The S13499 is a 0.33-megapixel monochrome CMOS image sensor manufactured by Hamamatsu Photonics. It delivers a 659 × 494 pixel array with a 9.9 µm pixel pitch, providing efficient photon collection at each photosite. The optical format spans a 8.154 mm diagonal with a 659:494 aspect ratio, typical of the 1/2-inch optical class used in compact industrial cameras. With 9.9 µm pixels, the sensor features mid-range pixel pitch balancing sensitivity and resolution for industrial inspection and machine vision.
