Abstract
An environmentally stable silver containing mirror having very high reflection values over a large spectral range comprises a silver containing layer disposed on a substrate, which is covered by a zinc sulfide layer. So that the sulfur being set free during the application or during the vaporization of the zinc sulfide to be applied, does not attack the silver, at least one barrier or intermediate layer is placed between the silver containing layer and the zinc sulfide layer.
