For ground- and spaced based applications, Ag coated reflectors are indispensable because of their high reflectivity. The transport, assembling and storage of these reflectors takes a long time, before they are finally commissioned for the actual app

Time durability and environmental stability of silver-coated glass mirrors improve if silver layer is protected by a transparent thin film coating. The choice of the protecting layer material and of the methods for mirror manufacturing influences the

High-reflective coatings are indispensable in order to manufacture mirrors with highest possible reflectivity. The maximum reflectivity can be achieved by all-dielectric coatings; however, the spectral bandwidth of these mirrors is limited. For astro

The optical properties of opaque sputtered silver films are investigated and related to their surface morphology. As reference, an evaporated sample produced by thermal flash evaporation has been studied, too. Standard optical and electrical characte

H2S and particles from the atmosphere can damage silver reflectors. These defects lead to scattering and a reduction of reflectivity. With regard to these risks, the suitability of sputtered SiO2, Al2O3, and SiO2-Al2O3 nanolaminates for the protectio

Fur die Bestimmung der optischen Konstanten von Substraten und auch Einzelschichten im nahen- und mittleren Infrarot wurde eine Vorgehensweise entwickelt, die auch bei verschwindendem Transmissionssignal noch eine konsistente Spektrenauswertung zulas

Es gibt verschiedene Moglichkeiten, achromatische Strahlteiler (Neutralteiler) mittels dunner Schichten zu realisieren. Ob die Wahl dabei auf einen metallischen, einen dielektrischen oder einen metall-dielektrischen Strahlteiler fallt, hangt im Wesen

In order to manufacture mirrors metal based coatings (Al, Au and Ag) are applied, as they enable a high reflectivity and at the same time a broad spectral bandwidth. Of all metals, Ag provides the highest reflectivity from VIS to IR. Silver is a nobl
