Abstract:
In order to make possible both good laser resistance and good antireflection properties, an optical element, in particular for UV lithography, comprising a substrate and a coating on the substrate having at least four layers, is proposed, wherein a first layer comprising a low refractive index inorganic fluoride compound is arranged on the substrate, a layer comprising an inorganic oxide-containing compound is arranged as a layer the most distant from the substrate, and at least two further layers each comprising an inorganic fluoride compound or an inorganic oxide-containing compound are arranged alternately between the first and the most distant layers.

Claim (Index 25):
The optical element of  claim 19 , wherein the inorganic fluoride of the first layer comprises at least one material selected from the group consisting of aluminum fluoride, magnesium fluoride, lithium fluoride, sodium fluoride, yttrium fluoride, strontium fluoride, and barium fluoride.
