摘要:
A catadioptric lens includes at least two optical elements arranged along an optical axis. Both optical elements are configured as a mirror having a substrate and a highly reflective coating applied to an interface of the substrate. The highly reflective coating extends from the interface of the substrate along a surface normal. At least one of the highly reflective coatings has one or a plurality of layers. The optical total layer thickness of the one layer of the plurality of layers increases radially from the inner area outward.
