Abstract
Ziel der Erfindung ist es, ein hinsichtlich der optischen Eigenschaften auf unebenen Oberflächen möglichst unempfindliches Antireflex-System bereit zu stellen Dazu ist ein Verfahren zur Herstellung eines transparentes Element (1) vorgesehen, wobei das transparente Element (1) umfasst ein transparentes Substrat (3) und auf diesem Substrat (3), eine mehrlagige Antireflex-Beschichtung (5), welche zumindest sechs Lagen umfasst, wobei sich Lagen (51, 53, 55) mit hohem Brechungsindex mit Lagen (50, 52, 54, 56) mit niedrigerem Brechungsindex abwechseln, und wobei die Lagen (51, 53, 55) mit höherem Brechungsindex eine größere Härte als die Lagen (50, 52, 54, 56) mit niedrigerem Brechungsindex aufweisen, und wobei die oberste Lage (60) der mehrlagigen Antireflex-Beschichtung (5) eine Lage mit niedrigerem Brechungsindex ist, und wobei das Substrat (3) zumindest zwei Oberflächenbereiche (30, 32) aufweist, die sich hinsichtlich ihrer Neigung unterscheiden, wobei die Antireflex-Beschichtung (5) die Oberflächenbereiche (30, 32) unterschiedlicher Neigung bedeckt, und wobei für die Antireflex-Beschichtung (5) auf den Oberflächenbereichen (30, 32) zumindest eines der folgenden Merkmale gilt die Farben der Restreflexion jeweils unter 0° Einfallswinkel auf die Oberflächenbereiche (30, 32) unterscheiden sich im CIE xyz-Farbsystem voneinander um nicht mehr als Δx=0 05, Δy=0 05, bevorzugt nicht mehr als Δx=0 03, Δy=0 03, besonders bevorzugt um nicht mehr als Δx=0 02, Δy=0 02, die photopischen Reflektivitäten unter 0° Einfallswinkel der Oberflächenbereiche (30, 32) unterscheiden sich voneinander um nicht mehr als ΔR_ph=1 5%The aim of the invention is to provide an antireflection system that is as insensitive as possible with regard to the optical properties on uneven surfaces. For this purpose, a method for producing a transparent element (1) is provided, the transparent element (1) comprising a transparent substrate (3) and on this substrate (3), a multi-layer anti-reflection coating (5) comprising at least six layers, layers (51, 53, 55) with a high refractive index and layers (50, 52, 54, 56) with a lower refractive index alternate, and wherein the layers (51, 53, 55) with a higher refractive index have a greater hardness than the layers (50, 52, 54, 56) with a lower refractive index, and wherein the top layer (60) of the multilayer anti-reflective coating ( 5) a layer with a lower refractive index, and wherein the substrate (3) has at least two surface areas (30, 32) which differ in terms of their inclination, wherein the anti-reflective coating (5) the Surface areas (30, 32) with different inclinations are covered, and at least one of the following features applies to the anti-reflective coating (5) on the surface areas (30, 32): the colors of the residual reflection each at an angle of incidence of 0° on the surface areas (30, 32 ) differ from each other in the CIE xyz color system by no more than Δx=0 05, Δy=0 05, preferably no more than Δx=0 03, Δy=0 03, particularly preferably by no more than Δx=0 02, Δy= 0 02, the photopic reflectivities at 0° angle of incidence of the surface areas (30, 32) differ from each other by no more than ΔR_ph=1 5%
