The rejection of parts can be avoided by e.g. reducing the cutting feeder.
                                                  • Lens monitoring

                                                  • A high-quality sensor system monitors the state of the CO2 lenses that are pressurized with high cutting gas pressure. It detects and reports errors that occur to the machine controls and provides immediate shut down of the laser and the cutting gas supply. Expensive rejects or consequential damage can thus be prevented, e.g. the effort to clean and readjust the beam path after a lens break. The monitoring systems have already successfully proven themselves in over 5000 systems.

                                                    • Laser Welding

                                                    • Machining heads for industry applications as well as suitable clamping technology and edge preparation are the keys to success. The welding head not only focuses the laser beam on the correct spot size, but it also measures, if necessary, the joint position right before the process and adjusts the laser spot into the correct position. Online monitoring of the welding process and if necessary, downstream seam check always guarantees a good result. Precitec provides everything from one source - finely adjusted to you application.
                                                        • Impeccable welding seams in thick-walled aluminium

                                                        • When laser welding aluminium, the weld pool is quite distinctly fluid. Material expulsions and holes can occur, and these permit neither an acceptable weld quality nor good bonding.


                                                          Visibly good results can be achieved using a coaxial seam tracking system and the precisely adjustable effective width of the laser spot. Consequently, it is not only thin components - generally the case with conduction welding - that can be welded. The use of the ScanTracker also permits conduction welding, with scan function, of thick-walled aluminium components. There is no need for expensive and complex post-treatment, above fall for visible seams.
                                                        • Individual seam geometries

                                                        • When housing and metal sheet structures from aluminium, steel, stainless steel and NF alloys are welded, the exterior welding seams are so-called visible seams. They should not have a raised form, and ought to fit into the component contour, in other words create flowing transitions.


                                                          Owing to the three-dimensional component geometry and the robot-controlled plant concept, seam tracking is unrelenting. Consequently, deviations in the component position are noticeable and can be compensated by a continuous position correction. The variably adjustable spot size makes the welding seam precisely as wide as the application requires.
                                                        • Precise welding of small contours

                                                        • Gambrel sticks, so-called ISOFIX latch serve for attaching children's car seats. Welding small contours takes place on a stationary welding station with a programmable X/Y axis system integrated into the processing head. This separates the small contours with high path accuracy. Process monitoring also controls the safety-relevant parts to 100% on line. 1.5 million latches are produced in a double work station annually.
                                                        • Optimized performance welding of auto body connections

                                                        • Welding of auto body components places great demands on processing quality. Precitec coaxial process monitoring is used by the innovation alliance Green Carbody Technologies, in order to ensure continuous process monitoring. Thereby, the laser power is also adjusted to the processing time, in order to attain the best possible quality.
                                                        • Welding of backrests with the YW52

                                                        • Laser beam welding is used often in the joining process for the metallic structure assembly of auto seats. Thereby, the individual pieces are connected to each other via a large number of step seams. Moreover, seat components are normally processed with multiple welding heads simultaneously, in order to maintain a lower cycle time.
                                                        • Welding of rear axle drive with filler wire

                                                        • Due to metallurgic conditions, today rear axle drives are often welded with laser and filler wire. Thereby, the seam quality and the seam position is decisive for th connection strength. The seam inspection system SOUVIS® measures both the position of the joint as well as the position and quality of the welding seam in one work cycle.
                                                        • Brazing seam inspection of trunk lids and roofs

                                                        • Brazing seams are susceptible to pores, which can be critical in the outer layer area of the auto body. The robot guided seam inspection system SOUVIS® easily detects the smallest pores to 0.2 mm, reliably and with very low false detection rates. The fully automatically control of brazing seams on roofs and trunk lids is state of the art today and applied worldwide.
                                                        • Roof seam welding with seam position control

                                                        • The joining area is setup here in such a manner that the welding seam is located in narrow grooves on both sides of the roof, the so-called roof channels. The side roof flanges are connected to the side components via laser edge welding in these. The laser beam is positioned on the edge of the roof sheet metal in such a way that it melts evenly into the bottom plate. The seam guidance system LPF provides precise laser beam guidance of the entire length of the seam along the edge.
                                                        • Tailored blanks laser welded

