Anti-reflection optical multilayer coating

摘要

An optical multilayer coating, exhibiting wide band especially high anti-reflection and light transmission or especially high anti-reflection at a given light transmission, comprises a layer stack of high and low refractive index layers, at least two high refractive index layers being immediately adjacent one another. Also claimed is a method of producing the above coating, in which the individual layers are produced by cathodic sputtering, especially reactive sputter deposition.
