Abstract:
The disclosure relates to an optical element, in particular for a microlithographic projection exposure apparatus. The optical element has an optical effective surface. The optical element includes a substrate, a layer system that is present on the substrate, and a protective cover extending over an edge region of the optical element that is adjacent to the optical effective surface. During operation of the optical element, the protective coating reduces an ingress of hydrogen radicals into the layer system in comparison with an analogous design without the protective cover, wherein a gap is formed between the protective cover and the layer system.

Claim (Index 18):
An optical element, comprising:\n an optical effective surface, comprising:\n a substrate; \n a layer system supported by the substrate; and \n a protective cover configured to inhibit ingress of hydrogen radicals into the layer system, \n wherein:\n the protective cover extends over an edge region of the optical element; \n the edge region is adjacent to the optical effective surface; and \n the protective cover comprises a material comprising at least one member selected from the group consisting of copper, silver, gold, nickel, cobalt, chromium and vanadium.
