QHYCCD has introduced two new cooled science cameras for short-wave infrared (SWIR) imaging, the QHY990 and QHY991, based on Sony’s new SWIR InGaAs sensors (IMX990 and IMX991, respectively). Both sensors feature square 5-micron pixels, with array sizes of 1392*1052 (1.31 effective megapixels) and 752*520 (0.4 effective megapixels), with effective image sizes of 1/2-inch and 1/4-inch, respectively. The  sensors feature high sensitivity from 0.4 to 1.7 microns, roughly corresponding to the J and H bands of astronomical photometry, allowing for greater penetration into diffuse nebulae than visible and near infrared wavelengths. SWIR is also less affected by atmospheric water vapor, as well as light scattering during daytime imaging. Quantum efficiency is 77% at 1.2 microns.
