The OV32B PureCel Plus-S is a 31.96-megapixel CMOS image sensor manufactured by OmniVision Technologies. It delivers a 6528 × 4896 pixel array with a 0.702 µm pixel pitch, providing efficient photon collection at each photosite. The optical format spans a 5.728 mm diagonal with a 0.16875 aspect ratio, in the 1/4-inch class found in compact embedded vision modules. With 0.702 µm pixels, the sensor features very fine pixel pitch targeting maximum spatial resolution in microscopy and metrology systems.
