A Computer Code for Modeling Optical Properties of Materials II

A 1989 SPIE proceedings paper described the first version of an optical properties computer code developed at the Applied Physics Laboratory. The emphasis was on durable infrared window materials. In the thirty years since the beginning of this code development a lot of progress has been made concerning the physics based models used to represent the complex index of refraction and the number of materials characterized. A key feature is providing the frequency and temperature dependence of optical properties. Room temperature data is available for a wide range of materials, but temperature dependent data is much harder to find. The status of the code development along with example outputs will be reported.
