      • OEM spectrometers

      • Avantes has over 20 years of experience in applying spectroscopy and optical sensing technologies to enumerable environments and industries. Our partnership approach to working with Original Equipment Manufacturers (OEMs) is at the core of our success and philosophy as a business.
          • OEM spectrometers: AvaBench Optical Benches

          • AvaSpec optical benches are available with or without one of our electronics boards for integration into customers' systems. Avantes has developed four types of UV/VIS optical benches, especially for OEM customers. The optical benches AvaBench-75-ULS (used in both StarLine and SensLine), AvaBench-75-MN (CompactLine), AvaBench-75-ULSTEC (SensLine), AvaBench-37.5-HS (SensLine) and AvaBench-100-HSC (SensLine) are Czerny-Turner designs with fiber-optic entrance connectors (standard SMA, others possible), collimating focusing mirrors and a diffraction grating. A choice of different gratings with different dispersions and blaze angles enable applications in the 200 to 1160 nm range.

            Our new miniature bench is perfect for OEM integration in existing systems and handheld devices. The high numerical aperture AvaBench-37.5-HS has full mechanical compatibility for mounting holes with the AvaBench-75-ULS, which makes it convenient for OEM customers to upgrade to a higher-throughput optical bench.

            Wavelength ranges, resolution tables, detector specifications and AvaBench options can be found in the instrument page corresponding to each spectrometer type. In the table below, the key specifications of these optical benches are listed.

            All AvaBench optical benches are fully compatible with Avantes' electronics boards or may be interfaced to customer specific electronics. Video output is handled through a separate mini-coax cable.

          • OEM spectrometers: AvaBench NIR Optical Benches

          • For OEM applications in the NIR region, Avantes offers our line of AvaBench NIR optical benches. The AvaBench-50 optical bench is available in the 1000 to 1750 nm range for uncooled detectors. New in this line is the AvaBench-100TEC: a 100 mm optical bench offering optimal balance between optical throughput and resolution. To keep the size compact, it has a unique folding mirror built into it.

            All AvaBench NIR optical benches have symmetrical Czerny-Turner designs with a fiber-optic entrance connector (standard is SMA, other options are possible), a specially designed collimating focusing mirror and a diffraction grating. A choice of different NIR gratings can be selected with the products.

            Wavelength ranges, resolution tables, detector specifications and AvaBench options can be found in the instrument page corresponding to each spectrometer type. In the table below the key specifications of the NIR optical benches are listed.

            The NIR AvaBenches are fully compatible with Avantes' electronics boards or may be interfaced to customer specific electronics. The NIR optical benches have a separate video output through a mini-coax cable. The TEC NIR benches have a heatsink and additional electrical connections for both temperature sensor and power for the Peltier cooling.

          • OEM Spectrometers: AS-7010 Microprocessor Board

          • The AS-7010 is the electronic platform base for Avantes’ EVO spectrometer models.
            It is equipped with a powerfull Xilinx Zynq 7010 microprocessor. It combines the software programmability of a processor with the hardware programmability of an FPGA, resulting in unrivalled levels of system performance and flexibility. The generous 100 Mpixel memory enables onboard storage of spectra and custom programming. As it is equipped with two different AD convertors, optimal performance for each detector type is assured.

            The AS-7010 comes with the versatility of 2 communication ports: a high-speed USB3.0 and a GigaEthernet port.
            Also on board is the HD26 digital I/O connector with 13 programmable digital I/O ports, 2 analog out ports and 2 analog in ports. The connector is compatible with the AS-5216 I/O connector.

          • OEM spectrometer: Enclosures

          • For OEM customers Avantes offers a line of neutral black enclosures in which either 1 or 2 channel spectrometers can be integrated.

            The black enclosures have mounting ears and are available in single and dual channel housing.

            Both the AvaBench-45/75 and the AS-5216 electronic board fit into the 1-channel OEM housing. In 2-channel OEM housings 2 AvaBenches and 2 electronics boards will easily fit.
          • Developer kits for easy IO access

          • Avantes spectrometers feature great flexibility offering multiple Input/Output connections. These IO can be used with Avasoft 8 (Time Series) or with customized applications. The DEVKITs are intended to make life easier in the development stage. Instead of fabricating or soldering a cable with the right connections, you can now easily connect using the screw terminals.

