Details
This is a full-frame monochrome cooled camera, equipped with a Sony IMX455 back-illuminated sensor. The sensor is 9576×6388 pixels (61mp), each 3.76µm in size, giving an overall dimension of 36.0 x 24.0mm.
This is a model in the Pro series of cameras – intended for institutional use. It can connect to a computer using USB3, but it can also connect to a PCIE card via optical fibre. Not only is this connection method much faster, but it also allows a far longer cable between the camera and the imaging computer.
This camera is in used condition but has been refurbished by QHY in China. It has not been used since its refurbishment.
The QHY600M-Pro series camera
QHY600 Pro has a back-illuminated structure technology, QE is up to 90%. It has a very low readout noise performance, it can get 1.1e- at the highest gain. It has a typical 51ke full-well in high gain readout mode and a typical 80ke readout in extending full-well mode. The camera supports the 2-cms readout mode (sample the same signal twice and averaged on the sensor) and it can get the readout noise 1.3times less than normal readout mode.
QHY600 Pro has two data interfaces: USB3.0 interface and 2*10Gbps fiber interface. With 2*10Gbps fiber interface, it can get 4FPS @ 16bit full resolution and 10FPS @ 14bit full resolution frame rate under live streaming mode.
QHY600 Pro has an extremely good linear response in the whole full-well range. Please check the following document of the QHY600 Linear Test. It also has zero amplifier glow and zero RBI remains performance.
Native 16 bit A/D: The new 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. 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.
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.
Zero Amplifier Glow: This is also a zero amplifier glow camera.
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. (And if you’ve read this far, I assure you that this last sentence is taken verbatim from the QHY website!)
