QHY 268 MONO APS-C

Price 2 599,00 €

The QHY268M is a cooled, back-illuminated, 26 megapixel CMOS camera based on the Sony IMX571 sensor with native 16-bit A/D and 3.76um pixels. The BFL of QHY268M 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 QHY268M has zero amplifer glow.

Back Focal Length*QHY268C: 17.5mm (without CAA)
This intercept does not include CAA. If CAA is used, it increases by 6mm (23.5mm total). Please check the mechanical drawing below for details.

QHY268M: 12.5mm (with CAA)
If used with the QHY filter wheel, the actual calculated intercept is 12.5mm. The actual BFL (the intercept from the CMOS chip to the top of the camera) is 14.5mm. Since most uses will match CFW with monochrome cams, please take 12.5mm as major reference. Check the mechanical drawing below for details.
