The ISOCELL 6A1G is a 1.31-megapixel CMOS image sensor manufactured by Samsung Semiconductors. It delivers a 1280 × 1024 pixel array with a 1.75 µm pixel pitch, providing efficient photon collection at each photosite. The optical format spans a 2.869 mm diagonal with a 0.211111111 aspect ratio. With 1.75 µm pixels, the sensor features very fine pixel pitch targeting maximum spatial resolution in microscopy and metrology systems.