                                                        • When welding tailored blanks, process reliability and thus fully-automated seam inspection is a must. The following forming process bonds the laser welding seam similar to that of the base material. Often, multiple systems are used for seam inspection. Process optimization takes place with the laser welding monitor LWM, seam inspection for geometry and local welding failures with the SOUVIS® system.
                                                        • Follow complex curves

                                                        • Part and stamping variation is often a fact of life. Rather than refurbishing or replacing every die and stamping machine in order to achieve exacting part repeatability, it is often easier to add a seam finding method to the assembly process. The ScanTracker, a welding head that integrates a real-time closed-loop seam-finding process, is an ideal choice for its speed, precision, and repeatability. Even on blind welds on the edge of a car door, the ScanTracker is able to follow complex curves and place the weld right where it is needed, every time.
                                                        • Welding depth monitoring with airbag detonator cap

                                                        • When welding airbag detonator caps, monitoring of the welding depth is of great importance: On the one hand, one is not allowed to weld through it, because the detonator cap is filled with an explosive detonating substance. On the other hand, it must me welded at a depth that is enough to ensure that the detonator cap is sealed. The welding depth on airbag detonator caps has been monitored by the Laser Welding Monitor LWM for several automotive suppliers since 1999.
                                                        • Laser welding with double coupling

                                                        • When welding double couplings, a solid connection is the decisive criterium. Since, welding is done with small focal diameters, it must be ensured that the laser beam hits the joint exactly. This task is conducted by a high-precision seam position control. In order to ensure smooth production, laser power as well as the protective glass slot in the welding head is monitored online.
                                                        • Welding of security-relevant components

                                                        • Constant quality monitoring and documentation is required when welding security-relevant components. Thus, the in-process monitor LWM (Laser Welding Monitor) is used when welding seat slide adjuster and backrests. The LWM sensor unit can be adapted as both standard optic and scanner optic.
                                                        • Monitoring of the seam position when welding powertrains

                                                        • The detection of the joining position is often a challenge for seam guides when laser welding gear wheels. Only the correct positioning of the laser spot ensures a smooth welding connection. The space-saving solution of the coaxial structure of the seam guide can be easily integrated into the welding machine. The sensor measures the position of the radial and axial joints precisely and it can be reproduced, even with small radii.
                                                      • Laser Cladding

                                                      • At laser deposition welding with powder, the laser heats the work piece and melts it locally. Simultaneously, an inert gas is mixed with the fine metal powder is added to the process. Operating area supply with the metal/gas mixture takes place via off-axial or coaxial nozzles. The metal powder melts on the heated spot and binds with the work piece metal. The process is applied everywhere expensive components have to be sealed and repaired. In addition to forming tools, engine components and turbine components like blades are considered the most well-known repair parts. The procedure is used with the build up of function layers, like wear protection layer.
                                                          • Process small batches economically

                                                          • With brake discs for racing wheels, it is especially advantageous to avoid the thermal warpage with very limited heat input locally. The finely structured, sensitive functional areas are 3D laser hardened.

                                                          • In the steel industry milling factories, various milling from 0.5 meter to 2 meter lengths is necessary. As the worlds largest steel manufacturer, Tata Steel depends on laser cladding. The wear-resistant cladding extends the service life from just 8 days up to this point in shift operations to more than tenfold that.
                                                          • Axes for the lumbar industry

                                                          • The heavy-duty cutting of this axe blade for the lumbar industry have been strengthened locally from wear thanks to new hardnesses and wear-proof function claddings. This drastically saves costs, because repairs are only limited to damaged or used areas. The claddings that are applied with the laser are optionally 0.1 mm and 1.5 mm thick, the width can be adjusted between 1 mm and 5 mm. Thicker coats require applying multiple layers on top of one another.

