The DR4K3.5 is a 0.01-megapixel monochrome CMOS image sensor manufactured by AMS (Awaiba). It delivers a 4096 × 3 pixel array with a 3.5 µm pixel pitch, providing efficient photon collection at each photosite. The optical format spans a 14.336 mm diagonal with a 170.66875 aspect ratio, matching the 2/3-inch optical format common in professional machine vision cameras. With 3.5 µm pixels, the sensor features compact pixel pitch suited for high-resolution imaging in space-constrained camera designs.
