Chemical Vapor Deposition of Multispectral Windows

Abstract

The significance of this research and development program to the Air Force is the demonstrated feasibility of fabricating zinc sulfo-selenide solid solutions for use as multispectral windows. Plates of 2 X 4 X 0.25 in. in size with good transmission properties over the entire spectrum were made and delivered. Furthermore, the strength and hardness of the solid solution is equivalent to zinc sulfide. Some improvement in homogeneity is needed, however, before an engineering material is available for systems use. It was also shown that the hardness of pure zinc selenide could be increased by the use of oxygen or germanium. Finally, the amount of scatter in zinc sulfide was found to be dependent on deposition temperature, deposition rate, zinc usage rate, and the amount of gas phase reaction occurring during deposition.
