The GC0307 is a 0.32-megapixel CMOS image sensor manufactured by Galaxycore Microelectronics. It delivers a 648 × 488 pixel array with a 5.15 µm pixel pitch, providing efficient photon collection at each photosite. The optical format spans a 4.178 mm diagonal with a 81:61 aspect ratio, in the 1/4-inch class found in compact embedded vision modules. With 5.15 µm pixels, the sensor features mid-range pixel pitch balancing sensitivity and resolution for industrial inspection and machine vision.
