OPTICAL SYSTEM
First Claim
1. An optical system comprising a substrate and disposed on said substrate a replica layer, characterized in that a functionality selected from the group consisting of grating, volume Bragg grating, holographic, diffractive, non-periodic structure, optical filter, polarizer, micro lens and gradient index lens is incorporated in the substrate.

Abstract
An optical system comprising a substrate and disposed on said substrate a replica layer, characterised in that a functionality selected from the group consisting of grating, volume Bragg grating, holographic, diffractive, non-periodic structure, optical polarizer, micro lens and gradient index lens is incorporated in the substrate. The object of the present invention is therefore to provide an optical system in which elements which previously played a passive part are given an active role in order to thus realise desired properties of the optical system.

- 12. A method for manufacturing an optical system comprising a substrate of glass and a polymeric replica layer disposed thereon, characterized in that a substrate, in which a functionality selected from the group consisting of grating, volume Bragg grating, holographic, diffractive, non-periodic structure, optical filter, polarizer, micro lens and gradient index lens is already implemented, is processed in such a manner that a substrate configured as a lens is obtained, whereupon the replica layer is replicated on the lens substrate thus obtained.

13. A method for manufacturing an optical system comprising a glass substrate and a polymeric replica layer disposed thereon, characterized in that a surface layer of the substrate is processed so that a functionality is incorporated, which functionality is selected from the group consisting of grating, volume Bragg grating, holographic, diffractive, non-periodic structure, optical filter, polarizer, micro lens and gradient index lens, after which a polymeric layer is replicated on the thus processed surface layer, in such a manner that the replication layer thus obtained is configured as a lens.
