QHY600M-PH SBFL

The QHY600M-PH SBFL (Short back-focal length version) is specifically created for users of DSLR lenses or individuals with specific
requirements for a short back focal length. This version features a unique front part with a back focal length of only 14mm. The QHY600M is capable of seamlessly connecting with Canon/Nikon lenses, even when a filter wheel is involved. Additionally, there is a 4mm hole on the side of this adapter that allows for the connection of an air pump via a plastic pipe, ensuring prevention of dewing on the glass when needed.

Native 16-bit A/D:
The new Sony sensor incorporates an on-chip native 16-bit analog-to-digital converter (A/D). This results in a genuine 16-bit output with 65536 distinct levels. Compared to 12-bit and 14-bit A/D converters, a 16-bit A/D provides higher sample resolution and a system gain of less than 1e-/ADU, eliminating sample error noise and minimizing read noise.

BSI:
The back-illuminated CMOS structure offers an advantage in terms of improved full well capacity, particularly for sensors with small pixels. In a typical front-illuminated sensor, photons from the target must pass through the metal wiring above the photosensitive layer, causing some photons to be reflected and reducing the sensor's efficiency. In a back-illuminated sensor, light enters the photosensitive surface from the reverse side, with the wiring structure located below the photosensitive layer. This allows more photons to strike the photosensitive layer, generating and capturing more electrons in the pixel well. The ratio of photon to electron production is referred to as quantum efficiency, and higher quantum efficiency results in better photon-to-electron conversion, making the sensor more sensitive to capturing faint details.

Zero Amp Glow:
This camera also exhibits zero amplifier glow making calibration easier.

TRUE RAW Data:
In DSLR implementations, the RAW image output is not entirely raw, often displaying evidence of noise reduction and hot pixel removal upon close inspection. This can have a detrimental effect on astronomical images, leading to issues like the "star eater" effect. However, QHY Cameras offer TRUE RAW IMAGE OUTPUT, ensuring that the resulting image consists solely of the original signal. This allows for maximum flexibility in post-acquisition astronomical image processing programs and other scientific imaging applications.

Anti-Dew Technology:
Drawing on years of experience in cooled camera design, QHY's cooled camera incorporates comprehensive dew control solutions. The optic window includes a built-in dew heater, and the chamber is protected against internal humidity condensation. An electric heating board prevents dew formation on the chamber window, while the sensor itself remains dry due to the silicon gel tube socket design, which regulates humidity within the sensor chamber.

Powerful cooling:
In addition to dual-stage thermoelectric (TE) cooling, QHYCCD employs proprietary hardware technology to control dark current noise.
