Description
Известно стекло Дл светофильтров, включающее SiO2, MgO, ZnO, CuO, CoO.Glass is known for light filters including SiO2, MgO, ZnO, CuO, CoO.
Предлагаемое стекло отличаетс от известного тем, что оно содержит указанные компоненты в следующих количествах, вес. %: SiO2 75-80, MgO 4-8, ZnO до 10, CuO 1- 2,5, CoO 0,15-0,4 и, кроме того, К2О 4-10, Li2O 2-10, BaO до 10, Сг2Оз 0,05-0,15.The proposed glass differs from the known one in that it contains these components in the following amounts, wt. %: SiO2 75-80, MgO 4-8, ZnO up to 10, CuO 1- 2.5, CoO 0.15-0.4 and, moreover, K2O 4-10, Li2O 2-10, BaO up to 10, Cr2Oz 0.05-0.15.
Окислы ВаО, ZnO и Сг2Оз способствуют получению стекла с широкой областью пропускани в синей части спектра, а Li2O позвол ет повысить термостойкость стекол.Oxides of BaO, ZnO, and Cr2Oz contribute to the formation of glass with a wide transmission region in the blue part of the spectrum, and Li2O makes it possible to increase the heat resistance of glasses.
Ниже изобретение по сн етс конкретными примерами.The invention is illustrated below by specific examples.
Крас щие окислы СоО, CuO и СггОз вход т в состав стекла сверх 100 вес. %.Coloring oxides CoO, CuO, and Cr2O3 are part of glass in excess of 100 wt. %
Светофильтры размером 25 мм и толщиной 1,4-1,6 мм, изготовленные из предлагаемого стекла, выдерживают перепад температур 130-150° С.Light filters with a size of 25 mm and a thickness of 1.4-1.6 mm, made from the proposed glass, withstand a temperature difference of 130-150 ° C.
