Description

Изобретение относитс  к сос оптического стекла, используем дл  изготовлени  линз. Известно оптическое стекло, чающее, вес.%: Наиболее близким к изобрете со  вл етс  оптическое стекло, щее,вес.%: 18 - 23 $iO 7,6-14,8 27 , 1-46,2 3,6-19,2 0,8-16, 1 1 - 3,5 0-6 до О, 1 0,1 О -18 СаО, .гО, Mg-O, ZnO до 2 2.У таких стекол уменьшенное пропускание в видимой части стектра. Кроме того, вследствие наличи  в известных стеклах ZrO2 более высока  температура варки. Цель изобретени  - обеспечение показател  преломлени  160-1,72, коэффициента дисперсии 44-62. Цель достигаетс  тем, что стекло имеет состав, вес.%: Si022-19 В, О,14-48 в1с/. 35-56 сао1 - 20 Дл  улучшени  технологических свойств стекло дополнительно может содержать , по крайней мере, один окисел из р да: , , СаО, , 2n(j, РЬ С, вес.%; причем: 0,1 - 13 0,1 - 10 0,1 - 18 0,1 - 20 0,1 - 35 0,1 - 8 0,1 - 20 0,1 - 45 Кроме того + N,ajO 4 СаО MgO + ;.i(j 1- ЛС„о, 1 La,,O, составл етThe invention relates to an optical glass core, used for the manufacture of lenses. Optical glass is well known; weight% is: The closest to the invention is optical glass, weight%: 18 - 23 $ iO 7.6-14.8 27, 1-46.2 3.6-19 , 2 0.8-16, 1 1 - 3.5 0-6 to O, 1 0.1 O-18 CaO, .gO, Mg-O, ZnO to 2 2. Such glasses have reduced transmittance in the visible part of the spectrum . In addition, due to the presence of ZrO2 in known glasses, the cooking temperature is higher. The purpose of the invention is to provide a refractive index of 160-1.72, a dispersion coefficient of 44-62. The goal is achieved by the fact that glass has a composition, wt.%: Si022-19 B, O, 14-48 v1c /. 35-56 cao1 - 20 To improve the technological properties of the glass, it may additionally contain at least one oxide from the series:,, CaO,, 2n (j, Pb C, wt.%; And: 0.1 - 13 0, 1 - 10 0.1 - 18 0.1 - 20 0.1 - 35 0.1 - 8 0.1 - 20 0.1 - 45 In addition + N, ajO 4 CaO MgO +; .i (j 1- BOS, 1 La ,, O, is

В св зи с большим содержанием ВаО, 2dO, в стекле обеспечиваютс  высокие числа Лббе.Due to the high BaO 2dO content in the glass, high Lbbe numbers are provided.

Стекла имеют показатель преломлени  1,60 - 1,72 при числах Лббе Ve - 34-62.Glasses have a refractive index of 1.60 - 1.72 for Lbbe Ve numbers of 34-62.
