The AR0333 is a 3.15-megapixel CMOS image sensor manufactured by On Semi. It delivers a 2048 × 1536 pixel array with a 2.2 µm pixel pitch, providing efficient photon collection at each photosite. The optical format spans a 5.632 mm diagonal with a 0.16875 aspect ratio, in the 1/4-inch class found in compact embedded vision modules. With 2.2 µm pixels, the sensor features very fine pixel pitch targeting maximum spatial resolution in microscopy and metrology systems.
