Description
Изобретение относитс к оптическому стеклу С высоким по.казателем преломлени при высоком коэффициенте диаперсии.This invention relates to an optical glass with a high refractive index at a high diapersion coefficient.
Известно оптическое стекло, включающее PsOs, В2Оз, ВаО, АЬОз.Optical glass is known, including PsOs, B2O3, BaO, AlO3.
Олисываемое стекло имеет 1меньшую кристаллизационную способность, чем известное, (показатель преломлени 1,60-1,62 и коэффициент дисперсии 65-60.The glass to be polished has a lower crystallization capacity than the known one (the refractive index is 1.60-1.62 and the dispersion coefficient is 65-60.
Это достигаетс тем, что оно содержит указанные KOMnoHeiBTbi в следующих количествах , вес. %: PsOs 30-45; ВгОз 5-12; ВаО 30-45; А12Оз до 8 и, кроме того, Ьа2Оз до 10; СаО до 15; ZnO до 10; TiOg до 1,5; CdO до 10; AsaOs до 2; СеО2 до 2.This is achieved by the fact that it contains the indicated KOMnoHeiBTbi in the following amounts, wt. %: PsOs 30-45; VGO 5-12; BaO 30-45; A12Oz to 8 and, in addition, La2Oz to 10; Cao up to 15; ZnO up to 10; TiOg up to 1.5; CdO up to 10; AsaOs up to 2; CeO2 to 2.

Стекла неналетооиасны и могут быть использованы без защиты поверхности, устойчивы к уЛучам, (Приращение оптической плотности АД на 1 см после облучени образца толщиной 20 мм дозой 1-10 р. составл ет 0,005-0,009.Glasses are non-odorized and can be used without surface protection, resistant to cells, (The increment of the optical density of blood pressure per cm after irradiating a sample 20 mm thick with a dose of 1-10 p. Is 0.005-0.009.
Низка кристаллизационна способность позвол ет проводить варку стекла в платиновых сосудах емкостью 3-25 л. с. данным патрубком дл выпуска стекломассы.Low crystallization capacity allows glass melting in platinum vessels with a capacity of 3-25 liters. with. this pipe for the release of molten glass.
По своим оптическим свойствам они могут быть использованы в длиннофокусных системах высокого качества изобрал-сени .By their optical properties, they can be used in high-fidelity high-quality imaging systems.
