Abstract

A new family of fluoride glasses mainly based on InF3 and BaF2 has been optimized in order to increase the resistance against devitrification. These rrulticomponent glasses showing an exceptional transmission from 0.2 μ to 8 μm are potential candidates for the 3-5 μm region either in bulk or fibers. A second new group of I.R. glasses has been discovered in the Te-CI and Te-Br binary systems. These glasses exhibit a large transparency domain lying from 2-13 μm for the Te3Cl2 glass and 2-18 μm for the Te3Br2 glass. This original class of vitreous material shows a good resistance against devitrification, reasonable stability in normal atmosphere and glass temperatures in the 80-90°C range.
