AR coatings are the most extensively employed type of optical thin film.  By reducing the amount of light reflected from a surface, they improve system throughput, increase contrast, and enhance signal-to-noise ratio in virtually every type of optical system.

DSI utilizes three distinct deposition processes to produce AR coatings: evaporation, sputtering and chemical vapor deposition.  This allows us to provide the best solution for your application, not just the one we happen to have available.  And, unlike most other coating companies, DSI can apply efficient AR coatings to highly curved parts, even internal surfaces.  Our complete capabilities span wavelengths from the UV through the long wave IR, and cover a diverse range of substrate materials, including glasses, IR materials, and even patterned coatings (using photolithography) on semiconductor wafers.
