The AR0432 is a 4.04-megapixel CMOS image sensor manufactured by On Semi. It delivers a 2316 × 1746 pixel array with a 2 µm pixel pitch, providing efficient photon collection at each photosite. The optical format spans a 5.801 mm diagonal with a 386:291 aspect ratio, in the 1/4-inch class found in compact embedded vision modules. With 2 µm pixels, the sensor features very fine pixel pitch targeting maximum spatial resolution in microscopy and metrology systems.
