The ISOCELL 6A3 is a 1.99-megapixel CMOS image sensor manufactured by Samsung Semiconductors. It delivers a 1412 × 1412 pixel array with a 1.75 µm pixel pitch, providing efficient photon collection at each photosite. The optical format spans a 3.495 mm diagonal with a 0.042361111 aspect ratio. With 1.75 µm pixels, the sensor features very fine pixel pitch targeting maximum spatial resolution in microscopy and metrology systems.
