Abstract:
A mirror, in particular for a microlithographic projection exposure apparatus, has an optically effective surface, a mirror substrate ( 205, 305 ), a reflection layer ( 220, 320 ), which is configured to provide the mirror with a reflectivity of at least 50% for electromagnetic radiation with a predetermined operating wavelength incident on the optically effective surface ( 200 a,  300 a ) at angles of incidence in relation to the respective surface normals of at least 65°, and a substrate protection layer ( 210, 310 ) which is arranged between the mirror substrate ( 205, 305 ) and the reflection layer ( 220, 320 ). The substrate protection layer has a transmission of less than 0.1% for EUV radiation.

Claim (Index 7):
The optical system as claimed in  claim 1 , wherein the substrate protection layer has a multilayer system comprising a plurality of individual layers.
