Specific embodiment
All features disclosed in this specification can be with any other than mutually exclusive feature and/or step
Mode combines.
I. optical glass
Optical glass of the invention considers to contain without expensive component on the basis of existing green and environment-friendly glass
Amount, obtaining refractive index (nd) is 1.60-1.70, and Abbe number (vd) is 40-55, and stress optical coefficient (B) is 2.5 × 10-12/Pa
((- 40-80 DEG C) of (dn/dt) is 4.0 × 10 hereinafter, thermal refractive index coefficient-6/ DEG C the excellent optical glass of chemical stability.
The composition of optical glass of the invention is described in detail below, the content of each glass ingredient, total content do not have such as
There is special instruction, is then all indicated using weight percent.In addition, in the following description, mentioning specified value or less or rule
It also include the specified value when more than definite value.
[necessary component and optional Component]
SiO2It is that glass generates body, is to form the necessary oxide components of glass.In the present invention system if SiO2's
Content is lower than 20%, operates although being conducive to glass melting process, and the chemistry of obtained glass is durable low；But if SiO2's
Content is higher than 44%, although being conducive to improve chemical durability, increases glass melting difficulty.Therefore, SiO2Content be
20~44%, preferably 25~40%.
Suitable B is added in the present invention2O3And a kind of optical glass network generates oxide body, can increase stabilization
Property, and it is very useful to glass melting performance, preferably its content is 6% or more.But work as B2O3Content, can be right at 15% or more

The humidity of the optical glass of acquisition is deteriorated, and increases technology difficulty and cost burden；RO content is too low, the transmission of optical glass
Rate, Abbe number and degree of staining λ80/λ5It is all difficult to reach perfect condition.RO of the present invention is preferably BaO and/or CaO.
Wherein, CaO is necessary component of the invention, by introducing the CaO of proper content, can improve the chemical stabilization of glass
Property, the water-resistant stability of glass is improved, and reduce the density of glass；But when its content is more than 10%, the chemical stabilization of glass
Property deteriorate instead, and optical transmittance decline, therefore the content of CaO be 0-10%, preferably 1-6%.BaO is to improve optics glass
The optical constant of glass, reduces the crystallization temperature of glass, improves the ingredient of glass devitrification resistance, be in optical glass of the present invention must
It hanks point.By the way that 40% or more BaO is added, one can effectively improve optical glass refractive index, glossiness；Secondly improving optics
Transmitance, Abbe number and the degree of staining λ of glass80/λ5, stress optical coefficient and thermal refractive index coefficient, if its content is more than
55%, then glass chemistry stability is deteriorated, and crystallization property can also be deteriorated.Therefore the content of BaO is 40-55% in the present invention, preferably
Content is 45-50%.
It is a small amount of to introduce Al2O3The chemical stability of glass can be effectively improved, it, can be effective when especially its content is more than 0.5%
Improve the stability of glass；But when its content is more than 9%, the meltbility of optical glass is deteriorated, and devitrification resistance reduces, therefore this hair
Bright Al2O3Content be 0-9%, preferably greater than 0-3%.
By adding Sb on a small quantity2O3Component, it is very useful for eliminating glass blister, but work as Sb2O3When content is more than 3%,
It will affect the transmitance of glass, therefore Sb of the present invention2O3Additive amount be 0-3%, it is excellent to select 0-1%.
The present inventor has found by lot of experiments, passes through control (ZnO+RO)/B2O3Range be 3.06-11.5, can
Obviously to lower the stress optical coefficient and thermal refractive index coefficient of glass, and guarantee that glass has preferable transmitance, preferably
For 3.34-10.3, more preferably 4-8；Pass through control (SiO2+RO)/(ZnO+B2O3+TiO2) range be 1.97-14.86, it is excellent
2.81~8.63 are selected as, the stability of glass network structure can be significantly improved, further increases glass moisture-resistance, is guaranteed
Glass has compared with low stress optical coefficient and thermal refractive index coefficient.
[component that should not contain]
In the range of not damaging glass performance of the invention, can add as needed other above-mentioned not referred at
Point.But the transiting metal components such as V, Cr, Mn, Fe, Co, Ni, Cu, W and Mo, even if the feelings contained on a small quantity independent or compoundly
Under condition, glass is also subject to coloration, and the specific wavelength in visible light region generates absorption, so that it is visible to weaken raising of the invention
The property of light transmission rate effect, therefore it is desirable, especially for the optical glass that the transmitance of visible light region wavelength requires, preferably
Do not include actually.P2O5It is complicated to be easy the moisture absorption, blending process, photosensitiveness is difficult to control, therefore is not preferably contained in the present invention
P2O5。
Li2O、K2O or Na2The alkaline metal oxide of O, the network knot that can have corrosion function to smelting apparatus, destroy glass
Structure simultaneously makes its crystallization property be deteriorated, therefore Li is not preferably contained in the present invention2O、K2O or Na2O。
