Optical coatings are an integral part of superior optical components. Astronomical applications (ground- and space-based)
place especially high demands on these coatings, not only with regard to their optical performance but also to
their mechanical and environmental stability, their thermal properties, and their radiation resistance. This article presents
a short overview of several coating solutions developed in recent years at Fraunhofer IOF in order to meet the
challenging demands of astronomical applications. The focus is placed on high reflective coatings for different
wavelength regions including coatings for the VUV range below 100nm, coatings for the DUV wavelength range above
100nm and VIS/NIR/IR coatings. Further, amorphous silicon layers will be introduced which can be polished to very
low roughness values and therefore can act as polishing layer for the manufacture of ultraprecise optical components
from metal substrates.© (2012) COPYRIGHT Society of Photo-Optical Instrumentation Engineers (SPIE). Downloading of the abstract is permitted for personal use only.
