Product description
The QHY268C is a cooled, back-illuminated, 26 megapixel color CMOS camera based on the Sony IMX571 sensor with native 16-bit A/D and 3.76um pixels. The BFL of QHY268C is 12.5mm under a new front design.
The Sony IMX571 sensor has on-chip 16-bit A/D for highest resolution of greyscale. The output is real 16-bits with 65536 levels. Compared to 12-bit and 14-bit A/D, 16-bits provides higher sampling resolution. At high gain, the camera yields close to 1e-/ADU with no sample error and low read noise.
The back-illuminated Sony Exmor sensor has about twice the QE of similar front illuminated sensors. The QHY268C has zero amplifer glow.
