Abstract

PURPOSE:To obtain optical glass having a high value of Abbe's number to the refractive index and satisfactory devitrification resistance by using B2O3-La2O3- Gd2O3-RO glass as basic glass and adding F as a substitute component for O in the glass. CONSTITUTION:This glass contains ME (metallic elements), O and F, and the ME are shown as oxides as follows: by wt., 25-48% B2O3, 20-56% La2O3, 1-37% Gd2O3, 0-15% MgO, 0-25% CaO, 0-28% SrO, 0-28% BaO, 0-17% ZnO, 0-6% SiO2, 0-6% GeO2, 0-6% ZrO, 0-3% SnO2, 0-6% Al2O3, 0-2% in total of one or more among Li2O3, Na2O and K2O, and 0-0.5% As2O3 and/or Sb2O3. In the composition the total amount of La2O3 and Gd2O3 is 28-64%, and that of one or more among MgO, CaO, SrO, BaO and ZnO is 0.5-28%. F is contained by 2-21wt% as a substitute component for part of said oxides.
