Patent ID: 7169441

Claim:
A method for coating a transparent substrate with a coating system, comprising: performing a dip or spin method of sol-gel techniques to deposit at least five individual layers on the transparent substrate, wherein consecutive layers of the five individual layers have different indices of refraction and the five individual layers have UV and temperature-stable inorganic materials, wherein the five individual layers have the following structure: substrate/M 1 /T 1 /M 2 /T 2 /S, wherein substrate designates the transparent substrate, M 1 , M 2 denote layers with intermediate index of refraction, T 1 , T 2 denote layers with high index of refraction, S denotes a layer with low index of refraction, and for a reference wavelength of 550 nm the indices of refraction of the individual layers lie in the following range: n low ≦1.6;1.6<n intermediate <1.8; and 1.9 ≦n high , and the thickness of the individual layers lies in the following range: for the layer M 1 : 70 nm≦d M1 ≦100 nm for the layer T 1 : 30 nm≦d T1 ≦70 nm for the layer M 2 : 20 nm≦d M2 ≦40 nm for the layer T 2 : 30 nm≦d T2 ≦50 nm for the layer S: 90 nm≦d S ≦110 nm.
