  • Multispectral Sensors

    PixelSensor - PIXELTEQ

    The unique, wafer-level optical filters split the spectrum into 8 discrete color bands and suppress out-of-band background light, improving contrast and sensitivity. Customized OEM versions are available with user-defined spectral bands. With narrow band VIS-NIR selectivity, the sensor arrays are available both with and without an OEM electronics board. The OEM electronics board is designed for easy integration into customers’ analytical equipment and provides a smaller footprint (45.72×21.34mm) and faster time-to-market than traditional sensor technology, offering a cost-effective solution. The parallel channel design results in no moving parts and faster measurements than discrete optics designs and spectrometers. Designed for low noise and fast response time, the 20-pin LCC package can be surface or socket mounted.

  • Connection Validation Soldering Station

    CV-5200 - Metcal

    Metcal soldering stations have led the way with SmartHeat® technology for 35 years. SmartHeat senses the thermal load and instantly delivers Power on Demand directly to the joint. The embedded, self-regulating heater delivers the right amount of power. The intermetallic compound thickness is critical in the formation of a solder joint. Connection Validation (CV) evaluates the quality of the solder joint by calculating the intermetallic compound formation and provides closed loop feedback to the operator. CV provides feedback to the operator via the LED light ring integrated in the hand-piece. It takes the risk associated with the variables involved in the soldering activity and removes the success and failure determination of a good solder joint out of the hands of the operator. CV compliments the skill of the operator to judge the quality of a solder joint by introducing an objective method of evaluating solder joint quality. This systemic and objective approach provides repeatability and a measureable standard to the soldering process.

  • Industrial Stroboscopes

    ELMED Dr. Ing. Mense GmbH

    ELMED stroboscopes for industry, maintenance, quality assurance and research Whether it’s for maintenance, production, research & development or within the framework of quality assurance: stroboscopes cover a wide field of applications. The human eye is not able to perceive single movements during quick and repeated moving processes. By the implementation of stroboscopes, these processes can be made perceivable. Light flashes produced synchronically to the movement illuminate thus the moving process continuously in the same position, leading to the creation of an apparent static picture. Vibrations, rotational and other periodical processes thus can be observed. A further classical field of application is the contactless speed measurement. By means of ELMED standard stroboscopes and their special versions the observer can perceive pin-sharp images of the single motion phases of rapid and periodic processes.

  • SWIR Microscopes with SWIR InGaAs Cameras

    Pembroke Instruments

    Our SWIR microscope cameras are designed to deliver superb image quality in real world conditions where intrascene dynamic range is quite high. This is accomplished through proprietary Wide Dynamic Range ROIC technologies and offer a Dynamic Range (DR) of more than 140dB in a single image without any external control. Other InGaAs cameras will suffer pixel saturation and deliver very poor image quality when the scene conditions demand high dynamic range from the camera. The internal Fixed Pattern Noise correction gives a high uniformity pictures in all light conditions with no need of Look-up table. The WDR InGaAs sensors use InGaAs photodiodes array operating from 900nm up to 1700nm with a high QE and coupled to a patented Read Out Circuit (ROIC).

  • Towing Dynamometer

    RSL-15K - Taylor Dynamometer, Inc.

    Taylor Dynamometer proudly introduces the RSL-15K Towing Dynamometer capable of testing today’s full-sized sedans and mid- to full-sized SUVs. Uniquely designed to be as light as possible in order to minimize the drawbar load for smaller vehicles, the RSL-15K can also be ballasted significantly to properly load larger vehicles. Thus, the RSL-15K is capable of testing a wide range of vehicles, making them unsurpassable in the industry. The RSL-15K is the first RSL model to receive Taylor’s robust, house-designed transfer case that appeals to extreme-duty cycle users needing additional durability. The axle disengagement feature converts the towing dyno into a free spinning trailer during transportation. Thus reducing concerns for over-spinning the retarder and alternator and being over-powered by the absorber rotor’s spinning mass while braking. In turn, it saves wear and tear on the towing dynamometer but more importantly, makes it much safer to transport.
