Brand: QHYCCD / SKU: QHY-110058
The QHY268M/C is a new generation of back-illuminated CMOS cameras with true 16-bit A/D and 3.76um pixels. This Sony sensor is an ideal CMOS sensor exhibiting no amplifier glow. 16-bit A/D gives high resolution sampling of the whole full well range. Digitizing 0-65535 levels yields a smooth image with continuous gradation of grayscale levels.
