Sierra-Olympic Technologies (Hood River, OR) offers New Imaging Technologies' (NIT) wide-dynamic-range (WDR) indium gallium arsenide (InGaAs) shortwave-infrared (SWIR) sensors and camera systems. The SWIR imaging products deliver a dynamic range greater than 140dB in a single snapshot, without any processing or tone mapping. With uses in laser welding, among other applications, the sensors' internal Fixed Pattern Noise correction offers high-uniformity images under all lighting conditions.
The InGaAs photodiode array features a patented readout integrated circuit (ROIC). Available in 640 × 512 (with 15µm pitch) or 320 × 256 (with 25µm pitch) pixel resolution, both operate in the SWIR spectrum from 900 to 1700nm with high quantum efficiency. Power consumption is <1.5W.
NIT’s SWIR 640 and 320 camera modules offer digital video outputs in USB2.0 or Camera Link formats. Analog NTSC/PAL video is available on the Smart version cameras. The SWIR family of cameras with wide dynamic range is delivered calibrated, with software and cables in shock-proof cases. The cameras are easily exported under EAR.
