The HM0357 is a 0.31-megapixel CMOS image sensor manufactured by Himax Technologies. It delivers a 640 × 480 pixel array with a 2 µm pixel pitch, providing efficient photon collection at each photosite. The optical format spans a 1.6 mm diagonal with a 0.16875 aspect ratio. With 2 µm pixels, the sensor features very fine pixel pitch targeting maximum spatial resolution in microscopy and metrology systems.