                                                            • Specially developed CHRocodile sensors based on interferometrical and chromatic measuring procedure with the smallest measuring point. Regardless of solar glass or wafers, they precisely measure the gauge and surface structure all the way to the edge. The determination of form parameters, the topography of the contact finger, the simultaneous measurement of gauge and sawing grooves or gauge measurement in real time during the etching process - these are all measuring tasks that are easily completed. Their solid and simple design enables simple integration directly into the production process.
                                                                • Solar cell wafers inline contact-free measurement

                                                                • Highest production quality at high cycle rates - the modular CHRocodile MI5 optical sensor is for this. Because flexible configuration options provide parallel determination of parameters like gauge and surface structure in the production process of solar wafers. It i sin the position to measure wafers and solar cells precisely inline, contact-free and from one side. The sensor can be easily integrated into the production process. It can even be used to measure chemical etching in acid or brine. The edge area of the wafer can be determined through the small measuring space of just a few micrometers. The measuring data is provided in real time by sensors with up to 4 kHz.
                                                                • Finger height on solar cells

                                                                • Cost pressure is now determining the competition in the production of solar cells more than ever, while demands on quality are increasing along side it. For example, the measurement of finger heights and the geometry of conducting paths present the deciding measure for avoiding rejections and the reliability of product quality.
                                                                  The CHRocodile SE optic sensor is the ideal tool, thanks to its high dynamics, for topographically measuring various reflecting surface of the conducting paths in a precise manner - direct in the production process, but also under laboratory conditions.
                                                                  Three dimensional presentations of measuring results in connection with data export of various interfaces provide an exact picture of the quality of the production process and thus, allows for immediate correction of process parameters.
                                                              • Glass Industry

                                                              • Regardless of red, green, cold, hot the sensors of the CHRocodile family measure the thickness and topography of glass of any color or surface structure. Application areas are extremely multifaceted here. CHRocodile sensors have become the industry standard in wall strength measurement of glass containers in inspection machines, gauge measurement of display glass and pipe glass. Even circular deviations of bottles, the wall strength of hot quartz pipes or function foil in pre-fabricated sandwiched layers can be easily determined. The sensor does not even get too hot at glass temperatures of 1,700 °C.
                                                                    • Contact-free wall gauge measurement of container glass

                                                                    • With the production of container glass, high speed during contact-free measurement of wall strength and roundness are especially important. The CHRocodile M4 sensor, with it s up to four integrated measuring heads, can deliver 4000 measurements/second in different positions on the test sample. Even non-round articles are measured thanks to the high performance of the non-wearing measuring head. Since the spot size is only a few hundredths of a millimeter in diameter, even the smallest failure is discovered in the glass. Additional calibration is not required. The sensors ensure high-quality and solid measurements inline on hot and cold ends, in the laboratory and offline mode thanks to the highest precision. The CHRocodile M4 is the standard in the glass industry.
                                                                • Semiconductor Industry

                                                                • Applications in the semiconductor industry require a lateral resolution in the micrometer range and high-resolution in the sub-micrometer range. The sensors measure the gauge of wafers, determine semiconductor structures in screen manufacturing, check bonding during inline quality control. Moreover, they measure transparent coatings, determine paint thickness and monitor mechanical and chemical removal process in real time for quality control. CHRocodile sensors measure reliably in both acid baths and ultra-high vacuum.
                                                                    • Non-contact measurement of wafers

                                                                    • A very simple and also highly precise distance and layer gauge measurement of wafers and solar cells is provided by the sensors from the CHRocodile IT product family. These optical sensors are capable of measuring silicium up to a gauge of 1 mm with just one measuring head. The exact determination of gauge all the way into the edge area is very important for the highest quality. CHRocodile IT guarantees this via an especially small measuring point. But the sensors of the CHRocodile IT family can do even more: Measuring of GaAs wafers, visually non-transparent foils and multi-shift systems. Their solid and simple design enables integration directly into the production process. Naturally, the devices also provide affordable and highly-precise layer gauge measurement in the laboratory.
                                                                    • Gauge measurement of high-doped wafers

