ABSTRACT:
An optical structural element has a substrate and includes at least one wear protection system built up of one or several layers on the substrate. The layers are of at least one of the materials ZrO.sub.2, AlN,(Al,Cr).sub.2 O.sub.3, BN and diamond. A total thickness of the layers is more than about 100 nm and the mean transmission of the wear protection system is at least 10% in a spectral band of 10 nm within the visible light spectrum.
