Claims
- 1. A reflection reducing coating on a substrate which is formed from an alternating change layer system of different layer materials each having a lower and higher refractive index, wherein the sum of the layer thicknesses of layers having a higher refractive index is ≦5% of the total layer thickness of the coating, and said layers of the material having a higher refractive index within the layer sequence of said change layer system are uniformly distributed.
- 2. A reflection reducing coating according to claim 1, wherein said coating is deposited on an optically translucent substrate.
- 3. A reflection reducing coating according to claim 1, wherein said substrate consists of a synthetic material or a temperature sensitive crystal material.
- 4. A reflection reducing coating according to claim 1, wherein said layer material having a higher refractive index is selected from oxides or fluorides of the IVth and Vth class B elements.
- 5. A reflection reducing coating according to claim 4, wherein said layer material for the layers having a higher refractive index are Ta2O5, ZrO2, HfO2, TiO2 or indium tin oxide.
- 6. A reflection reducing coating according to claim 1, wherein said SiO2 is a layer material for said layers having a lower refractive index.
- 7. A reflection reducing coating according to claim 1, wherein said MgF2 is a layer material for the layers having a lower refractive index.
- 8. A reflection reducing coating according to claim 1, wherein said layer forming the boundary layer towards the air is formed from a material having a lower refractive index.
- 9. A reflection reducing coating according to claim 1, wherein layers of different materials having a higher refractive index are arranged in said layer system.
- 10. A reflection reducing coating according to claim 1, wherein said layer system is matched to a predeterminable wavelength range of light.
- 11. A reflection reducing coating according to claim 1, wherein at least five individual layers form said layer system.
- 12. A reflection reducing coating according to claim 1, wherein said coating has a total thickness between 500 and 2500 nm.
- 13. A reflection reducing coating according to claim 1, wherein said substrate is an optical or opto-electronic element.
- 14. A reflection reducing coating according to claim 1, wherein said substrate is a spectacle glass.
