Coating DLC on Chalcogenides
When it comes to infrared optics, chalcogenides offer many advantages that legacy materials such as silicon, germanium, and zinc selenide simply cannot match. However, given their susceptibility to scratches and other surface-layer defects, chalcogenides demand an extremely durable, protective coating so the optic can withstand the harshest environmental conditions. Put simply, only a virtually indestructible diamond-like carbon (DLC) coating will do. And herein lies a key challenge; because coating chalcogenides with DLC has been notoriously challenging and plagued by adhesion problems and coating defects. Until now.
