QHY QHY550M Cooled CMOS Monochrome Camera

The QHY550M CMOS monochrome camera uses the Sony IMX250 Global Shutter CMOS sensor. Even with quickly moving objects and atmospheric agitation, the Pregius IMX250 sensor can produce images free of distortion.

The AR+AR coated optical window avoids halos around bright stars. This gives full access to the red wavelength of H-alpha and SII. For RGB color balance, a separate removable 2-inch UV/IR filter is placed in a custom filter holder in front of the camera. This is done without passing the near IR wavelengths above 700nm.

Detecting the tiny differences of light is necessary for astronomy, life sciences, and optical lab work. In order to cool the sensor to -35C below ambient, the QHY550 comes with a 2-stage TEC cooling system. This cooling system reduces the dark current of the IMX250 sensor significantly and improves the dark signal detecting performance.

Internet Interface and Frame per Second Rate

QHY has designed the QHY550 camera body with an USB3.0 interface. The CMOS monochrome camera is able to get 67fps @ 5 MP @ 8bit output. With a 12bit output, the camera can get 34fps. With the ROI function, the QHY550M can get hundreds of frames per second.

The Anti-Dew Technology

The QHY550M camera features full anti-dew technology. The QHY has included an electric heating board made for the chamber window to prevent dew formation. The sensor is kept dry using a silicon gel tube socket design to control humidity in the sensor chamber.
