Abstract
An optical element can include a substrate comprising a Group VIA or fluoride-based non-oxide material and an adhesion layer disposed directly on the substrate. An anti-reflective coating stack is disposed directly on the adhesion layer. Methods for forming an optical element are also provided. The density and stress of the adhesion layer and layers of the anti-reflective coating stack are controlled to provide corrosion-resistant coatings on Group VIA or fluoride-based non-oxide substrates. Preferred substrate materials are materials that exhibit high transparency in the infrared.
