Abstract

<abstract abstract-type="main" xml:lang="en"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>UV‐enhanced Ag‐coatings with optimized environmental stability</bold> </p> <p>For the construction of optical instruments, mirrors with silver (Ag) coatings are of great importance, because Ag has the highest reflectivity of all metals from the visible (VIS) throughout the infrared (IR) spectral range. Investigations performed at IOF show, that the deposition of a closed and dense protective layer is a necessary but not a sufficient condition for the effective protection of silver: hygroscopic particles can harm even silver coatings protected by a previously defect‐free protective layer. In order to improve the protection, a nanolaminate approach for Ag‐protection has been developed. By this approach, both the environmental stability and the optical performance can be optimized.</p> </abstract>
