The AR0820 is a 8.29-megapixel CMOS image sensor manufactured by On Semi. It delivers a 3840 × 2160 pixel array with a 2.1 µm pixel pitch, providing efficient photon collection at each photosite. The optical format spans a 9.252 mm diagonal with a 0.672916667 aspect ratio, typical of the 1/2-inch optical class used in compact industrial cameras. With 2.1 µm pixels, the sensor features very fine pixel pitch targeting maximum spatial resolution in microscopy and metrology systems.
