METHOD FOR PRODUCING REFLECTION-REDUCING INTERFERENCE LAYER SYSTEM, AND REFLECTION-REDUCING INTERFERENCE LAYER SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a method for producing a reflection-reducing interference layer system with improved anti-reflection properties.SOLUTION: A stack of layers is formed by applying to a surface of a substrate 1 several layers which alternately includes a high refractive index layer 6, 8 and a low refractive index layer 5, 7. A nanoporous final layer 4 is applied to the stack of layers by vapor deposition of the material of the final layer 4 at an oblique angle relative to the normal of the top layer 8 of the stack of layers such that the refractive index of the final layer 4 is lower than the refractive index of the top layer 8 of the stack of layers.
