The AR0138 is a 1.23-megapixel RCCC image sensor manufactured by On Semi. It delivers a 1280 × 960 pixel array with a 4.2 µm pixel pitch, providing efficient photon collection at each photosite. The optical format spans a 6.72 mm diagonal with a 0.16875 aspect ratio, characteristic of 1/3-inch sensors widely used in embedded and surveillance systems. With 4.2 µm pixels, the sensor features compact pixel pitch suited for high-resolution imaging in space-constrained camera designs.
