QHY990M SCIENTIFIC SWIR CAMERA [MONOCHROME] Model:QHY990 Geoptik transport bag for largeThe QHY990M is a scientific cooled short wavelength infrared (SWIR) camera featuring the Sony IMX990 InGaAs sensor with a square 5m x 5m pixel array and 1. 3 Megapixels. This chip has a wide waveband (0. 4um 1. 7um) with high sensitivity. QE is up to 77% at 1200nm. By using Cu Cu interconnect technology, the sensor has very low fixed pattern noise and a low pixel defect ratio. Both QHY990M and QHY990M PRO II include a 25mm filter holder. The 25mm
