Paper Abstract

The materials applied to infra-red window materials in the form of thin coatings for mechanical protection or for optical reasons, can often only be produced in that form. This means that characterizing the mechanical properties of these materials requires very specialized techniques. A range of such techniques have been developed at the Cavendish Laboratory for determining the thermal expansion coefficient, internal stress, thermal shock resistance, hardness, and Young's modulus as a function of temperature of such films and results from these experiments are given.
