Description

(Изобретение относитс  к составам оптических фторфосфорных стекол, используемых дл  создани  оптических систем. Известно оптическое стекло, содержащее А1Рз, Сар2, SrFa, MgO. . Дл  повышени  коэффициента дисперсии и показател  преломлени  и снижени  кристаллизационной способности, предлагаемое стекло дополнительно содержит Ва(РОз)2 и Вар2 при следующем соотношении компонентов, мол. %: 4,5-15 MgO 10-15 Ва(РОз)2 , В таблице приведены конкретные составы редложенного стекла (в мол. %) и соответтвующие им физико-химические свойства (The invention relates to compositions of optical fluorophosphoric glasses used to create optical systems. Optical glass containing A1Pz, Cap2, SrFa, MgO is known. To increase the dispersion coefficient and the refractive index and reduce the crystallization ability, the proposed glass additionally contains Ba (Rho2) 2 and Var2 in the following ratio of components, mol.%: 4.5-15 MgO 10-15 VA (PO3) 2. The table shows the specific compositions of the glass laid (in mol.%) and the physicochemical properties corresponding to them.

Дл  снижени  летучести и обеспечени  устойчивости к кристаллизации вводитс  окись магни  в количестве 4,5-5 мол. %. Технологи  приготовлени  стекла обычна .To reduce volatility and provide resistance to crystallization, magnesium oxide is introduced in the amount of 4.5-5 mol. % Glass making techniques are common.

Предлагаемые оптические стекла по оптическим посто нным в диаграмме Аббе (по - VD) располагаютс  вне области известных стекол. По водоустойчивости стекла эти стекла относ тс  к первому гидролитическому классу, по п тнаемости - к третьей группе и по налетоопасности - к классу а. Стекла не кристаллизуютс  из расплава при 3-час выдержке в опасной зоне дл  кристаллизации.Optical glasses according to optical constants in the Abbe diagram (in terms of - VD) are located outside the region of known glasses. According to the water resistance of glass, these glasses belong to the first hydrolytic class, according to puncture - to the third group and according to flying hazard - to class a. The glasses do not crystallize from the melt at 3-hour exposure in the hazardous crystallization zone.

Стекла прозрачны в интервале длин волн 245-4000 нм при толщине образцов 10 мм. 3 Предмет изобретени  Оптическое стекло, содержащее А1Рз, CaFs, SrFs и MgO, отличающеес  тем, что, с целью повышени  коэффициента дисперсии, 5 показател  преломлени  и снижени  кристаллизационной способности, оно дополнительно 4 содержит Ва(РОз)2и ВаРг при следующем соотношении компонентов (мол. %): AlFs38-40 CaF214-20 5гр219-30 MgO4,5-5 Ва(РОз)210-15 BaF24,5-5.The glasses are transparent in the wavelength range of 245–4000 nm with a sample thickness of 10 mm. 3 Object of the invention Optical glass containing A1P3, CaFs, SrFs and MgO, characterized in that, in order to increase the dispersion coefficient, 5 refractive index and decrease the crystallization capacity, it additionally contains 4 Ba (PO3) 2 and BaRg in the following ratio of components (mol .%): AlFs38-40 CaF214-20 5gr219-30 MgO4.5-5 Ba (PO3) 210-15 BaF24.5-5.
