The IMX503 (Pregius) is a 4.07-megapixel monochrome CMOS image sensor manufactured by Sony. It delivers a 2360 × 1726 pixel array with a 4.8 µm pixel pitch, providing efficient photon collection at each photosite. The optical format spans a 14.034 mm diagonal with a 1180:863 aspect ratio, matching the 2/3-inch optical format common in professional machine vision cameras. With 4.8 µm pixels, the sensor features compact pixel pitch suited for high-resolution imaging in space-constrained camera designs.