                                                                    • Rejection is expensive. Therefore, the form and gauge measurement of wafers must take place with great precision. The CHRocodile DW has proven itself the best in this application, especially with high-doped wafers. It is in the position to measure high-doped silicium very exactly to a gauge of 500 µm with just one measuring head. The solid and simple design of the sensor enables integration directly into the production process. The standard interfaces offered provide feedback in the production line, in order to prevent possible rejections in the earliest stage possible.
                                                                    • Quality assurance measurements in the manufacturing process of semiconductors

                                                                    • Many manufacturing processes are dealing with the removal of layers. For example, during wet etching, solid material is converted into liquid compounds with help of a chemical solution. To check the process optical sensors are used. Sensors are used as well to check rinsing processes that allow contaminants to be removed from the wafer surface.
                                                                    • Encapsulation of chips with dispensing machines (dam and fill procedure)

                                                                    • With procedures called dam and fill, first of all a dam made of a viscous cast compound is set up on the circuit board that completely surrounds the chip. Then a dispensing machine dispenses a material to the inner area of the dam that has a low as possible viscosity. This surrounds the delicate structures and wires completely until the component is completely covered. Precitec chromatic confocal sensors measure the height of these chip cast compound dams without touching them accurately to within a few microns. This ensures that the dam height is sufficient for the subsequent cast of the inner area and the protective paint does not run over unprotected areas. The speed of the measuring procedure enables a 100% check of all components manufactured. As a result, casting components is also suitable for high volume, fully automatic manufacturing.
                                                                    • Measuring glue beads

                                                                    • In the case of glue beads, they often still rely on a visual inspection. It is important that the glue bead trail is continuous and constant. Several parameters are used as quality criteria that can be determined by optical measuring systems. The glue bead must run in the middle with regard to other structures. Undesirable accumulations of material at the start and end point of the bead can be detected. Even gaps can be detected.
                                                                    • Circuit board layer thicknesses

                                                                    • The layer thicknesses of silicon casting compounds or solder resist can be measured. Basically there are two different measuring procedures here, chromatic measuring and interferometric measuring. Silicon casting compound can be measured both chromatically and interferometrically. The layer thickness of coloured solder resist can also be measured with the interferometric measuring method. Here the interferometric method has slight advantages over chromatic measuring because it can tolerate a measuring distance deviation of a few millimeters. A 3D measuring device is required if necessary to adjust the measuring distance so that the measured surface is within the permissible operating range of the measuring head
                                                                    • Through Silicon Via (TSV)

                                                                    • Through Silicon Via is a mainly vertical electrical metal connection by a wafer. Here a vertical pile of thinned out individual chips is connected through using small copper structures. After the etching process these protrude a little above the silicon and are known as bumps. The TSV structures before filling – which are holes with a high aspect ratio – and the bumps that occur after filling can themselves be measured with Precitec sensors. The height of the bumps over the silicon structures and the depth of the TSVs are required

                                                                    • Metallic OLED display masks can be measured with the line sensor CHRocodile CLS. Imperfections can be reliably detected here. The sensors are also suitable for the ever more compact LED chip packages for high levels of illumination and small form factors, such as is common for LED background lighting and LC screens. Both cutting profiles and also topographies can be created. When the chips are assembled, Precitec Optronik sensors determine the correct position of chips.

                                                                      Often individual LED are no longer used but highly integrated chips with a large number of light diodes. When testing these optical chips, contact-free measuring distance sensors are already used to a large extent today. These can measure the height of the LED (Z co-ordinates).

Other quality criteria are bowing and warping that are taken into account particularly with very thin wafers. The structures applied in layers can distort wafers. The level of distortion can be determined very accurately with distance sensors.

                                                                  • The optical sensors of the CHRocodile series makes non-contact and high-precision distance and layer gauge measurement of medical components possible. For example, the exact wall strength of medical balloons is of great importance for the success of the therapy. It is even important to be as precise as possible when processing eye glasses glass and contact lenses. CHRocodile sensors measure glass thickness and the thickness of the anti-scratch coating on the glasses. In the area of packaging, the high-quality requirements for foils, blister, molds and violens are monitored with our precision measuring technology. The sensors been proven useful in many other areas of medical application, e.g. for high-precision measurement of artificial hip and knee joints as well as stints.
                                                                      • Wall strength measurement of balloons

