Description
Изобретение относ итс к сое тавам стекла и может быть использовано при изготовлении различного рода светофильтров. Известно стекло, включающее ЗЮа, , ЕиаОт Цель изобретени - ооеспечение полной непрозрачности в ультрафиолетовой области спектра в диапазоне волн 160-200 нмв Достигаетс это тем, что стекло содержит указанные компо ненты в след2 ющем количестве,вес. Si02 99.1 - 99,7 AlaOa 0,01 - 0,5 EugO, 0,01 - 0,03 и,кроме тогр, Ti02 0,01 - 0,1 npijMipj. Высококремнеземистое стекло следующего состава, вес.1 §i02 99,i 0,05 ЕигОз TiOa Технологи изготовлени стекла обычна Предложенное стекло обеспе чйвает полную непрозрачность в дальней УФ области спектра при минимальных концентраци х добавок, что позвол ет получить высокую однородность стекла, улучшить эксплуатационные свойства (кристаллизационную стойкость м термостойкость). Введение добавки TiOg позвол ет полностью обеспечить непро зрачность стекла в дальней ультрафиолетовой области (в диапазоне менее Л 200 нм) спектра (см. чертеж).The invention relates to compounds of glass and can be used in the manufacture of various kinds of filters. Known glass, including ZUa, EiaOt The purpose of the invention is to ensure complete opacity in the ultraviolet region of the spectrum in the 160-200 nm wavelength range. This is achieved by the fact that the glass contains the specified components in the following amount, weight. Si02 99.1 - 99.7 AlaOa 0.01 - 0.5 EugO, 0.01 - 0.03 and, apart from togr, Ti02 0.01 - 0.1 npijMipj. High-silica glass of the following composition, weight.1 §i02 99, i 0.05 UgO3 TiOa (crystallization resistance and heat resistance). The addition of TiOg allows the glass to be completely opaque in the far ultraviolet region (in the range of less than L 200 nm) of the spectrum (see drawing).