            The AVS-DEVKIT-AS(C)5216 contains the PCB-IO-EXT-BES Printed Circuit Board. This board has several screw terminals for easy connectivity to the IO points, a BNC connector for the input trigger as well a push button for manual control. All outputs have a LED indicating their status (selectable with jumpers). Furthermore, RS232 connectors are provided. For the ASC version a power, USB and SYNC connector are on the PCB. The PCB-IO-EXT-BES will be connected to the AvaSpec-ULS or AvaSpecULSi IO Connector with an interface cable.

            Since the AS7010 and the AS5216 electronic boards share the same IO connections, the AVS-DEVKIT-AS5216 can also be used in combination with the AS7010.

        • Systems/bundles

        • Avantes offers an extensive line-up of preconfigured systems and bundles, each component carefully selected to give you the highest quality measurements.

          For specific measurements, we have created the Avantes spectroscopy bundles: a combination of products that are ideal for the application. Because of the flexibility of Avantes' products, these can always be used for different measurements later.

          Avantes is well-known for their multichannel spectrometer setup: two to many spectrometers, combined to have a combination of high resolution with high bandwidth.

          Our Raman systems come with either 532 or 785 nanometer lasers and can be combined with uncooled or cooled spectrometers, the latter feature a higher stability and longer possible integration times.

                  • AvaLight-DHc Full-range Compact Light Source

                  • Get the best out of two worlds with the AvaLight-DHc. It has both a deuterium light source and a halogen light source, providing you with adequate light between 200 and 2500 nm for nearly all absorbance chemistry applications. Deuterium emits light between 200 and 550 nm, where the halogen takes over up to 2500 nm. Coupling to the rest of your spectroscopy system is easy with the SMA connector.

                    This light source is recommended in settings with large fiber cables or direct-attachment to a cuvette holder such as the CUV-DA, due to its relatively low output energy. The integrated TTL-shutter makes saving a dark measurement very simple in combination with AvaSoft (extra IC-DB26-2 needed).

                    Optionally the AvaLight-DHc is available in a rack-mountable version, to be used in the 19” rack or the 9.5” desktop system.

                    • Combined deuterium-halogen
                    • Low cost
                    • Integrated TTL-shutter
                  • AvaLight-HAL-(S)-Mini

                  • From visible light to near infrared, that’s where the AvaLight-HAL-(S)-Mini works best. It’s a compact, stabilized halogen light source, with adjustable focusing of the fiber connection, maximizing output power at the desired wavelength. The light source also has adjustable output power to provide extra power or longer bulb life.

                    A filter-slot mounted on the front of the AvaLight-HAL-Mini accepts 1” round or 2” x 2” square filters, to block specific ranges of wavelengths or instantly lower the intensity.

                    The adjustable focus on the AvaLight-HAL-Mini helps you getting the most out of your light source: it makes sure all possible power is transmitted through your optical fiber. Bulb replacement is easy and can be done in a matter of minutes.
                  • AvaLight-D(H)-S Deuterium-Halogen Light Sources

                  • In need of more power than the AvaLight-DHc? The AvaLight-DH-S is Avantes’ most powerful deuterium halogen source. Like the DHc it is also a combined deuterium and halogen light source, capable of transmitting light in the UV/VIS/NIR-range, but has 35 times more halogen output and up to 300 times more deuterium power. The source has a prominent 656 nm deuterium peak which can limit dynamic range (see Avalight-DH-S-BAL as an alternative). It includes a focusing lens assembly, to fully utilize the possibilities and size of your fiber.

                    The AvaLight-D-S is a deuterium light source only, making it a great option for measurements in the UV range, 190-400 nm. The AvaLight-D-S-DUV version starts even lower at 175 nm, for your deep-UV experiments. This version also offers twice the intensity at 200 nm.

