II-VI Infrared Expands Durable Coatings with New Thin Film Diamond OverCoat

II‐VI Incorporated’s (NASDAQ:IIVI) Infrared Division, a world leader in laser optics, announced the expansion of its durable coatings with a new thin film Diamond OverCoat (DOC). Applications such as 3D printing and via hole drilling expose CO₂ laser optics to harsh environments and DOC is a hybrid anti-reflection (AR) coating, that minimizes tradeoffs between optical performance and durability, compared to standard AR designs or existing diamond-like carbon (DLC) coatings.

As quoted in the press release:

“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,” said John Ryan, Vice President of Sales, II-VI Laser Solutions. “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 various geometries, wavelengths and materials including ZnSe, copper, silicon, SiC and diamond.
