The HWK4123 is a 9.42-megapixel NIR/C image sensor manufactured by Fairchild Imaging (BAE Systems). It delivers a 4096 × 2300 pixel array with a 4.6 µm pixel pitch, providing efficient photon collection at each photosite. The optical format spans a 21.609 mm diagonal with a 1024:575 aspect ratio, corresponding to the 1-inch optical class used in industrial and broadcast cameras. With 4.6 µm pixels, the sensor features compact pixel pitch suited for high-resolution imaging in space-constrained camera designs.
