Paper Abstract

A common window material for midwave IR systems is polycrystalline magnesium fluoride. This material is now only available from a French manufacturer, Ceramiques Techniques Desmarquest. The optical constant database on this material is based on samples produced by Kodak and Bausch and Lomb. Because the optical constants are extrinsically dominated in the midwave IR, a new characterization study is needed. The IR absorption coefficient is presented as a function of temperature and frequency. Also, the scatter properties are determined by the bidirectional scatter distribution function.
