The ICX406 is a 3.98-megapixel CMOS image sensor manufactured by Sony. It delivers a 2312 × 1720 pixel array with a 3.125 µm pixel pitch, providing efficient photon collection at each photosite. The optical format spans a 9.005 mm diagonal with a 289:215 aspect ratio, typical of the 1/2-inch optical class used in compact industrial cameras. With 3.125 µm pixels, the sensor features compact pixel pitch suited for high-resolution imaging in space-constrained camera designs.
