Abstract

A reflection-reducing interference layer system is disclosed, which has at least three alternating layers having different refractive indices. At least one nanostructured layer comprising an organic material or an organic-inorganic hybrid material is applied to the alternating layers. With the interference layer system, it is possible to obtain very low reflection over a wide wavelength and incident angle range.
