OPTICAL COMPONENT

摘要

PROBLEM TO BE SOLVED: To provide an optical component having excellent weather resistance and showing no decrease in infrared ray transmission characteristics even when used for a long time in a severe environment.SOLUTION: The optical component includes: a substrate comprising a ZnS sintered body; a multilayer intermediate film including two or more types of intermediate layers deposited on a major surface of the substrate; and a surface layer formed of diamond-like carbon deposited on the multilayer intermediate film. The multilayer intermediate film includes an intermediate layer formed of diamond-like carbon.