                  • In need of more power than the AvaLight-DHc? The AvaLight-DH-S is Avantes’ most powerful deuterium halogen source. Like the DHc, the DH-S is also a combined deuterium and halogen light source, capable of transmitting light in the UV/VIS/NIR-range, but has 35 times more halogen output and up to 300 times more deuterium power.

                    The output of the AvaLight-DH-S is optimized for fibers or bundles up to 600 micrometers. For larger fibers the focal point is manually adjustable to optimize the light coupling into your fiber.

                  • AvaLight-DH-S-BAL Balanced Power

                  • The AvaLight-DH-S is a powerful deuterium halogen source, but, like any unbalanced deuterium halogen source, it does have a very dominant alpha peak at 656 nm. This is why Avantes developed the DH-S-BAL, in which this peak is drastically reduced by a dichroic filter. This means less power, but an increase in the dynamic range of a factor 20. A comparison spectrum as taken with a standard AvaSpec-2048 is shown on the next page.

                    The light source delivers a continuous spectrum with high efficiency. The highest stability is in the ultraviolet, visible and near-infrared range, from 200 to 2500 nm. An integrated TTL-shutter and filter holder for filters of up to 50 x 50 x 5.0 mm are included. The TTL-shutter can be controlled from any AvaSpec spectrometer, which means the auto-save-dark option in AvaSoft software can be used (please note: IC-DB26-2 cable is needed).

                  • AvaLight-XE-HP

                  • The AvaLight-XE-HP is a pulsed xenon light source, perfect for ultraviolet applications, such as fluorescence. This high-power light source comes in a compact housing, which makes it very well-suited for integration into a customer’s existing systems. Compared to the AvaLight-XE (2W), the XE-HP provides significantly more power.

                    When connected to your AvaSpec spectrometer through the Y cable, the flashes are synchronized with the data collected by the spectrometer. The number of flashes per scan can be selected in AvaSoft.

                  • AvaLight-XE

                  • The AvaLight-XE is a pulsed xenon light source, perfect for ultraviolet applications like fluorescence. When connected to your AvaSpec spectrometer through the IC-DB26-2 cable (sold separately), the flashes are synchronized with the data collected by the spectrometer. The number of flashes per scan can be selected in AvaSoft.

                    With a special DUV bulb, the AvaLight-XE can be used for deep-ultraviolet applications (below 200 nm). A special direct-attach cuvette holder is available for your fluorescence applications. For transmission measurements, the Avalight-XE can be used in conjunction with the CUV-ATT-DA which has an iris attenuator to limit the light output and to avoid saturation.

                  • AvaLight-HAL-CAL-Mini & DH-CAL

                  • Calibrating your spectrometer has never been easier: the AvaLight-HAL-CAL-Mini and Avalight-DH-CAL are NIST(National Institute of Standards and Technology) traceable, calibrated light sources to measure absolute spectral intensity with.

                    The AvaLight-HAL-CAL-Mini is a compact, affordable light source. It is calibrated for the visible range (350-1095 nm). Optionally, an extended calibration for the near-infrared spectral range (1100 – 2500 nm) can be ordered. It has a built-in diffuser, a cosine corrector with SMA adapter and comes with a calibration file in ASCII format. Calibration can be done using the AvaSoft software.

                    The AvaLight-HAL-CAL-ISPxx-Mini is a special version of the Avalight-HAL-CAL-Mini, which enables coupling any of Avantes’ AvaSphere-xx-IRRAD integrating spheres to the lightsource (xx = 30, 50 or 80) for calibration. This source is supplied with a special bottom plate to stabilize the AvaSphere. The Avalight-HAL-CAL-Mini and Avalight-HAL-CAL-ISPxx-Mini include a power supply.

                  • AvaLight-CAL-(Mini) Spectral Calibration Source

                  • The AvaLight-CAL-xxx is a spectral calibration lamp, available in Mercury-Argon (253.6-922.5 nm), Neon (337-1084.5 nm), Argon (696.5-1704 nm) Zinc (202.5-636.2 nm) and Cadmium (214.4-643.8 nm) versions. The major lines including their relative intensity and structures are shown below.

