The ISOCELL 3M3 is a 13.13-megapixel CMOS image sensor manufactured by Samsung Semiconductors. It delivers a 4208 × 3120 pixel array with a 1 µm pixel pitch, providing efficient photon collection at each photosite. The optical format spans a 5.238 mm diagonal with a 263:195 aspect ratio, in the 1/4-inch class found in compact embedded vision modules. With 1 µm pixels, the sensor features very fine pixel pitch targeting maximum spatial resolution in microscopy and metrology systems.
