Teseek QHY533M IMX533 Mono Camera 14Bit A/D 9 Megapixels Astronomical BSI Cooling Camera with 1GB DDR3 Memory

Description:
- QHY533M (mono) and QHY533C (color) have different interface designs to be more flexible to deal with different applications.

- Both QHY533M/C comes with an additional adapter for tripod interface. This makes it easier to shoot with DSLR lens.

- The threaded interface used on the exterior of QHY533M can be directly connected to a small filter wheel. This time, we are launching a special standard small filter wheel version together with QHY533M. Users can directly assemble it externally without removing the disc. When the QHY533M+filter wheel combination is connected to a DSLR lens, only an additional DSLR lens adapter ring (not included) is needed to complete focusing. QHY533M provides C-port thread, which can directly install C-port lens.

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 shot 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 shooting an image of something dim.

TRUE RAW Data:
- In the DSLR implementation there is a RAW image output, but typically it is not completely RAW. Some evidence of noise reduction and hot pixel removal is still visible on close inspection. This can have a negative effect on the image for astronomy such as the “star eater” effect. However,  QHY Cameras offer TRUE RAW IMAGE OUTPUT and produces 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, The QHY cooled camera has implemented the fully dew control solutions. The optic window has 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 our silicon gel tube socket design for control of humidity within the sensor chamber.

Cooling:
- In addition to dual stage TE cooling, we implements proprietary technology in hardware to control the dark current noise.
