Abstract
PURPOSE: Optical glass having high refractive index and low dispersion, comprising B2O3, La2O3, Yb2O3, and F as basic components and not containing Th and Cd.
CONSTITUTION: Optical fibers comprising 20W37wt% B2O3, 34W60wt% La2O3, 1W32wt% Yb2O3, 0.1W7wt% F, 0W3wt% SiO2, 0W6wt% R2O(R2O is one or more of Li2O, Na2O and K2O), 0W18wt% RO, 0W23wt% Y2O3, 0W11wt% ZrO2, 0W12wt%, Ta2O5, 0W5wt% Nb2O5, 0W6wt% PbO, 0W10wt% WO3, 0W4wt% Al2O3, 0W5wt% TiO2, 0W16wt% GeO2, and 0W12wt% Gd3O3 (the above-mentioned F is the amount of replaced oxygen when glass is calculated as 100%). The optical glass can be obtained by using oxides, carbonates, nitrates, fluorides, etc. as raw materials for the individual components, feeding them to a platinum crucible heated at 1,200W1,400°C in an electric furnace, melting, clarifying, stirring, making them uniform, and casting them into a mold of pig iron.
