QHY990/QHY991 SWIR Camera

QHY990/991 is the scientific cooled short wavelength infrared camera.  with Sony IMX990 / IMX991 InGaAs sensor with a square 5um*5um pixel array and 1.31M / 0.4mega effective pixels. This chip has a wide waveband(0.4um-1.7um) with high sensitivity. QE is up to 77% at 1200nm. By using the Cu-Cu interconnect technology, the sensor has very low FPN noise and a low defect pixel ratio.

The difference between 990 and 991 is the pixel array for the 990 is 1296*1032 while the 991 is 656*520
