Abstract
An environmentally stable silver mirror having very high reflection values over a large spectral range comprises a silver layer disposed on a substrate, which is covered by a zinc sulfide layer. So that the sulphur 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 layer and the zinc sulfide layer.