                    The standard SMA-905 connector supplies an easy connection between the lamp and optical fibers, making the AvaLight-CAL-xxx a low-cost wavelength calibration system for any fiber-optic spectrometer. AvaSoft-Full spectroscopy software includes an automatic recalibration procedure.

                    The AvaLight-CAL-Mini, AvaLight-CAL-AR-Mini, AvaLight-CAL-Neon-Mini all come in the Mini-housing and are equipped with a connector at the rear enabling to switch the unit on/off remotely with a TTL signal.

                • Fiber-optics

                • The use of fiber-optics as light guidance allows a great modularity and flexibility in the setup of an optical measurement system. Optical fibers can be made of many materials, such as plastic, glasses and silicates (SiO2). For high quality fiber-optics, as used in spectroscopic applications, synthetic fused silica (amorphous silicon dioxide) is used, that can be intentionally doped with trace elements to adjust the optical properties of the glass.
                    • Fiber-optic Cables

                    • Avantes offers a wide range of fiber-optic cables, which can be made in a variety of lengths and configurations to meet your needs. For common applications, a 2 meter length is sufficient and for this reason it is our standard fiber length.

                      Avantes offers SMA-905 or FC/PC connectors and these can be the same or different on both ends. For some applications, special round to linear fiber cables are recommended in which a bundle of fibers configured in a round pattern on one end and a linear array on the other end. The linear array (typically 1 mm in height) is aligned with the slit height of the spectrometer which is also 1 mm. This fiber configuration provides maximized light throughput for applications requiring high-sensitivity.
                    • Multi-furcated Fiber-optic Cables

                    • Simultaneous multi-point measurements and Avantes multi-channel spectrometers, require multi-furcated fiber-optic cables. These assemblies can function as a combiner or splitter of light as they have multiple legs on side which converge into a single connector on the opposite side. Avantes offers virtually any combination possible, which can be adapted to your requirements.
                      Typical setups that require multi-furcated cables are:
                      • One sampling point such as an integrating sphere, cosine corrector or collimating lens being measured from several spectrometers (individual AvaSpecs or Multi-channel).
                      • Multiple illumination fibers splitting out from one light source to different sampling points.
                    • Reflection Probes with multiple legs

                    • For some measurements, a reflection probe is needed that can be coupled to two spectrometers and a light source. A good example is a reflection measurement in the UV/VIS and NIR range. For these situations, Avantes offers our reflection probes with multiple legs.

                      The light from a light source is coupled into a fiber bundle, consisting out of 17 illumination fibers which transport the light to the end of the probe. The reflected light is uniformly reflected into the two read fibers, each of which is connected to a spectrometer. In the example of a UV/VIS and NIR configuration a mix of high OH UV/VIS fiber and low OH VIS/NIR fibers are used for the respective light wavelengths and spectrometer types.
                    • Reflection Probe (Standard)

                    • To obtain spectral information of diffuse, or specular materials, reflection probes are used. The light from a light source is sent through six illumination fibers to the sample and the reflection is measured by a 7th fiber in the center of the reflection probe tip. The 7th fiber is coupled to a spectrometer configured to the appropriate wavelength range of interest. More illumination fibers can be added to get more energy from the light source and therefore increase the reflection signal level.

                      For measurements under an angle of 90°, the FCR-90-Option was developed. It’s a special adapter with a mirror positioned at 45° and can be easily mounted on the tip of Avantes standard reflection probes.
                    • Reflection Probes with Reference

                    • In order to correct fluctuations and drift from your light source, periodic referencing is required. To facilitate this, Avantes offers this series of reflection probes with a self-referencing feature. The light coming from the light source is bundled into 12 fibers, which are split into two 6 fiber bundles. One of these bundles is carried to the probe end for sample measurement and the other bundle of 6 are directed to a white reflection tile built into the probe to provide a light source reference. This reference leg is connected to a slave spectrometer channel dedicated to light source referencing or may be routed to a single channel via a fiber-optic (contact a Sales Engineer about this special configuration). On the measurement side the probe end has a 7th fiber which reflects light back to the master spectrometer channel.
                    • Reflection Probes with small tips

                    • For some medical and semiconductor applications, a (very) small tip is desirable to do reflectance measurements. Avantes offers two standard diameters of small tip reflection probes, 1.5 and 2.5 mm and each tip is normally 100 mm long (custom lengths available).

