QHY550 has the 2/3inch SONY 5.0mega pixel IMX250 Global shutter CMOS sensor. Besides the monochrome and color version it has the special Polarize version.
Unlike the rolling shutter technology used in most cmos cameras, The Pregius is global shutter pixel technology for active pixel-type CMOS image sensors that use Sony’s low-noise CCD structure,and realizes high picture quality. For high speed moving object and the atmospheric agitation the pregius sensor can generate undisborted imaging.
QHY550 has build-in two stage TEC cooler. It can cooled the sensor to -35C below ambient. This can reduce the dark current of IMX250 significantly. Which greatly improving the dark signal detect performance. Especially for detect the tiny difference of the polarize light. Which is necessary for the astronomy, life science and optical lab.
