Abstract

Adhesion and strain are two important physical properties which determine the success or failure of thin-film coatings in optical applications. In this paper we describe the design and operation of a dynamically loaded scratch tester for making measurements of relative adhesive strength, and a modulated transmission ellipsometer for measuring total and internal strain. Numerous examples for coating/substrate systems of interest to optical applications are given.