                                                                      • Balloons that are used in cardiology for dilation of constrictions in coronary blood vessels have to be able to handle great demands on their wall strength. The CHRocodile E sensor is the right choice for this precise measurement. It provides contact-free and reliable high-quality measuring data of the lining and taper area of the balloon.
                                                                        High measuring rate, processing of up to 3 encoder signals and the compact measuring head design predestines the sensor for integration in the inspection machines for use in both laboratories and production.
                                                                      • Wall strength measurement of medical packaging

                                                                      • Medical packaging like medicine bottles, syringes or blister packaging have to meet the highest demands. The wall strength of the material used is often an important quality criteria. The chromatic confocal CHRocodile M4 sensor perfect for easily, quickly and precisely measuring this. It determines the wall strength reliably and precisely, even colored packaging like somewhat dark brown glass bottles. Due to its advanced design, the sensor can be implemented into existing production environments quickly and easily and offline measurements in the laboratory are one of its strength as well.
                                                                      • Wall thickness of hoses for medical applications, coatings

                                                                      • The wall thickness of transparent hoses for medical applications can be measured well with interferometric measuring methods. It depends on the individual case whether the thickness of individual layers of multi-layer hoses can also be measured. This may depend on the difference in the refractive indices of the individual materials. If the refractive indices of the materials differ sufficiently from each other several individual layer thicknesses can be measured. The thickness can also be determined for materials which are not transparent to white light– e.g. coloured hoses. In this case measurements are taken with infrared light. In the field of medicine, the thickness of ventricular pump membranes is also measured with chromatic confocal sensors. Optical contact-free measuring systems are also used for measuring the wall thickness of balloons which are used in angioplasty. Up till now, wall thicknesses have been measured mechanically using a micrometer through two wall thicknesses and then the result halved. These procedures are, therefore, only accurate within certain limits. Stent coatings can be measured interferometrically.
                                                                      • Measuring liquid layers and liquid levels

                                                                      • In medical engineering, the oil thickness on hoses of injection needles or venous catheters is important. The thickness of the oil layer can thus be determined using contact-free optical measuring systems. This layer thickness can be determined within a few microns. Should the objects not be evenly moistened, the places with or without oil can be detected. This technique has also been proven when pipetting microtiters. If these are filled automatically, a confocal sensor can measure the distance between the sensor and the liquid surface in another also automated step. The fill quantities for larger runs can be very quickly calculated from this measurement.
                                                                      • Measuring the wall thickness of glass flasks with low wall thicknesses

                                                                      • Glass capillaries are thin glass tubes with an internal diameter of approx. 0.1 - 1 mm. Because of the low internal diameter, capillary forces are created which cause liquids, such as blood for example, to be sucked up. Injection flasks are small glass flasks with a capacity of a few milliliters. They are closed by an injection plug or a penetrable membrane.

                                                                        The wall thickness of these thin tubes or glass flasks can be measured very accurately and, most importantly very quickly, with contact-free optical measuring methods that make it possible for them to be used in inline measuring systems.

                                                                        Here Precitec Optronic interferometric sensors are often used. The wall thickness can be measured within a few microns. The lateral resolution is in a single figure μ range. Topographies can be determined very quickly with a line sensor like the CHRocodile CLS which enables the depth and width of cracks in the glass surface to be measured, for example.
                                                                      • Contact-free 3D measuring systems for endoprostheses

                                                                      • The complex, multi-curved geometries of endoprostheses have tolerances between a few microns up to several hundred microns. Their highly reflective surfaces pose considerable problems for optical measuring systems. The surfaces of the material pairs must be produced in the required quality. Here ultra high molecular polyethylene and metals or ceramic on the other side are used. If parts with these sizes are to be measured in 3D, you need sensors that can record the very different surfaces without losing accuracy. The high apertures of chromatic confocal optical probes ensure that sufficient light from the highly reflective free form surfaces reaches the sensor. Retrieval analysis is an important area of activity as well as quality assurance in production. These analyses are mainly used to understand why wear occurs. Using prostheses that have recently failed in use and have not reached their estimated service life, they try to find the causes.
                                                                    • Plastic

