The QHY600PRO uses the latest SONY back-illuminated sensor, the IMX455, a full-frame (35mm format) sensor with 3.76um pixels and native 16-bit A/D. This sensor is available in monochrome and color versions. QHY600 is specially designed for scientific and high-end industrial applications, including the 2*10Gbps fiber interface, USB3.0 interface, 2Gbytes DDR3 memory, 6PIN GPIO / Trig / GPS connector.  Support 4.0FPS 16bit full-frame readout and 10FPS 14bit full-frame readout.



QHY600PRO 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.


QHY600PRO 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.


QHY600PRO includes some special versions. The super-short back focus version has a B.F.L as short as 7mm.  The water-cooled version can get typically 45C degrees below ambient with normal temperature water and can get up to 60C degrees below ambient with cold liquid.

Readout Noise 1.0e- to 3.7e-  (Standard Mode)
Dark Current 0.0022e-/p/s @ -20C    0.0046e-/p/s @ -10C
Exposure Time Range 40us – 3600sec
Unity Gain* 25 (Extended Full Well Mode) *


*With the improvement of the CMOS technology, the 16bit CMOS camera has been released, like QHY600/268/411/461. For these cameras, even in lowest gain it has beyond the requirement of unit gain (less than 1e/ADU due to sufficient samples) So you can directly set gain0 as start. Please note QHY600/268C/411/461 has extend full well mode. In this mode you still need to find out the unit gain position.
