The QHY533M/C is a new generation of CMOS cameras with back-illumination and 3.76 µm pixels. The QHY533M/C uses the same sensor series as the flagship models QHY600 and QHY268 and is characterised by low noise.
The QHY533M (mono) and QHY533C (colour) have different connectors to allow for more flexibility with different applications. The QHY533M can be connected directly to the QHYCFW3S-SR filter wheel without having to remove any parts of the filter wheel. This ensures a very short focal length and is easy to fix! In addition, the combination of QHY533M + QHYCFW3S-SR can be easily connected to a DSLR lens with just one additional adaptor (sold separately).
Both the mono and colour versions come with an additional adaptor for the tripod interface. This makes it easier to take photos with DSLR lenses.
BSI, back-illuminated CMOS structure:
One benefit of the back-illuminated CMOS structure is improved sensitivity. 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.
Cooling & Anti-dew Control: In addition to dual stage TE cooling, QHYCCD implements proprietary technology in hardware to control the dark current noise. 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.
Sealing Technology: Based on almost 20-year cooled camera design experience, The QHY cooled camera has implemented the sealing control solutions. The sensor itself is kept dry with our silicon gel tube socket design for control of humidity within the sensor chamber. By the way, there’s no oil leaking.
Mono or Color?
Mono:
- Capable of advanced techniques (LRGB, narrowband)
- Additional applications (spectrometry, photometry)
Colour:
- Convenient for RGB imaging
- No need for expensive filters and filter wheels
Both types of camera are capable of creating stunning astroimages, we can only recommend you pick the one that suits you best!
Accessories included:
- USB 3.0 cable
- Power cables with 12V adaptor
- The mono version includes an M42/2" adapter sleeve, while the colour version includes a C-mount/1.25".
- The mono version includes the F1 adaptor kit, the colour version includes the E1 kit.
