Paper Abstract

Recently there has been a growing interest in using fluoride glass rather than crystalline materials for mid-infrared bulk optics. Applications in infrared bulk materials include high-power and low-power laser optics which involve windows, domes and lenses and infrared spectrophotometry which also requires windows as well as fluoride glass light pipes or conduits. Two types of fluoride glass, namely ZrF4- based and A1F3-based glass, are generally used for mid-infrared bulk optics. Although both glasses exhibit high optical transparency in the wavelength region from 0.3 microns to 7.0 microns, zirconium fluoride glass differs to a greater extent from aluminum fluoride glass in terms of its chemical durability, mechanical strength and glass forming ability. Thus, in selecting the type of fluoride glass, each criterion should be carefully weighed for each bulk optics application.
