A military contractor enlisted Resolve Optics to develop a lens that provides a comprehensive 360° view, enabling the system to detect UV emissions from muzzle flashes, pinpoint their locations, and respond automatically.
The contractor's automated return fire system was designed to incorporate eight identically mounted, AR-coated UV lenses with a diameter of 10.5 mm, working alongside a solar blind filter stack with an operational bandwidth of 240 to 280 nm. This ruggedly built, specialist f2.8 lens offered high-resolution UV imaging from distances of 10 meters to infinity, ensuring minimal distortion.
