Abstract
The invention provides a purple optical glass composition, comprising a base glass ingredient and a purple coloring agent, wherein the base glass comprises the following components by weight percent: 81% of SiO2, 2% of Al2O3, 4% of CaO, 4g of MgO, 5% of B2O3, 2% of BaO and 2% of TiO2; the purple coloring agent comprises the following components in parts by weight: 40-50 parts of MnO2, 20-30 parts of CoO and 20-30 parts of Co2O3; the weight percent of the base glass ingredient in the composition is 99.5% and the weight percent of the purple coloring agent is 0.5%. By reasonably adjusting the formula of the purple optical glass composition, the chemical stability of the glass is improved, and the purple optical glass composition is even in coloring, good in crystallization ability and high in refractive index.
Description
Technical field
the present invention relates to a kind of Violet optical glass composition, belong to optical element field.
Background technology
Color optical glass claims again optical lightscreening glass, and the spectral filter that it is mainly used to make observation, photograph, the instrument such as infrared, improves instrument visibility meter or meet some particular requirement to reach, and also can make tinted glasses.The effect of color optical glass is: the light that sees through specific wavelength that it can be selected; Can from discontinuous spectrum, isolate singlet line; Or by leaching the spectral range of certain width in continuous spectrum or evenly weakening spectrum of white light etc.
Existing Violet optical glass composition, painted even not, crystallization ability, can not meet user's demand.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art part, a kind of Violet optical glass composition is provided.
Violet optical glass composition of the present invention, is made up of parent glass composition and violet colorant, and described parent glass comprises following composition according to weight percentage: 81% SiO2,2% Al
2o
3, 4% CaO, 4% MgO, 5% B
2o
3, 2% BaO and 2% TiO2, described violet colorant comprises following composition: the Co2O3 of the MnO2 of 40-50 weight part, the CoO of 20-30 weight part and 20-30 weight part, in described composition, the weight percentage of parent glass composition is 99.5%, and the weight percentage of violet colorant is 0.5%.
Preferably,
Described violet colorant comprises following composition: the Co2O3 of the MnO2 of 45 weight parts, the CoO of 25 weight parts and 25 weight parts.
The present invention, by rationally adjusting glass formula, has improved the chemical stability of glass, uniform coloring, and crystallization ability is good, and specific refractory power is high.
