Paper Abstract

The optical property characterization of Spinel and AlON samples, as provided by SURMET, is presented. Several experiments are performed to characterize the optical properties of the materials. A broadband FTIR transmissometer acquired data at temperatures ranging from 298 to 800 K covering a frequency range from 1887 cm-1 to 4000 cm-1. These measurements provided information on the broadband spectral properties of the samples and the temperature dependent shift of the multiphonon band edge. Laser transmission measurements were performed at 632.8 nm and 3.39 mm to provide very accurate transmission values at the two fixed wavelengths. Finally, BSDF measurements on uneroded/eroded sample pairs were performed at 632.8 nm and 3.39 mm. These measurements indicated that the erosion process introduced to these samples would have minimal affect on the imaging performance of the windows in the mid-infrared.
