Изобретение относитс к составам оптических стекол с особым ходом дисиерсин, используемым дл изготовлени линз, призм и других деталей.The invention relates to optical glass compositions with a particular course of dissersin used to make lenses, prisms and other parts.
Известно оптическое стекло, включающее ВзОз, AlaOs, ZazOs, PbO, CaO, АзгОз.Optical glass is known, including VOSO, AlaOs, ZazOs, PbO, CaO, AzgOz.
Цель изобретени - снизить относительную частную дисперсию.The purpose of the invention is to reduce the relative partial dispersion.
Достигаетс это тем, что стекло содержит указанные компоненты в следующем количестве , вес. %:This is achieved by the fact that the glass contains these components in the following quantity, weight. %:
ВаОз основа; AlgOs 6-15; ZaaOa 8-15; PbO 15-25; CaO 1-5; АзгОз 0,3-0,5.VOOz basis; AlgOs 6-15; ZaaOa 8-15; PbO 15-25; CaO 1-5; AzgOz 0.3-0.5.
Кроме того, стекло может дополнительно содержать ло крайней мере один компонент из группы: Vt203, CdO, SrO, BaO 1-5 вес. %, a также по крайней мере один компонент из группы NbjOs, Ta20s 1 - 10 вес. % и ZrO2 0,5-5,0 вес. %, Са2Оз 5-10 вес. % и Ge02 вес. %.In addition, glass may additionally contain at least one component from the group: Vt203, CdO, SrO, BaO 1-5 weight. %, a also at least one component from the group NbjOs, Ta20s 1 - 10 weight. % and ZrO2 0.5 to 5.0 weight. %, Ca2Oz 5-10 weight. % and Ge02 weight. %
В таблице приведены составы стекол и их свойства.The table shows the compositions of glasses and their properties.
