COATED OPTICAL OBJECT AND METHOD FOR PRODUCING A COATED OPTICAL OBJECT

摘要

The invention relates to a coated object (100) which comprises a substrate (1) and an optical coating (2) arranged on the substrate (1). The optical coating (2) has a reflection-reducing layer sequence (3) which comprises a cover layer (4) with a refractive index nA and at least one diamond layer (5) with a refractive index nD1> nA. The diamond layer (5) is arranged between the cover layer (4) and the substrate (1) and has diamond crystals or consists thereof, said diamond layer (4) having a thickness of less than 500 nm.
