The AR0821 is a 8.29-megapixel M/C image sensor manufactured by On Semi. It delivers a 3840 × 2160 pixel array with a 2 µm pixel pitch, providing efficient photon collection at each photosite. The optical format spans a 8.812 mm diagonal with a 0.672916667 aspect ratio, typical of the 1/2-inch optical class used in compact industrial cameras. With 2 µm pixels, the sensor features very fine pixel pitch targeting maximum spatial resolution in microscopy and metrology systems.
