QHYCCD Small Size COLDMOS Cameras

The QHYCCD small size COLDMOS camera series includes all of our cooled cameras with BSI (back-illuminated) and FSI (front-illuminated) CMOS sensors in sizes smaller than 1 inch. 


No one wants to lose a frame in a long exposure.  QHY178, QHY290, and QHY224 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.

The QHY174 COLDMOS camera is available in two versions, the standard version and the GPS version. The GPS version has a built-in GPS module to mark time information with high precision (up to 1 micro-second) in the image header.  The QHY174-GPS is the world's first GPS pps based high precision hardware timestamping camera.  It is ideally suited for occultation timing, transit timing, real time 3D meteor capture, satellite 3D tracing, unmanned aerial vehicle 3D tracing, etc.
