With the advantage of low readout noise and high-speed readout, CMOS technology has revolutionized astronomical imaging. The QHY533M/C is a new generation of back-illuminated CMOS cameras with 3.76um pixels. The QHY533M/C uses the similar series of sensor as the flagship models QHY600 and QHY268, featuring low noise.

Native 16 bit A/D: The Sony sensor has native 16-bit A/D on-chip. The output is real 16-bits with 65536 levels. Compared to 12-bit and 14-bit A/D, a 16-bit A/D yields higher sample resolution and the system gain will be less than 1e-/ADU with no sample error noise and very low read noise.
BSI: One benefit of the back-illuminated CMOS structure is improved full well capacity. This is particularly helpful for sensors with small pixels. In a typical front-illuminated sensor, photons from the target entering the photosensitive layer of the sensor must first pass through the metal wiring that is embedded just above the photosensitive layer. The wiring structure reflects some of the photons and reduces the efficiency of the sensor. In the back- illuminated sensor, the light is allowed to enter the photosensitive surface from the reverse side. In this case the sensor’s embedded wiring structure is below the photosensitive layer. As a result, more incoming photons strike the photosensitive layer, and more electrons are generated and captured in the pixel well. This ratio of photon to electron production is called quantum efficiency. The higher the quantum efficiency, the more efficient the sensor is at converting photons to electrons, and hence the more sensitive the sensor is to capturing an image of something dim.
Zero Amplify Glow: This is also a zero amplifier-glow camera.
True Raw Data: QHY Cameras offer true raw image output and produce an image comprised of the original signal only, thereby maintaining the maximum flexibility for post-acquisition astronomical image processing programs and other scientific imaging applications.
Anti-Dew Technology: Based on almost 20-year cooled camera design experience, QHY cooled cameras have implemented a full dew control solution. The optic window has a built-in dew heater and the chamber is protected from internal humidity condensation. An electric heating board for the chamber window can prevent the formation of dew and the sensor itself is kept dry with a silicon gel tube socket design for control of humidity within the sensor chamber.
Cooling: In addition to dual stage thermoelectric cooling, QHY implements proprietary hardware technology to control the dark current noise.
Design: QHY533M (mono) and 533C (color) have different interface designs to be more flexible for different uses. with the adapter (below). This adapter is used to connect the small filter wheel to the QHY163 or QHY183, while QHY533M doesn’t need it. If you want to get a QHY533M, we recommend you choose QHYCFW3S-SR for the best experience.
QHY533M parallel position adjustment: The QHY533M is connected to the QHYCFW3S by using threads, so the sensor may not parallel to the filter wheel when the threads are fully rotated. In this case, you can adjust the front part of the 533M to the right angle of the sensor.
QHY533C Design: An Adapter Kit E is provided with QHY533C. The adapters can be directly connected to the 55mm BFL M48 interface MPCC, or Nikon / Canon DSLR lens (need to purchase another DSLR lens adapter). At the same time, the C-port thread can be provided with the QHY533C and you can directly mount the C-port lens.
