The QHY992M is a scientific cooled short wavelength infrared (SWIR) camera featuring the Sony IMX992 InGaAs sensor with a square 3.45µm x 3.45µm pixel array and 5.32 million effective pixels. This chip has a wide waveband (0.4um-1.7um) with high sensitivity. QE is up to 77% at 1200nm. By using Cu-Cu interconnect technology, the sensor has very low fixed pattern noise and a low pixel defect ratio.

The QHY992M  include a 25mm filter holder. The 25mm filter standard is common for lab applications. SWIR filters can easily be installed inside the camera with the included adapter, keeping the C-mount 17.5mm backfocus requirement.

The QHY992M is equipped with air cooling system that can reach -35C below ambient.

Typically the InGaAs sensor has a higher dark current than Silicon-based material. Like the other cameras in the 990 series, the QHY992M has a dark current of 64.6 e-/pixel at -30C below ambient at gain 0.


Sony's SWIR image sensor technology is used to make the top InP layer, which absorbs visible light, thinner, making it possible to transmit light to the InGaAs layer underneath, delivering high quantum efficiency even in the visible range. This design enables imaging in a broad range of wavelengths from 0.4μm to 1.7μm, enabling the use of a single camera instead of the conventional multiple that were required to capture visible light and SWIR.

Applications: SWIR Astronomy Imaging and Photometry, Daytime Star Observing, Optical Communication, Optic Labs.
