QHY990/991/992 SWIR Series

QHY990 Series are scientific short wavelength infrared cameras with Sony InGaAs sensors, QE up to 77% at 1200nm. The chips have wide waveband (0.4μm-1.7μm) with high sensitivity.
QHY990 Series support both air cooling and liquid cooling. The air cooling can achieve -35℃ below ambient, while liquid cooling can get -45℃ with normal water and -60℃ to -80℃ with cold liquid. Typically InGaAs sensors have larger dark current compared with Silicon-based sensors, so powerful cooling methods are necessary.
Applications: SWIR Astronomy Imaging and Photometry, Daytime Star Observing, Optical Communication, Laser, Optic Labs.
