Description

Изобретение относитс  к оптическим стеклам и может быть применено в светосильных оптических системах.The invention relates to optical glasses and can be applied in high-aperture optical systems.

Известно оптическое стекло, включающее GeOa, ЬазОз, ZrOzОписываемое стекло имеет более высокий показатель преломлени .Optical glass including GeOa, LazOz, ZrOz is known. The described glass has a higher refractive index.

Это достигаетс  тем, что опо содержит указанные компоненты в следующих количествах , мол. %: GeO2 40-80, Ьа2Оз 15-23, ZrOa 3-15, и кроме того, HfO2 1-10.This is achieved by the fact that the opo contains these components in the following amounts, mol. %: GeO2 40-80, La2Oz 15-23, ZrOa 3-15, and in addition, HfO2 1-10.

Также с целью снижени  кристаллизационной способности оно дополнительно содержит до 20 мол. % АЬОз, ВаО, ВгОз, CdO, СаО, SiOz, NbaOg, SiO, TiOg, ZnO, LaFs, BaFg, SrF2, CaF2 и до 2 мол % CeO2.Also, in order to reduce the crystallization ability, it additionally contains up to 20 mol. % ABO3, BaO, BrO3, CdO, CaO, SiOz, NbaOg, SiO, TiOg, ZnO, LaFs, BaFg, SrF2, CaF2 and up to 2 mol% CeO2.

Введение двуокиси гафни  в количестве до 10 мол % позвол ет улучщить оптические константы и расщирить их пределы. Описываемое оптическое стекло имеет показатель преломлени  пв 1,8-1,93 и коэффициент дисперсии V 35-45.The introduction of hafnium dioxide in an amount of up to 10 mol% makes it possible to improve optical constants and expand their limits. The described optical glass has a refractive index of PV 1.8-1.93 and a dispersion coefficient V 35-45.
