SWIR QHY 990 & SWIR QHY991 (various versions available)
Two new cooled CMOS cameras QHY 990 and QHY 991 for the near infrared spectrum.
In September 2021, QHY began shipping 2 new camera models, the QHY990 and the QHY991. Both are cooled cameras with CMOS sensors covering the near infrared wavelength range.
Both models use Sony InGaAs sensors with square pixels measuring 5µm x 5µm. The IMX990 is a 1.3-megapixel sensor and the IMX991 has a 0.4-megapixel array. The spectral response starts at 400. and ends at 1700 nanometres. The maximum quantum efficiency is 77 % at a wavelength of 1200 nanometres.
