The AR0522 is a 5.04-megapixel NIR image sensor manufactured by On Semi. It delivers a 2592 × 1944 pixel array with a 2.2 µm pixel pitch, providing efficient photon collection at each photosite. The optical format spans a 7.128 mm diagonal with a 0.16875 aspect ratio, characteristic of 1/3-inch sensors widely used in embedded and surveillance systems. With 2.2 µm pixels, the sensor features very fine pixel pitch targeting maximum spatial resolution in microscopy and metrology systems.
