Back Illumenlated CMOS Sensor
An extremely high sensitivity BSI CMOS sensor IMX290 is installed in QHY290 camera.This sensor has very high QE and 0.7e very low readout noise.
128MB DDR Buffer
No one want to lost frame at long exposure capturing. As the member of QHYCCD high pixel cmos camera, QHY163M/C has the build-in 128MB DDRII image buffer. This buffer has great helping for big image transfer and prevents the frame lost under long exposure. This buffer also makes the smoothly running on some low speed computer or on the USB2.0 port.
Fully Anti-Dew Solution
With more than ten years experience on cooled CCD camera design. QHYCCD applied the fully anti-dew technology to the QHY163 including the fully air proof CMOS chamber with silicon gel tube socket and the CMOS window heater. With these technology you doe not need worry about the dew form on both CMOS sensor and the optic windows, even in a high humidity environment.
