Reflektor med resistent overflate

摘要

A reflector has a reflection layer sequence with a silicon oxide or aluminum oxide surface layer that protects the underlying layers and is resistant to wiping. A mechanically resistant reflector, with high total reflection, comprises a reflector body bearing a functional coating and a reflection layer sequence including a reflective layer and one or more transparent layers, the reflection layer sequence includes a≥3 nm thick SiOx (x = 1.1 to 2.0) or Al2O3 protective surface layer which protects the underlying layers against mechanical damage and which exhibits no damage after 50 test cycles of 100 wiping strokes in the wiping test of DIN 58196.
