II-VI Infrared Launches New Thin Film Diamond OverCoat

II-VI Incorporated’s II-VI Infrared Division announced the expansion of its durable coatings with a new thin film Diamond OverCoat (DOC). II-VI Incorporated is a world leader in laser optics.  

Applications such as via hole drilling and 3D printing expose CO2 laser optics to harsh environments. The new Diamond OverCoat from II-VI is a hybrid anti-reflection coating that reduces tradeoffs between durability and optical performance compared to basic anti-reflection (AR) designs or currently available diamond-like carbon (DLC) coatings.

Our Diamond OverCoat’s unique spatter resistant design is a good solution for any materials processing where copper spatter or debris may adhere to the optical surface. The combination of a low absorption and high durability coating on zinc selenide optics is an ideal alternative to germanium DLC, in processes where frequent cleaning is required.

The new versatile DOC coating can be applied to numerous wavelengths, geometries, and materials such as copper, ZnSe, SiC, silicon, and diamond.
