Thickness of thin films on glass - a round robin test : Report of the International Commission on Glass (ICG) Technical Committee 19 "Glass Surface Diagnostics"

Abstract

The film thicknesses of five different layer Systems on glass Substrates were analyzed and determined in a multi-method approach by eight different university and industrial laboratories. The total coating thicknesses varied between a few nm up to some 100 nm. The measurements give information about the chemical composition and cover a wide spectrum of typical coating application on glasses. The results of the different laboratories and methods are compared and the challenges and limits of the various analytical techniques are discussed.
