The QHY990/QHY991 SWIR cameras are scientific short-wavelength infrared cameras equipped with Sony IMX990/IMX991 InGaAs sensors. Let’s explore their features:

  1. Sensor and Resolution:

    • Both the QHY990 (monochrome) and QHY991 (color) cameras use the Sony IMX990/IMX991 InGaAs sensor.
    • The sensor has a square pixel array with 5μm x 5μm pixels and provides 1.31M/0.4M effective pixels.
    • These chips have a wide waveband sensitivity range from 0.4μm to 1.7μm with high sensitivity.
    • Quantum efficiency (QE) is up to 77% at 1200nm.
  2. Low Noise and High Sensitivity:

    • By using Cu-Cu interconnect technology, the sensors exhibit very low fixed pattern noise (FPN) and a low defect pixel ratio.
    • The QHY990/QHY991 cameras include 25mm filter holders, commonly used for lab applications.
    • The SWIR filter can be easily installed on the camera with a 17.5mm C-mount back focal length (B.F.L.).
  3. Cooling Options:

    • The QHY990Pro II version offers both air cooling (achieving -35°C below ambient) and liquid cooling (customization).
    • The liquid cooling version can achieve temperatures as low as -45°C below ambient with normal temperature liquid and even -60°C to -80°C below ambient with cold liquid.
  4. Applications:

    • SWIR Astronomy Imaging and Photometry
    • Daytime Star Observing
    • Optical Communication
    • Laser and Optic Labs

. Its high sensitivity and cooling options make it a valuable tool for researchers and observatories

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 (eg. >5 sec), we recommend the liquid cooling version.