                      The probe is configured with an illumination leg with six 200 μm fiber cables which connects to a fiber coupled light source and a single 200 μm read fiber cable to measure the reflection via connection to a spectrometer.

                      A special angled fiber holder (AFH-15) is available for the 1.5 mm diameter reflection probe. This device enables reflection measurements under angles of 15, 30, 45, 60, 75 and 90 degrees.
                    • Reflection Probes for Powders and Thick Fluids

                    • For effective measurement of reflection in powders and thick fluids, Avantes offers this specially designed this series of reflection probes. The probes allow the user to simply dip the probe into the powder or thick fluids to do the measurements.

                      The illumination leg of the probe is connected to a light source and carries light to the sample via a bundle of six fibers. At the probe tip, a 45 degree sapphire window illuminates the sample and collects the indirect reflections which are carried by a single fiber to the spectrometer. The 45 degree angle of the probe prevents the measurements of direct back reflection from the window, thus improving the dynamic range of your measurement.
                    • 1/2" Industrial Reflection Probes for Powders and Thick Fluids

                    • For industrial applications that need reflection measured in thick liquids or powders, this probe is the ideal choice. The stainless steel cylinder and probe end make it withstand extreme situations. The tip is exchangeable and waterproof. Optionally PEEK or Hastelloy® C276 can be used as tip material.

                      The light enters from the light source through six bundled fibers to the probe end, where it lights the material to be analyzed through a silica window angled at 45 degrees. This angle prevents any light to be reflected from the window. The light is selectively reflected through the seventh fiber in de probe. This fiber leads to the connected spectrometer.
                    • 1/2" Industrial Fluorescence Probe

                    • For effective measurement of fluorescence, Avantes offers this specially designed reflection probe. It features 12 excitation fibers of 200 μm around a 600 μm read fiber, which transports the fluorescence signal back to the spectrometer.

                      To turn the 45° reflection probe into a fluorescence probe, a special reflector accessory, FCR-FLTIP-IND, is attached to the probe end. It prevents ambient light to enter the probe and backscatters the excitation light. This increases the typically low fluorescence signal. The fluid channel path can be varied between 0 and 5 m
                    • Mini Transmission Dip Probe

                    • For absorption measurements in miniaturized centrifuge tubes or vessels, Avantes offers the mini transmission dip probe. It features a miniaturized tip which is 130 mm long and 3.2 mm in diameter.

                      The mini transmission dip probe has a fixed 5 or 10 mm optical path length. It is available in three different versions: one for UV/VIS (200-800 nm) measurements, one for VIS/NIR (350-2500 nm) and one for UV/VIS/NIR (250-2500 nm). For best results below 240 nm, solarization resistant fiber (-SR) is recommend. The probe features Avantes ME, chrome plated brass, jacketing.
                    • Transmission Dip Probes

                    • For online and inline absorbance measurements in fluids, transmission dip probes are used. When dipping or permanently mounting the probe end into the fluid, absorbance can be measured.

                      A standard SMA-905 connector is used to couple light into a fiber bundle, typically consisting out of six fibers (other configurations available upon request). The light is transmitted to the probe end, where it crosses the predetermined gap and is then reflected against a diffuse white reflective material back onto the receiving read fiber, which is coupled, to a spectrometer on the second leg of the probe.
                    • Transmission Dip Probe with Variable Path Length

                    • For more flexibility during absorbance measurements in fluids, this fiber-optic probe features a variable and adjustable path length. The gap between the fiber and the diffuser can be set anywhere between 0.25 and 10 mm.

                      A standard SMA-905 connector is used to couple light into a fiber bundle, typically consisting out of six fibers (other configurations available upon request). The light is transmitted to the probe end, where it crosses the predetermined gap and is then reflected against a diffuse white reflective material back onto the receiving read fiber which is coupled to a spectrometer on the second leg of the probe.
                    • Special Fiber Assemblies and Probes

                    • For some applications a very specific fiber or probe is needed. Avantes has over 20 years of experience in designing the custom probes for unique applications. Avantes has significant expertise in designing fiber-optics for high temperature (HTX), high pressure (HP), vacuum and other difficult conditions. Avantes wide variety of standard and custom materials can be configured to provide a fiber assembly which can meet the challenges of your environment.

