2o
3, the BaO of the 2% and TiO2 of 2%, described green colourant comprises following composition: the K2Cr2O7 of FeO, 40-60 weight part of 40-60 weight part, in described composition, the weight percentage of parent glass composition is 99.5%, and the weight percentage of green colourant is 0.5%.The present invention is by Reasonable adjustment green optical glass combination composition formula, and improve the chemical stability of glass, uniform coloring, crystallization ability is good, and specific refractory power is high.
Description
Technical field
The present invention relates to a kind of green optical glass composition, belong to optical element field.
Background technology
Color optical glass also known as optical lightscreening glass, it be mainly used to make observe, take a picture, the spectral filter of the instrument such as infrared, improve instrument visibility meter to reach or meet some particular requirement, also can make tinted glasses.The effect of color optical glass is: the light through specific wavelength that it can be selected; Singlet line can be isolated from discontinuous spectrum; Or by leaching the spectral range of one fixed width in continuous print spectrum or evenly weakening the spectrum etc. of white light.
Existing green optical glass composition, painted even not, crystallization ability, can not meet the demand of user.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art part, a kind of green optical glass composition is provided.
Green optical glass composition of the present invention, is made up of parent glass composition and green colourant, and described parent glass comprises following composition according to weight percentage: the SiO2 of 81%, the Al of 2%
2o
3, the CaO of 4%, the MgO of 4%, the B of 5%
2o
3, the BaO of the 2% and TiO2 of 2%, described green colourant comprises following composition: the K2Cr2O7 of FeO, 40-60 weight part of 40-60 weight part, in described composition, the weight percentage of parent glass composition is 99.5%, and the weight percentage of green colourant is 0.5%.
Preferably,
Described green colourant comprises following composition: the FeO of 50 weight parts, the K2Cr2O7 of 50 weight parts.
The present invention is by Reasonable adjustment glass formula, and improve the chemical stability of glass, uniform coloring, crystallization ability is good, and specific refractory power is high.
