Paper Abstract

The optical literature indicates that there has been much research into the fabrication and testing of infrared fiber optics (IRFO's) (1-6). Unfortunately for the spectroscopist, the majority of the research has been toward the goal of low-loss communications fiber applications. This application does not require transmission out into the fingerprint region of the mid-infrared. The chalcogenide glasses such as germanium:arsenic:selenium solutions, and heavy metal fluorides such as ZrF4 have received the most attention. There are several classes of materials which have been rejected for communications use, which would work quite well as spectroscopic or thermal energy relay systems, if the mechanical requirements are not too stringent. Some of these materials are now starting to be used in spectroscopy (7). This poster will detail progress with two types of metal halides. Specifically, we have produced fibers from silver bromide/chloride and potassium bromide/chloride. The latter is a core:clad structure. The fabrication methods employed are similar to methods described in the literature (8). These metal halide fibers are polycrystalline (pc) in structure. Of particular interest are the alkali halides (9) which can theoretically have very low scatter, due to their low refractive index and high purity.
