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.

QHY163M/C

Cooled USB 3.0 Planetary and Deep Sky COLDMOS Camera

The QHY163M/C camera is an incredible value.

It uses a relatively large 4/3inch, 16 Megapixel CMOS sensor, available in monochrome.

The QHY163M/C has exceptionally low readout noise (as low as 1 electron!), low dark current and

two-stage cooling capable of reducing the sensor temperature to -40C below ambient.

The sensor chamber is sealed and the optical window is heated to prevent dew.

The camera's interface is USB 3.0 and delivers 23FPS@16 megapixel full resolution output,

30FPS@4K HD video output.

128MB DDR Buffer

The QHY163 has a built-in 128MB DDRII image buffer.

The benefit of the image 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.

Full Anti-Dew Solution

With more than a decade of experience designing cooled cameras, QHYCCD has applied this knowledge

to the QHY163 camera. The full anti-dew technology includes a sealed CMOS chamber with silicon gel tube

socket and a heated chamber optical window. This technology prevents dew from forming on the

sensor itself, or on the chamber window, even in a high humidity environment.
