Characterization of surface qualities of polished optical glass by ellipsometric way

摘要

Ellipsometry is a technique of surfaces analysis, founded on the measure of light polarization state after reflection on a plane surface. Work consists in characterizing the surface quality of polished optical glass by ellipsometry. The measured ellipsometric parameters enabled us to lead to a correlation with roughness while being based on the theory of Maxwell-Garnett to determine the optical properties of the effective milieu.
