Abstract
Exotic Electro-Optics recently conducted a basic evaluation of state-of-the-art spinel material from the standpoint of optical fabrication. The goal of this study was to characterize the behavior of several spinel samples as they passed through a complete optical fabrication sequence. Overall, the material was found to be compatible with conventional fabrication processes. Methodologies used in the manufacture of heritage optical components were employed successfully, without significant modification, in the fabrication of the spinel windows. A standard anti-reflective coating was used to coat polished spinel samples. Good coating-to-substrate adhesion was observed and the coated optic exhibited the expected spectral performance. In this paper, Exotic Electro-Optics reports on the results of this work.
