HOOD RIVER, Ore., 13 July 2016.Electro-optics distributor Sierra-Olympic Technologies Inc. in Hood River, Ore., is offering the Imaging Technologies (NIT) wide-dynamic-range (WDR), indium gallium arsenide (InGaAs) shortwave infrared (SWIR) sensors and camera systems for biomedical, laser measurements, welding, semiconductor, art inspection, and process control.
The SWIR imaging product family delivers a dynamic range greater than 140 decibels in one snapshot, without processing or tone mapping, and offers internal fixed pattern noise correction for high-uniformity images under all lighting conditions, Sierra-Olympic officials say.
The InGaAs photodiode array has a patented readout integrated circuit (ROIC). Available in 640 by 512 pixels (with 15-micron pitch) or 320 by 256 pixels (with 25-micron pitch), the sensors operate in the SWIR spectrum from 900 to 1700 nanometers with high quantum efficiency.
Power consumption is less than 1.5 Watts. By design, the proprietary NIT ROIC has proven to be functional for fast, triggered imaging applications such as range-gated imaging and synchronous illuminated imaging.

NIT's SWIR 640- and 320-pixel camera modules offer digital video outputs in USB 2.0 or Camera Link formats. Analog NTSC/PAL video is available on the Smart version cameras.
The SWIR family of cameras come calibrated, with software, cables, and shock-proof cases included. For more information contact Sierra-Olympic online at www.sierraolympic.com.
