Abstract

Amorphous Materials serves as a source of high purity IR transmitting chalcogenide glasses. Based primarily on the element selenium, the glasses are used for optical elements in passive IR optical systems. However, because of their transparency in the IR combined with chemical inertness, the glasses can be used to fabricate ATR plates for chemical analysis. Addition of the element tellurium extends the long wavelength transparency of selenium glasses increasing their suitability for use as IR fiber materials. Uncoated fibers may be used in the same manner as ATR plates for chemical analysis. Production of glass and fibers are discussed.