                                                                    • Regardless of the strength of preforms or PET bottles, the foil gauge should be precisely determined during manufacturing as well as packaging - you are in a good place with CHRocodile sensors. Deviations in the production process are recognized by non-contact and fast measurement. The high measuring speed makes it possible to use controls during production. Our sensors have been proven in topography measurement of injection molds, wall strength measurement of blisters (PET, PP, EVOH) with well-known manufacturers.
                                                                        • Topography measurements on injection mold parts

                                                                        • Injection mold parts can vary in nature - whether it concerns form, color or surface condition. A topography measuring system has to get on well with these basic condition, should it provide values that make sense. The CHRocodile SE in connection with optical measuring heads with higher apertures fulfill these requirements perfectly. It can be applied to all surfaces, suitable for almost all component geometries and not sensitive to environmental influences. The measuring precision and lateral resolution are in the µm range, axial resolution in the sub µm range. The CHRocodile SE delivers impressive measuring rates of several kHz via this! But of what use are these impressive values without the possibility of simple integration in the process environment? Even that is taken care of, because sychronization with external hardware is guaranteed by a number of interfaces according to current industry standards.
                                                                        • Thickness measurements of foils

                                                                        • Thin transparent and non-transparent films are typically produced at high speeds, under demanding conditions. Because of this, a more robust sensor must be utilized to determine the film thickness during production. The measurement technique can not be affected by environmental parameters such as temperature, humidity, or vibration of the film. The CHRocodile K, with its interferometric measurement method, meets these conditions perfectly - all while combining the highest precision and speed. This allows the process parameters of film production to be controlled with minimal latency.
                                                                        • Non-destructive measuring of plastic welded seams

                                                                        • Welded seams in plastics must often undergo non-destructive tests. This may be the case in medical applications, such as multi-chamber pouches. Also the connection between the pouch and hoses and connectors can also be joined with welded seams. Quality and reproducibility can also be tested by the thickness of the welded seam.
                                                                        • Measuring air gaps and film thicknesses in production processes of technical polymers and PET

                                                                        • Technical polymers, such as Cyclo-Olefin-Copolymers (COC), are amorphous and therefore transparent, unlike partially crystalline polyolefins. As a result, they are particularly suitable for unilateral, contact-free thickness measurements by optical sensors. Low twin refraction properties are important for optical applications. Outstanding biocompatibility and extremely low water absorption/ water vapour permeability must be emphasised in the field of medicine and diagnostics. COC products are optical window films for flat screens as well as syringes, microtitre plates, cuvettes and flasks. In production, Precitec sensors measure the thickness of air gaps and layer thicknesses.

                                                                          CHRocodile sensors are also used in coating processes by polymethyl methacrylate (PMMA, acrylic glass or Plexiglas). They can also be used in inline processes (roll to roll) to measure layer thicknesses (in the low micron range) on Polyethylenterephthalat (PET), unlike sensors with a low sampling frequency.
                                                                        • Inline wall thickness measurement of artificial casings

                                                                        • The product to be measured is an artificial casing made of collagen. This is used as a natural skin for sausages. The material has a rough surface. This is made from a by-product of leather production and is known as a hide fibre sleeve. Here the ability of the measuring system to transfer continuous measurements to the measuring head quickly and therefore to measure strongly vibrating films is impressive. Without this measuring option the measurements must be taken using a much more inaccurate tactile process by determining the weight. This is much slower. The CHRocodile K sensor supplies high quality thickness values with this semi-transparent film that appears uneven and full of fissures according to the measurement results.
                                                                        • Measuring the thickness of plastics or plastic coatings

                                                                        • Polycarbonates are coated to increase scratch resistance or UV resistance, for example. The coating and the material thickness can be measured by optical sensors without the sensors coming into contact with the items. Polycarbonate, a transparent plastic, is often used as an alternative to glass. Compared with brittle glass, polycarbonate is lighter and considerably more shock-resistant. Its negative properties, such as scratch-resistance or UV resistance can be reduced by coatings. For example, polyurethane acrylate layers of a few microns can be measured with the CHRocodile SE sensor.

