PURPOSE:To make halide glass permeable to infrared light rays having wavelength up to the maximum 15mum, by using halide glass comprising one or more compounds of one or more halogenous elements of Cl, Br, and I, and K, Rb, Sr, Cd, Ba, and Pb in a desired ratio. CONSTITUTION:Halide glass for infrared light transmission comprising 0-24 mol% KX [X is one or more halogenous elements of Cl, Br, and I], 0-24mol% RbX, 2-30mol% SrX2; 34-53mol% CdX2, 8-40mol% BaX2, and 0-23mol% RbX2. SrX2+BaX2 is 11-42mol%, KX+RbX is 8-26mol%, KX+RbX+SrX2+ CdX2+BaX2+PbX2 is 90-100mol%, and (Cl)/(X) [(Cl) is number of Cl element in glass, and (X) is number of halogen elements in glass ] is controlled to 0.86- 1. |
