The ISOCELL CT3 is a 21.15-megapixel CMOS image sensor manufactured by Samsung Semiconductors. It delivers a 5504 × 3842 pixel array with a 4.25 µm pixel pitch, providing efficient photon collection at each photosite. The optical format spans a 28.527 mm diagonal with a 2752:1921 aspect ratio, suitable for medium-format and high-end machine vision systems. With 4.25 µm pixels, the sensor features compact pixel pitch suited for high-resolution imaging in space-constrained camera designs.
