QHY268C-PRO-L CMOS IMAGER



QHY268PRO is a cooled scientific CMOS camera with a SONY IMX571 APS-C format CMOS sensor inside. 26mega pixels, Back-illuminated, native 16BIT ADC. QE is up to 91% and readout noise is as low as 1.1e Even with a 3.76um pixel size, it has a big full-well up to 75ke. It has extremely low thermal noise 0.0005e/pixel/sec @ -20C, ZERO amplifier-glow performance, It has a maximum frame rate of 6.8FPS@16bit full resolution. QHY268PRO has both USB3.0 and 2*10Gbps optical fiber interface. It has a 2GBytes big DDR3 memory buffer. It has the 6pin GPIO port support complex Trig-In and Trig-Out signal. It can connect with QHY GPS-BOX to get the high-precision GPS timestamp onto the image head. QHY268PRO has both monochrome version and color versions. QHYCCD also supplies the water cooling version. (Water cooling version is a customized version, needs to be pre-ordered). The QHY268PRO supports the Trig in/out function and GPS function. There is a 6pin GPIO socket on the camera backside. It can be configured into different modes. QHY600PRO also can be customized as the user requests to meeting more complex timing by re-programming the FPGA.

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.

Since most uses will match CFW with monochrome cams, please take 12.5mm as major reference. Check the mechanical drawing below for details.Note 14.5mm rear intercept does not include adapter thread, which must be used with adapters of various sizes through the top 6 screw holes. QHY268C: 17.5mm (without CAA)This intercept does not include CAA. If CAA is used, it increases by 6mm (23.5mm total). Please check the mechanical drawing below for details.
