PURPOSE:To obtain halide glass capable of transmitting infrared rays of long wavelength region by composing the glass of Zr ion, Pb ion, Tl ion, and La ion of specified mol% as cationic components and F ion and Cl ion as anionic components. CONSTITUTION:The glass is composed of, by mol%, 45-63 Zr ion, 14-31 Pb ion, 0-27 Tl ion, and 0-12 La ion as cationic components with the proviso that Tl ion + La ion is 8-30, and the sum of the cationic components is >85; while the anionic components are composed of 95-100 F ion and 0-5 Cl ion. |
