ZWO ASI990MM PRO SCIENTIFIC SWIR CAMERA CEM 8mm (2") diameter filter andThe ZWO ASI990MM Pro 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 million effective pixels. This chip has a wide waveband (0. 4um 1. 7um) with high sensitivity. QE is estimated at 80% at 1200nm. By using Cu Cu interconnect technology, the sensor has very low fixed pattern noise and a low pixel defect ratio. Typically the InGaAs sensor has a higher dark
