Abstract

In this paper the results of a study and the found solutions for some interferential filters obtained through Physical Vapor Deposition method on optical support are presented. These filters have a good resistance to an intense optical radiation, as well a high optical efficiency in a large spectral domain (400 – 2000 nm). Both theoretical and experimental aspects will be discussed herein..
