Paper Abstract

Optical coatings and surfaces are prepared by a wide variety of processing methods. Since their optical properties are dependent upon both composition and structure, it is often necessary to independently characterize the chemistry of these thin films and surface layers. The ability to measure the composition-depth profile, the impurity content and distribution, and chemical bonding states, can be of great value. These data can be used for understanding the role of the various processing parameters, for quality control and for failure analysis. Of course, many optical coatings and surfaces exhibit unique optical properties which cannot be related directly to their chemical characteristics. In these instances, it may be the microstructure which must be closely examined. Nonetheless, a chemical analysis can be of value if only to verify the absence of compositional or impurity effects.
