The OV16A1Q is a 13.25-megapixel CMOS image sensor manufactured by OmniVision Technologies. It delivers a 4224 × 3136 pixel array with a 1 µm pixel pitch, providing efficient photon collection at each photosite. The optical format spans a 5.261 mm diagonal with a 2.784027778 aspect ratio, in the 1/4-inch class found in compact embedded vision modules. With 1 µm pixels, the sensor features very fine pixel pitch targeting maximum spatial resolution in microscopy and metrology systems.
