The IMX398 is a 15.93-megapixel CMOS image sensor manufactured by Sony. It delivers a 4608 × 3456 pixel array with a 1.12 µm pixel pitch, providing efficient photon collection at each photosite. The optical format spans a 6.451 mm diagonal with a 0.16875 aspect ratio, characteristic of 1/3-inch sensors widely used in embedded and surveillance systems. With 1.12 µm pixels, the sensor features very fine pixel pitch targeting maximum spatial resolution in microscopy and metrology systems.
