Abstract

The recent trend in infrared optics has been toward higher resolution with wider fields of view, lower weight and size, and broader temperature ranges. This places much more stringent requirements on the measurement and control of the properties of the optical materials within these systems. In response to these demands, SCHOTT North America recently announced domestic production of the IG glass series (IG2-IG6) of chalcogenide glasses within the US which has spurred renewed focus the characterization to bring these glasses to a similar level as standard optical glasses. This paper will present and discuss the novel inspection systems and the process used to qualify refractive index of these materials, with a focus on data presentation, in order to demonstrate the methodology and utility of the methods and data produced.