                      Below are some examples of our special designs. Please contact us to discuss your needs.
                    • Collimating Lens

                    • To convert divergent beams of light into a parallel beam, a collimating lens is needed. Avantes collimating lenses are optimized for the UV/VIS/NIR range (200-2500 nm) and have anodized aluminum housings.

                      The COL-UV/VIS and COL-90-UV/VIS have a 6 mm diameter lens with a confocal length of 8.7 mm. The COL-90-UV/VIS is used when a 90-degree exit angle is needed. The focal point for the COL-UV/VIS and COL-90-UV/VIS can be adjusted. The COL-UV/VIS can also be ordered with an FC/PC connector.

                      The COL-UV/VIS-25 is the big brother of the COL-UV/VIS. It has a lens diameter of 25 mm and a confocal length of 50 mm. This larger collimating lens is suitable for collection of light in free space.
                    • Cosine correctors

                    • To collect light from a 180° angle, cosine correctors are used. This eliminates optical interface problems associated with the light collection sampling geometry inherent
                      to other sampling devices such as bare fiber-optics, collimating lenses or integrating spheres.

                      Avantes offers four different models of cosine correctors: The CC-UV/VIS and CC-VIS/NIR have a 3.9 mm active area, and dimensions of 18 mm (L) X 6.5 mm (OD). The CC-UV/VIS is made of Teflon which especially suited for measurements in the 200-800 nm range, whereas the CC-VIS/NIR covers the full UV/VIS/NIR range of 200-2500 nm and is made of Radin Quartz.
                    • Vacuum Feedthrough

                    • These feedthroughs are designed for the use with fiber-optics in vacuum chambers, such as for plasma and coating deposition monitoring. They can be used in chambers with wall thicknesses of 5-40 mm and vacuum levels up to 10-7 millibar.

                      The feedthrough assembly consists of an M12 housing with Viton® O-ring and two SMA fiber-optic interconnects to allow easy coupling to fiber-optic cables and probes. In order to connect these assemblies to fiber-optic cables inside/outside the chamber, two extra SMA fiber interconnects (ME-FI-SM-MM) should be ordered separately.
                    • Fiber Microscope Adapters

                    • To easily mount an Avantes fiber-optic spectrometer to a microscope, a C-mount adapter is available. It connects to an SMA or FC/PC fiber-optic cable and features an outside diameter of 38 mm, 35 mm long to slide inside the tube of a microscope.

                      A special adapter with C-mount 1 inch-32 thread is available as AVS-MFA-SMA to screw onto a microscope.
                    • Fiber-optic homogenizer

                    • When connecting a multi-furcated fiber to a spectrometer or light source, light entering/exiting each of the fiber legs may or may not be uniform, so a fiber-optic homogenizer can be used to mix the signals to provide more uniform signal.

                      The compact MMA-UV/VIS-SMA fiber-optic homogenizer is made of anodized aluminum and has female SMA-905 connectors on both ends. Internally, a highly transmissive Suprasil-Rod with a diameter of 1 or 3 mm transmits the light from one end to the other (from bundle to single fiber) and perfectly mixes the modes.
                    • Reflection Probe Holders

                    • The RPH-1 is to be used with our standard reflection probes, which are 6.5 mm in diameter. The holder enables positioning of the probe tip in two angles: 45 degrees for diffuse reflection measurements and 90 degrees (normal to sample) for specular reflection. This assembly is mostly used to facilitate color measurements.

                      A setscrew is included to mount the probe into position. The RPH-1 is a small device, measuring only 60 by 30 by 30 millimeters. It’s made of black anodized aluminum.
                    • Fiber Interconnects

                    • To connect one fiber to another, a fiber interconnect is needed. They can be useful for coupling patch cords to fiber-optic probes and other devices, or for any multiple-fiber application where coupling of standard optical fibers and accessories is preferable to creating costly and complex fiber-optic assemblies.