                                                                          The same also applies to EPDM. This is ethylene proplylene diene monomer rubber (cellular rubber). It is used for various seals, such as O rings for slide ring seals and for hoses, for steam or hot water, because it is highly flexible and has good chemical resistance. A confocal sensor can detect undesirable corrugation in the material.

                                                                        • Multiple layers can be measured by the CHRocodile IT-TW using interferometric thickness measurements with infrared light. This is the case, for example, with multi-layer food packaging films where the adhesive layer thickness is important. Places without adhesive can be detected in this way. In this way the thickness of films that are not transparent to white light can be measured. Even the individual layer thicknesses of multi-layer films can be measured if the refractive index of the materials is different.
                                                                        • Measuring the wall thickness of plastic moulded parts

Wall thicknesses can be determined in this case directly with the optical probe and a spacer on their own if no measuring machine is available.

First, this combination of two measuring principles enables the user to find the correct answer to the specifications of the respective measuring task. The high measuring speed reduces the measuring time of surface topography substantially. Even strongly slanted and polished surfaces are measured exactly. Our well-engineered technology is not only founded on the being the producer of coordinate measuring machines, but we are the leading provider of topographic 3-D systems for measuring layer gauges, roughness or levelness.
                                                                            • Chromatic confocal distance measurement for the highest demands

It is no wonder that leading companies use our sensors like the CHRocodile SE in combination with measuring heads with high apertures. The reasons for this include the universally applicability of the sensors on all surfaces, the great precision, dynamics and high measuring speeds.

In large scale or mass production these components must be measured reliably at high cycle speeds. As the products are also mostly very delicate, optical contact-free measuring systems offer great advantages here. Optical sensors ensure that all parts are perfectly aligned during assembly. For measurement procedures, the parts must not be touched. Precitec sensors are ideally suitable for dynamic, inline measurements. With line sensors a measuring line replaces the traditional measuring point, which considerably speeds up topography measurements.

A line scanner CHRocodile CLS is used to do this. It can supply high resolution topographs very quickly. A chromatic measuring system is available for special applications that is co-ordinated with the measurement of micromechanical watch components. It combines a video system with a chromatic confocal measuring system within one joint optics system. The measuring system guarantees axial resolutions of less than a micron. The video system gives a direct view of the measured structure by the measuring optic.

The cut edges must be completely inspected to see whether they can cope with the subsequent assembly steps. Precitec Optronik optical sensors measure the dimensions and thickness of the screen glass with suitable measuring heads in inline mode. The optical sensor can measure both the warping of the screen glass and also the glass thickness in one pass at the same time. Sensors also measure the shape and depth of pits that are incorporated by grinding, cracks or laser ablation. The pre-stressed glass is later split along a pit.

Applying safety films prevents the glass shattering. The films consist of multi-layer polyester and corresponding adhesive layers that bind the glass splinters if the glass breaks. If the thickness of these adhesive layers fluctuates, delamination may occur. CHRocodile sensors can measure these layer thicknesses.

                                                                                  Contact-free measuring sensors can measure the thickness of adhesive layers on tablet or smart phone screens. The thickness of the glass is a few hundred microns and adhesive layers have thicknesses less than 20 µm. Areas without adhesive can be identified by non-destructive measuring

Application areas are extremely multifaceted here. CHRocodile sensors have become the industry standard in wall strength measurement of glass containers in inspection machines, gauge measurement of display glass and pipe glass.

The sensor does not even get too hot at glass temperatures of 1,700 °C.

                                                                                • The manufacturer of coordinate measuring machines and topography measuring systems place great value on precision, quality and service. It is no wonder that leading companies use our sensors like the CHRocodile SE in combination with measuring heads with high apertures. The reasons for this include the universally applicability of the sensors on all surfaces, the great precision, dynamics and high measuring speeds.

