TECHNOLOGIES TO SEE AT SPIE PHOTONICS WEST 2018

Space, Satellite, and Astronomy Filters and Coatings

Iridian Spectral Technologies offers filters and coatings for satellites and LEO instrumentation, including 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.

• Digital Encoder Galvano Scanner: GM-1000 Series
• 640 x 512 Resolution High Speed IR Camera: FLIR X6900sc
• Application Systems

• Short-Exposure, High-Power Sensors With Industrial Communications Protocol: Helios Plus

  The Helios Plus measures high-power industrial lasers of up to 12 kW by measuring the energy of a short time exposure to this power. The laser is set to pulse from 0.3 to several seconds. It measures the energy and exposure time of this sample of the power, and from this calculates the power. By keeping the pulse energy under 5 kJ, there is no need for water cooling and the sensor can be kept to a compact size.

• Nexview™ 3D Optical Surface Profiler

  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.

• Linear Variable VIS NIR Bandpass Filters For Hyperspectral Imaging

  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.

• Color Filter Glass: UL365S UV Band-Pass Filter

  HOYA’s color filter glass products include sharp cut/long pass, light-balancing, color-compensating, neutral density, heat-absorbing, multi-band calibration, and UV Absorbing/VIS blocking filters for the UV through NIR regions. Featured is the new UL365S UV Band-Pass Filter that offers UV transmitting/VIS absorbing performance with high UV transmittance, while providing the highest resistance to any effects caused by UV solarization and/or exposure to high humidity conditions. 

• Laser Line Mirrors

  Optics Balzers has successfully developed and tested a special dielectric layer system with PARMS coating technology, making it possible to manufacture 45°-HR mirrors for 1030nm applications with an established destruction threshold of 0.44J/cm² at 210fs. These mirrors are typically used in ultra-short pulsed systems of Yb:YAG solid-state lasers.

• Compact sCMOS Camera pco.panda 4.2

  PCO introduces its latest camera innovation: the pco.panda 4.2, a state-of-the-art sCMOS camera featuring the same compact 65 x 65 x 65 mm dimensions. This camera provides outstanding quantum efficiency, up to 80%, and excellent image quality provided by the 16-bit sCMOS sensor.
