Method for producing a reflection-reducing interference layer system and reflection-reducing interference layer system

摘要

The method involves forming a stack of layers (3), and applying the stack of layers to a surface of a substrate (1) i.e. glass substrate, which includes alternative high refractive index and a low refractive index. A nano-porous final layer (4) is applied to the stack of layers by vapor deposition of the material of a lower layer of the stack of layers at an oblique angle relative to a normal of an upper layer of the stack of layers such that the refractive index of the lower layer is lower than the refractive index of the upper layer of the stack of layers. The stack of layers is made of non-organic materials. Independent claims are also included for the following: (1) a reflection-reducing interference layer system (2) an optical element.
