NIT has introduced the WiDy SWIR camera, integrating an ultra-wide dynamic range IngaAs sensor operating from 900nm up to 1700nm.
WiDy SWIR uses a 320 x 256 pixels InGaAs photodiode array sensor, coupled to the NIT NSC0803 wide dynamic range read out circuit from NIT. The InGaAs photodiodes provide a high QE signal response from 900nm to 1700nm.
When used with the NIT WDR ROIC technologies the InGaAs photodiodes deliver more than 140 dB of dynamic range in a single image without any external control.
WiDy SWIR has a simple USB digital output and is delivered with WiDyWiew software operating under Microsoft Windows. The frame rate is software controllable from 1Hz to 150 Hz and can be synchronised from an external IO signal.
