QHYCCD Medium Size COLDMOS Cameras
The QHYCCD medium size COLDMOS camera series includes all of our cooled cameras with sensor sizes from 1 inch to Full Frame (35mm Format) and includes BSI (back-illuminated) and FSI (front-illuminated) CMOS sensors.
No one wants to lose a frame in a long exposure. All of the QHY medium size COLDMOS cameras have a built-in 128MB DDRII image buffer. The benefit of the image buffer, compared to a camera without the buffer, is that the memory will cache the image and transfer it to the computer when the USB interface is not busy or being interrupted, and the frame will not be lost or corrupted. This buffer also allows a slower computer with USB 2.0 socket to capture every frame without loss even if the USB socket is occasionally busy with other peripherals. This buffer also helps multiple camera applications and avoids USB transfer problems. For example, it is possible to operate four QHY163M cameras on the same computer to create an LRGB imaging array.