                      Avantes bulkhead adaptors for TO-5 and TO-18 packages are ideal for coupling an LED to a fiber-optic cable: the back side has space for an LED.

                            In the field of chemical spectroscopy, there are an unlimited number of applications. Chemical reactions are dynamic processes that vary with changing conditions which result in a various way of techniques.

                            From enzyme reactions within our cells to photosynthesis in leaves, chemical reactions play a vital role in every aspect of our lives. Factors like concentration, temperature, pressure and the presence of a catalyst affect the speed of a reaction. The study of chemical kinetics is used to characterize these processes and improve our understanding of how these factors and others change the outcome of a chemical reaction.

                          • Fast and Accurate

                          • Ecosystems around the world are facing growing threats. The increasing pace of industrialization, pressure from growing populations and increasing urbanization, as well as climate changes can wreak havoc on emerging economies and have health and social implications. Not surprisingly, researchers, scientists and governments are investing significant resources to monitoring and preventing these environmental hazards.

                            The semiconductor industry can realize significant benefits from spectroscopic measurements during various stages of their processes. Fiber-optic based spectrometers offer a great value to the industry due to their ability to facilitate in situ measurements within processing environments and facilitate near real-time analysis.

                            Avantes works with semiconductor applications such as end-point detection for plasma ion etching, ion beam etching, photoresist stripping, and chemical/mechanical polishing. Instrument configurations have also been deployed in environments for thin film metrology (inline and offline) and plasma diagnostics.

                          • Solar Energy

                          • Diverse Measurement Needs

                            Sunlight is defined as the total spectrum of the electromagnetic radiation emitted by the sun. On Earth, sunlight is filtered through the atmosphere, and the solar radiation is visible as daylight when the sun is above the horizon. When the direct radiation is not blocked by clouds, it is experienced as a combination of bright light and heat.

                            The sun is the primary source of energy on Earth. Radiation from the sun strikes the Earth’s atmosphere and begins to be absorbed by air particles and gases, while the remaining energy reaches the Earth’s surface. Earth absorbs much of this radiation, and reflects and emits radiation as well. Even small changes to the balance of this energy system is believed to be able to cause intense shifts in the Earth’s climate.

                            The measurement needs of the solar industry are quite diverse, ranging from process control applications in the manufacturing of thin film photo-voltaic panels through direct solar measurements and solar simulator characterization.

                            Avantes has worked closely with a number of industrial and research customers in the solar industry to design spectroscopy and spectroradiometry systems which meet the demands of this fast growing industry.

                        • Measurement Techniques

                        • Spectroscopy allows us to measure materials in many different ways. It depends on your needs to decide which technique will suit you best.
                            • Reflection

                            • Material Characterization

                              Reflection spectroscopy, often called reflectance spectroscopy, is often used to non-invasively and non-destructively characterise objects and materials. Comparing the reflected light to the light used for illumination, can tell you a lot about the characteristics and nature of the object or material being researched, for instance exact colors, compounds and more.

                              When light hits a surface of a material it will either be reflected, absorbed or transmitted through the material (or a combination of the above). The reflectance of this light will depend on the structure and the material properties of the object.

                              Depending on the reflectance application, a wide variety of light sources, accessories, fiber-optic probes and spectrometers can be chosen, offering you a tailor-made solution for your specific application.

                            • Transmission

                            • Measuring Through Materials

                              When the object or material you want to measure is more transparent, for instance a filter, glass or fluid, the amount of reflected light is too low to perform a reflection measurement. For (mostly) transparent materials, transmission spectroscopy is the best choice, since it measures the light that passes through the material in comparison to the emitted light, instead of light that reflects from it.

                              To perform such a measurement, usually a parallel lightbeam is used while utilizing collimating lenses between the fiber optics of the setup. The object of interest is then placed between these collimating lenses to measure what light is transmitted through the material.

