OptoSigma offers a wide range of application systems that includes microscope units, alignment systems, interferometers, bio-photonics, and laser processing systems. These application systems are designed for many specific applications including polarization measurements, vacuum and oven measurements, and glass and film inspections.
Hyperspectral imaging (HSI) is used for many applications including satellite imaging and air reconnaissance. HSI is usually executed with bulky hyperspectral-imaging cameras that are sensitive to misalignment, very expensive, and use prisms or gratings as dispersive elements. An alternative method of HSI is the combination of linear variable bandpass filters (LVBPFs) with silicon detectors. This allows for very compact, robust, and affordable HSI detectors that offer several advantages over conventional approaches.
The Nexview™ 3D optical profiler microscope stands out amongst competitive products by its ability to measure the topography of virtually any surface, irrespective of roughness, large steps and segments, thin films, steep slopes, with feature heights ranging from < 1 nm up to 20000 µm. It does all this in 3D, without contact, and provides the best qualities of other profiling technologies (stylus, confocal, focus scanning) without their limitations.
Iridian Spectral Technologies has developed filters and coatings for many satellites and low-earth orbit instrumentation for both terrestrial and stellar observation. This includes large format filters for astronomical observations (single band and multi-band pass filters), light absorbers/black coatings, dichroic mirrors and beam-splitters, and multi-element arrays.
First Sensor’s Series 9.5 Avalanche Photodiodes (APDs) are designed with enhanced NIR sensitivity to 950 nm, providing fundamental technology for the development of custom-designed solutions such as different geometries, packages, and arrays.
Bristol Instruments’ model 771 is a high-resolution laser spectrum analyzer that measures the spectral characteristics of CW and high-repetition rate pulsed lasers that operate from 375 nm to 12 μm. Laser wavelength is measured to +/- 0.0001 nm and spectral resolution is as high as 2 GHz.
Optics Blazers manufactures Near-Eye Display combiners and other components for optimized display performance and see-through properties. With an integrated manufacturing chain, this company can deliver single reflective surface, multiple reflective surface, free-form, or diffractive combiners. Optics Blazers’ solutions are developed with cost and scalability in mind to serve the competitive consumer electronics market.
Martin Ettenberg, with Princeton Infrared, gave us a breakdown on when and why you should use shortwave infrared imaging, and what this technology’s role can be as it relates to machine vision applications.
This year at Photonics West, Dan Ford with the Ophir Photonics Group talked to us about the importance of achieving laser consistency.
Jeff Briton and Dragan Grubsic spoke to us about some of the challenges involved in operating pulsed laser diodes and avalanche photodiodes in LIDAR for the automotive and sensor markets.
At Photonics West 2017, Gene Nepomuceno with Vision Research spent a few minutes with us discussing the three main factors one should take into account before selecting a high speed camera – resolution, frame rate, and sensitivity (with an honorable mention for transferring the data off of the camera).
At Photonics West 2017, Greg Staples focused on selecting different wavelengths for specific applications. Watch the video for wavelength selection guidance for precision agriculture, food sorting, mining, pharmaceutical quality control, and more.
