IR Window Studies
Abstract
This document describes the results of a variety to studies of IR window materials and systems performed at the University of Southern California during 1974-75. The studies fall under three categories: a) IR window material characterization, B) IR window failure mechanisms, and C) window system evaluation. Projects under A include applications of scanning cathodoluminescence microscopy, thin foil transmission electron microscopy, and IR absorption spectroscopy to window materials characterization. Emphasis was on semiconductor materials, including ZnSe, CdTe and GaAs. Measurements of strain optic coefficients were performed on GaAs, and the temperature and frequency dependence of the refractive index of ZnSe was determined precisely. A surface acoustical wave technique for distinguishing between bulk and surface absorption was perfected and applied to uncoated KCl window samples.