                            • Absorbance

                            • UV/VIS/NIR Absorbance

                              The absorbance (also called optical density) of a material is a logarithmic ratio of the radiation falling upon a material, to the radiation transmitted through a material. UV/VIS absorbance measurements encompass a wide variety of chemical and biochemical applications which involve many areas of research and industrial end uses. UV/VIS absorbance can be applied qualitatively and quantitatively in spectroscopic measurement applications ranging from blood parameters to chemical concentrations in process and reaction monitoring.

                              Fiber-optic spectrometers offer a tremendous value proposition for UV/VIS measurements because of their relatively low cost, small size and ability to be introduced in harsh environments through the fiber interface. Combined with a fiber-optic transmission dip probe, inline flow cells or the more traditional cuvette cell, a fiber-optic spectrometer can accurately and repeatably measure over the range from 200-1100 nm.

                            • Irradiance

                            • Irradiance and Radiometry

                              Radiometry deals with the measurement of all optical radiation inclusive of the visible portion of this radiant energy. Irradiance is a parameter of radiometry. It describes the amount of radiant power impinging upon a surface per unit area. These measurements can be done in the UV, VIS and NIR wavelength ranges.

                              Avantes works with a variety of irradiance applications ranging from pulsed solar simulator characterization to free space measurements of radiant sources such as street lights.

                            • Fluorescence

                            • Fluorescence Analysis

                              Fluorescence spectroscopy, also known as fluorometry or spectrofluorometry, is a type of electromagnetic spectroscopy, which analyzes fluorescence from a sample. It involves using a beam of light that excites the electrons in molecules of certain compounds and causes them to emit light; typically, but not necessarily, visible light. It is a useful technique in many biological (chlorophyll and carotenoid), biochemical (diagnosis of malignancies) and environmental applications.

                              For most fluorescence applications the amount of fluorescent energy emitted is only 3% of the amount of excitation light energy. Fluorescent light has a lower energy (higher wavelength) than the excitation energy and is usually scattered light. This means it emits energy in all directions.

                            • Raman

                            • Material Identification and Monitoring

                              Raman spectroscopy is a technique that characterizes inelastic scattering of photons in covalently bound molecules. This scattering is then used to define the material’s so-called molecular fingerprint, crystallinity and other specifications. Raman provides an invaluable analytical tool for molecular fingerprinting used in material identification, as well as monitoring changes in molecular bond structure (e.g. state changes, stresses and strains).

                              Avantes uses the high-sensitivity AvaSpec spectrometers in combination with a wide variety of lasers (including 532 and 785 nm) to give you the best result for your Raman measurements. The spectrometers are appropriately configured according to the wavelength of the laser.

                            • DOAS

                            • Differential optical absorption spectroscopy, or DOAS, is a technique that is used to monitor pollutants in the atmospheric air. This form of spectroscopy is often used in continuous emission monitoring systems (CEMS).

                              Avantes instruments are integrated into a variety of CEMS around the world. Due to the high stability requirements of this technique, any of the Avantes thermo-electrically cooled spectrometers are used in this application.

                              Though it has been around for a few decades, nowadays DOAS is performed by recording two absorption spectra, one as a reference scan through a column of atmosphere (ideally) free of contaminants and one through an identical pathlength containing the contaminant that needs to be analyzed. The light traveling through the measured atmosphere is partially absorbed by trace contaminants along the way following Lambert Beer’s Law of Absorption.

                            • LIBS

                            • Fast and Non-Destructive

                              Laser-induced breakdown spectroscopy (LIBS) is a type of atomic emission spectroscopy that employs a laser to ablate or vaporize a microscopic layer of a sample’s surface. The resultant plasma caused by this laser ablation process emits light as it cools. This light is then collected and analyzed with a spectrometer for quantitative and qualitative material analysis.

                              This rapid chemical analysis technique offers many advantages compared to other elemental analysis techniques:

                              • A sample preparation-free measurement experience
                              • Extremely fast measurement time, usually a few seconds, for a single spot analysis
                              • Broad elemental coverage, including lighter elements, such as H, Be, Li, C, N, O, Na, and Mg
                              • Versatile sampling protocols that include fast raster of the sample surface and depth profiling
                              • Thin-sample analysis without the worry of the substrate interference
