The IMX557 is a 12.19-megapixel CMOS image sensor manufactured by Sony. It delivers a 4032 × 3024 pixel array with a 1.8 µm pixel pitch, providing efficient photon collection at each photosite. The optical format spans a 9.072 mm diagonal with a 0.16875 aspect ratio, typical of the 1/2-inch optical class used in compact industrial cameras. With 1.8 µm pixels, the sensor features very fine pixel pitch targeting maximum spatial resolution in microscopy and metrology systems.
