The AR0238 is a 2.10-megapixel CMOS image sensor manufactured by On Semi. It delivers a 1928 × 1088 pixel array with a 3 µm pixel pitch, providing efficient photon collection at each photosite. The optical format spans a 6.641 mm diagonal with a 241:136 aspect ratio, characteristic of 1/3-inch sensors widely used in embedded and surveillance systems. With 3 µm pixels, the sensor features compact pixel pitch suited for high-resolution imaging in space-constrained camera designs.
