QHY990/991 Series are scientific short wavelength infrared cameras. With Sony IMX990/IMX991 InGaAs sensor, a square 5um*5um pixel array and 1.31M/0.4M effective pixels. The chips have 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.
QHY990/991 Series cameras include 25mm filter holders. 25mm filter is a very common filter type for lab applications. The SWIR filter can be easily installed on the camera with a 17.5mm C-mount B.F.L.
QHY990Pro II have both air cooling and liquid cooling version (customization). The air cooling can get the -35C below ambient. The liquid cooling version can get -45C below ambient with normal temperature liquid and can get -60 to -80C below ambient with cold liquid. Typically the InGaAs sensor has a high dark current than Silicon-based material. If you need long exposure (e.g., >5 sec) ,we recommend the liquid cooling version.
