Engaging this autopilot for quality assurance especially helps unexperienced operators.
Both data acquisition settings (e.g. measurement position, illumination settings, camera parameters) and evaluation parameters (e.g. post-processing steps, visualization possibilities, export options) are saved as "recipes". The measurement results are evaluated and tolerances are checked completely. Conduct pass-fail analysis for each parameter. The software comes with extensive export functions allowing to export sample specific parameters with serial number in QS-Stat, PDF and ASCII format.

Xiris systems use high-resolution laser-based 3D imaging system technology and fast data acquisition and analysis rates to enable real-time detection of welding defects up to 0. 015 mm in size.
These systems are used for precise 3D inspection to detect quality problems in forming and welding processes in pipe and profile rolling mills.
The production of welded pipes and lines requires the monitoring of several key parameters to ensure efficient, stable production and to meet quality requirements. Measurement/monitoring is the first step to control these parameters and improve welding quality.
Defects investigated include mismatch, undercut, sunken welds, bead height, deflection, etc.
DIC systems (digital image correlation) can be used very flexibly regardless of the shape, temperature and size of the measuring object and can measure strains in the microstrain range (sub-micrometers) using microscope optics, as well as strain factors of several 100%, or even extreme measurement rates with high-speed cameras. Using the method of digital image correlation (grey value correlation, near-field photogrammetry), they can be used for both 2D and 3D applications. Typical applications from industry and research are motion and deformation analysis, material characterization, component testing and photogrammetric measurements. Measurements include tensile, compressive and bending tests, impact and pressure wave analyses, crack detection, fluid-structure interaction, fatigue analysis and under-surface defect detection.
Polytec offers two 3D DIC systems that complement each other perfectly:
Polytec offers UV systems and components for industrial and research applications in different technologies - from pulsed or continuous LED lights, arc or gas discharge lamps to UV-sensitive industrial cameras.
At Polytec, fiber-optic measuring technology is split into two fields: “fiber-optic sensing technology” and “optical telecommunication / fiber-optic measuring devices”.
Fiber-optic sensor systems use specific optical properties of materials – and often even the fiber itself – to measure physical variables such as temperature, strain or vibration. Extremely flexible solutions can be created in this regard: they range from the single-point measuring system, over individually defined spots along the fiber, to continuously measuring systems with a resolution of 1 mm across optical fibers that run for kilometers. A single fiber weighing just a few grams can therefore contain thousands of sensors and serve as a signal path at the same time. Because light is used as the transmission medium in the glass fiber, applications that remain off-limits to electrical sensor technology – such as in HF and microwave fields, high-voltage environments, potentially explosive atmospheres, chemically aggressive environments and much more besides – are indeed a possibility.
Polytec covers a very wide range of cameras with its portfolio. These include all kinds of industrial applications, as well as research and development.
The wavelength range in this regard extends from UV, over the visible range, to far into the infrared range. Polytec provides you with all the relevant camera systems to complete a wide range of tasks: from simple machine vision sensors to the hyper-spectral camera system for remote sensing, and from the simple line sensor to the high-speed video camera.
The development and advances in semiconductor technology are based on the constant refinement of semiconductor structuring and ongoing improvements to the necessary measuring technology. Thanks to its many years of experience, Polytec is able to provide you with extensive advice in the field of semiconductor and photovoltaic measuring technology.
Decades of experience in consulting and service forms the foundation of Polytec’s expertise in the field of optical infrared radiation measurement technology. Used to qualify and characterize optical and electronic components, the products can be found in research and development, production, quality control and service – either in laboratory or field use. The product spectrum ranges from individual components and sub-systems to complete electro-optical test and simulation systems. These also include testing and simulation tasks in both the visible and the ultraviolet spectral range.
Process analytics is used to optimize the production process, to ensure consistent product quality and, last but not least, to meet environmental requirements. The objective in this regard is to improve product quality and enhance efficiency with a view to reducing costs, saving time and cutting emissions. Automated real-time control allows for controlled interventions to be made even during the product manufacturing process. Costly and time-consuming faulty production operations are prevented as a result.
Process analytics can be used throughout the entire production chain: when inspecting incoming goods, during production (either online in the form of automatic sampling while bypassing process control, or inline in the form of automatic sampling directly during process control) and during final product control.
As they are easy to use and robust, spectroscopic methods – particularly near-infrared (NIR) spectroscopy based on dispersive diode array technology – are a popular choice in this area of application.
The available measured variables are diverse in this regard:
The Multiplexer solution allows the user to perform spectrometer-based measurements with several and even different probes at various points during the process. This means that different evaluation solutions can be used at these spots. This instrumentation enables flexible and affordable integration in customized measurement scenarios for a wide range of applications.
