The QHYCCD medium size COLDMOS camera series includes all of our cooled cameras with CMOS sensor sizes from 1 inch to Full Frame (35mm Format) and includes BSI (back-illuminated) as well as FSI (front-illuminated) CMOS sensors in both monochrome and color cameras.

  • USB 3.0
  • Front-illuminated and Back-illuminated Sensors
  • Lightweight Compact Design
  • Regulated TE Cooling Delta -35C to -40C
  • 128 MB DDR Frame Buffer
  • ST-4 Compatible Guide Port
  • Filter Wheel Port
  • Anti-Noise Technology
  • Anti-Amp Glow Technology
  • Anti-Dew Technology

All models include a heated optical window to prevent external dew, a desiccant plug socket to help maintain a frost-free CMOS chamber, a 128MB frame buffer, a filter wheel port, and 2-stage TE cooling to reduce the sensor temperature to -35C or -40C below ambient along with temperature regulation to maintain a constant temperature set point.Due to the efficient TE cooling, single exposures many minutes in duration are possible, making them ideally suited for deep space imaging of dim objects as well as brighter objects and planets.The Horsehead Nebula image on the reverse side is only 3 x 20 minute single-shot color exposures.

Six of these medium sized COLDMOS cameras use Sony Exmor CMOS sensors, including the two largest with 24 and 36 Megapixels, respectively, in 35mm format sensors.Even these large sensors deliver multiple frames per second at full resolution.These front illuminated sensors also exhibit very high sensitivity.One model in this group (QHY163M/C) uses a Panasonic back-illuminated sensor and one model (QHY183M/C) uses a Sony STARVIS Exmore R back-illuminated sensor.STARVIS is Sony’s designation for sensors capable of recording under starlight.These back-illuminated sensors have even greater sensitivity as well as noise reduction - the key factors to enhancing image quality, while radically realigning their fundamental pixel structure from front-illumination to back-illumination.They retain the advantages of CMOS image sensors such as low power consumption and high-speed operation while dramatically improving sensitivity.
