The MT9D001 is a 1.92-megapixel CMOS image sensor manufactured by On Semi (Micron, Aptina). It delivers a 1600 × 1200 pixel array with a 4.2 µm pixel pitch, providing efficient photon collection at each photosite. The optical format spans a 8.4 mm diagonal with a 0.16875 aspect ratio, typical of the 1/2-inch optical class used in compact industrial cameras. With 4.2 µm pixels, the sensor features compact pixel pitch suited for high-resolution imaging in space-constrained camera designs.
