Description

Изобретение относится к составам оптического стекла, используемого в приборостроении.The invention relates to compositions of optical glass used in instrumentation.

Известно оптическое стекло, содержащее, мас.%: SiO2 2,7-5,5; BaO 41,6-46,4; TiO2 22,4-25,2; B2O3 5,6-6,7; Al2O3 10,4-11,7; PbO 7,1-14,2; K2O 0,1-0,2; Na2O 0,05-0,1 [1].Known optical glass containing, wt.%: SiO 2 2,7-5,5; BaO 41.6-46.4; TiO 2 22.4-25.2; B 2 O 3 5.6-6.7; Al 2 O 3 10.4-11.7; PbO 7.1-14.2; K 2 O 0.1-0.2; Na 2 O 0.05-0.1 [1].

Цель изобретения - повышение показателя преломления стекла.The purpose of the invention is to increase the refractive index of glass.

Цел достигается тем, что в состав стекла дополнительно вводят Sb2O3 и ZnO, при следующем соотношении компонентов, мас.%: SiO2 4,0-7,0; BaO 35,0-40,0; TiO2 20,0-25,0; B2O3 5,0-7,0; PbO 14,0-16,0; K2O 4,5-6,0; Sb2O3 0,5-1,0; ZnO 5,0-10,0.The goal is achieved by the fact that Sb 2 O 3 and ZnO are additionally introduced into the glass composition, in the following ratio of components, wt.%: SiO 2 4.0-7.0; BaO 35.0-40.0; TiO 2 20.0-25.0; B 2 O 3 5.0-7.0; PbO 14.0-16.0; K 2 O 4,5-6,0; Sb 2 O 3 0.5-1.0; ZnO 5.0-10.0.

В таблице приведены составы стекла.The table shows the compositions of glass.
