The OV20381 HDRPureCel Plus-S is a 20.16-megapixel CMOS image sensor manufactured by OmniVision Technologies. It delivers a 5184 × 3888 pixel array with a 1 µm pixel pitch, providing efficient photon collection at each photosite. The optical format spans a 6.48 mm diagonal with a 0.16875 aspect ratio, characteristic of 1/3-inch sensors widely used in embedded and surveillance systems. With 1 µm pixels, the sensor features very fine pixel pitch targeting maximum spatial resolution in microscopy and metrology systems.
