This product is assembled by flip-chip interconnecting a CMOS readout circuit chip with an InGaAs photodetector array chip. The array size is 320x265 pixels, with response wavelengths of 0.9-1.7 μm (standard wavelength) and 0.4-1.7 μm (visible wavelength) as optional choices. It offers performance advantages such as low noise, high sensitivity, excellent uniformity, and a wide dynamic range. It exhibits good reliability under both cooled and uncooled operating conditions. The product is available in two types: integrated with a TEC-type DIP metal housing for hermetic sealing and a lightweight compact CLCC packaging.
