Ultra High Resolution

26 mega pixel
APS-C format

QHY268C is a color back illuminated cooled cmos camera with 16bit ADC. 3.76um pixel size, 26mega pixels. QHY268C has only color version.


Native 16BIT ADC
65536 Levels

The QHY268C is the CMOS camera with native 16-bit A/D on-chip. The output is real 16-bits with 65536 levels. To compare with the 12bit and 14bit ADC. The 16bit ADC can get high sample resolution, system gain will be less than 1e/ADU. No sample error noise and low noise.

Great Full Well

51ke- at 3.76um

One benefit of the back-illuminated CMOS structure is improved full well capacity. This is particularly helpful for sensors with small pixels. Even with unbinned 3.76um pixels the QHY268C has a full well capacity of 50ke-

Ultra Low Read Noise

1 to 4 e

The QHY268C has only one electron of read noise at high gain and 15FPS high readout speed. One electron of read noise means the camera can achieve a SNR>3 at only 4 to 6 photons. This is perfect performance when conditions are photon limited, i.e., short exposures, narrow band imaging, etc., making this large area sensor ideal for sky surveys and time domain astronomy.


Electric Rolling Shutter
Low Dark Current

The QHY268C is a back-illuminated Scientific CMOS camera with extremely low dark current using SONY's Exmor BSI CMOS technology.In general, the fan-blade mechanical shutter will be broken if it is used 200,000 times or so, and in some specific cases it is easy to fail to switch on or off. The advantage of electronic shutter over mechanical shutter is high reliability and stability when the observatory shoots a large number of pictures. The electronic shutter is a relatively perfect choice for the observatory.

Best Match for HyerStar System

The round camera case design of QHY268C and the imager size is best match for Hyperstar systems.


USB3.0 interface. 6FPS

TEC Cooling

The QHY268C has regulated TEC Cooling with 2-stage TE Cooler.
