Description
Известно оптическое стекло, включающее РгОз, ВаО, LaaO.,.Optical glass is known, including PrO3, BaO, LaaO.,.
Описываемое стекло имеет показатель преломлени п° 1,55-1,65 коэффициент дисперсии v 55-68 и .химически более устойчиво .The described glass has a refractive index of n ° 1.55-1.65 and a dispersion coefficient of v 55-68 and is chemically more stable.
Это достигаетс те.м, что оно содержит указанные компоненты в следующих соотношени х , % по весу:This is achieved by the fact that it contains the indicated components in the following ratios,% by weight:
РгО,35-78PrO, 35-78
