Patent ID: 7564627

Claim:
A structured optical element containing a substrate of which the surface comprises a first zone and a second zone and the first zone contains a first coating system with an optical function consisting of a first internal partial coating system and a complementary partial coating system, where said first internal partial coating system comprises at least one layer and does not extend over the second zone and said complementary partial coating system comprises at least one layer and extends over the first zone and the second zone and where said complementary partial coating system is, in said second zone, at least part of a second coating system with an optical function that differs from the optical function of said first coating system, where said first internal partial coating system is arranged between said substrate and said complementary partial coating system and said surface of said substrate in said first zone with said first coating system constitutes a first optical filter that is associated with a first wavelength range consisting of one or more wavelength intervals and said surface of said substrate in said second zone with said second coating system constitutes a second optical filter that is associated with a second wavelength range consisting of one or more wavelength intervals and different from said first wavelength range of said first optical filter and said surface of said substrate comprises at least one further zone with at least one further coating system that constitutes at least one further optical filter that is associated with a further wavelength range consisting of one or more wavelength intervals, where one of said wavelength ranges comprises the entire spectrum of visible light and each of the optical filters substantially transmits or reflects light of the wavelength range associated with it and, vice versa, reflects or transmits light of any wavelength range not associated with it, wherein said first zone, said second zone and said further zone are different zones, characterized in that said complementary partial coating system is applied in a single step in all zones without a structuring process and that on said surface of said substrate in at least one of said zones said complementary partial coating system is arranged directly and as only coating system on the substrate and there constitutes a reflection-reducing coating system and that each of said zones is provided with its optical function not until said complementary partial coating system is applied.