                                                                                • Precision components in automotive technology are, for example, electronically controlled driver assistance systems (DAS) and their steering angle, speed, acceleration and yaw sensors. When assessing the quality of these DAS systems, contact-free optical sensors measure geometries (e.g. the installation depth of ball bearings) in constricted environments or also through narrow openings in the component. Tactile systems have difficulties here, are slower or fail because the measuring points are difficult to reach.
                                                                                • Dashboard – predetermined airbag breaking point

                                                                                • Passenger safety involves inspecting the predetermined breaking point of airbags in the dashboard. The dimensions of these gaps can be determined with a contact-free sensor. This involves determining in a non-destructive way whether the dashboard is sufficiently weakened at this point by these gaps in order to ensure that the airbag works.
                                                                                • 3D form tests of sophisticated automotive components in the manufacturing cycle

                                                                                • Quality assurance of complex assemblies, such as headlight modules or panoramic sunroofs, is challenging because here transparent surfaces alternate with reflective or matt surfaces. Laser-based measuring systems using the triangulation principle have great difficulties with these surfaces, tactile measuring sensors cannot measure on the move and are normally too slow for measuring during manufacture.

                                                                                  Chromatic confocal sensors can measure on the move and also record layer thickness in transparent materials in addition to spacing information. Thus all surfaces that are challenging to measure can be measured without prior preparation. All measuring points to be recorded on vehicle headlights or panoramic sunroofs for quality assurance during manufacture can be taken reliably both by portal systems and also by 6 axle robots because of compact measuring probes.

                                                                                • Automobile headlights today are located in large, transparent headlight housings that are an important design component of the vehicle. They are mainly free form areas which must be manufactured very accurately because clearances in vehicles are considered a quality feature. The contours of headlight housings can be measured very accurately with a line sensor CHRocodile CLS. Even new light units installed in them, which are known as matrix LED or multibeams, can be measured with line sensors.

This always involves a high level of precision with different component sizes and materials. When processing materials the cutting tool can be controlled by Precitec sensors. With laser joints the welding depth, a critical seam property parameter, is checked by a distance measuring device.
                                                                                    • Ultrashort pulse laser control in depanelling machines

                                                                                    • With distance measurements using confocal sensors, parameters that enable the use of ultrashort laser cutting machines in laser-based depanelling can be monitored precisely. Basically, this measuring system is somewhat more reliable than common, laser-based triangulatory procedures in this area of use. Even confocal measuring systems work just as well on surfaces to be encountered here, such as gold, conductor material and solder resist unlike other optical procedures. Even self-reflecting surfaces cannot harm them. Measuring the Z axis is necessary for the cutting process itself: A contact-free confocal height measurement with an accuracy of 4 μm is used to adjust the focus of the ultrashort pulse laser.

If the tool is not right the manufactured parts will always be defective. Precitec Optronic sensors measure surface properties, such as roughness, with the greatest possible accuracy. The measuring heads that operate contact-free can also not be confused with reflective or shiny metallic surfaces. In precision processing, Precitec sensors control laser systems with an accuracy of a few microns. Special measuring systems for the precision industry link chromatic confocal measuring systems with camera systems, as is required in the clock industry.

                                                                                    • Topography measurements are performed significantly faster with the line sensor CHRocodile CLS line sensor. Thus engravings on rollers (the area of the individual engraving points) can be determined in this way. Graphic and three-dimensional patterns on embossing rollers or plates can be inspected.
                                                                                    • Testing grinding tools

                                                                                    • Grinding tools are regularly conditioned when manufacturing gear wheels for gearboxes. This include profiling, sharpening and cleaning processes that can be tested using roughness measurements of truing tools. Roughness measurements of the sides of truing discs can be performed with Precitec Optronik sensors. Tools coated with abrasive grain materials (e.g. quarz, corundum, diamonds) are scanned optically with white light with a chromatic confocal distance sensor without any contact being made. Truing tools are often more expensive to manufacture than traditional grinding tools. Diamond is a grain material because it has the highest wear resistance. The height fluctuations of the truing coatings are recorded by a Precitec Optronik sensor and displayed as a roughness profile.

                                                                                    • Paint layer thicknesses and the differences in thickness of layers on deep-drawn components can be measured with the CHRocodile S /SE sensor. Therefore this is important because after deep drawing the layer thickness of the previous applied paint layer may vary in distorted areas.
