Description

A kind of optics compound glass
Technical field
The present invention relates to optics field more particularly to a kind of optics compound glass.
Background technology
In recent years, the optical glass that refractive index (nd) is 1.60-1.70, Abbe number (vd) is 40-50 is widely used in In imaging, projection, telecommunication, optical communication engineering and laser technology application field, but at present such optical glass there are still Various problems.
Optical glass needs to have preferable chemical stability, could improve non-defective unit in the processing in later stage and plated film flow Rate.Based on such glass mostly uses borate system at present, then add a certain amount of rare earth oxide, alkali metal oxidation Object and alkaline earth oxide.As B in such glass system2O3When content is larger, chemical stability is deteriorated. B containing 30-40% in optical glass disclosed in CN101389574A2O3, chemical stability is poor, especially water resistance compared with Difference.
In recent years, the market competition of optical glass is growing more intense, only cost of material is low, product of excellent combination property Has stronger competitiveness.CN1198414A disclose with the close optical glass containing rare earth of above-mentioned optical constant range, But it contains the Nb of 31-50%2O5, cost of material is substantially increased, is unfavorable for improving the competitiveness of product.
Invention content
That the technical problem to be solved in the present invention is to provide a kind of costs is relatively low, chemical stability is good and has 1.60- 1.70 Refractive index, 40-50 Abbe number optics compound glass.
In order to solve the above technical problems, the technical scheme is that：A kind of optics compound glass, innovative point are： Its composition indicates by weight percentage, contains：SiO2：20-50%；B2O3：0- 15%；TiO2：1-15%；ZnO：2-20%； BaO：15-50%；Al2O3：0-10%；Fe3O4：0-10%；ZrO2：0-10%；Nb2O5：0-15%；La2O3：0-10%； Gd2O3：0-10%；Y2O3：0-10%；Yb2O3：0-10%；MgO：0- 10%；CaO：0-15%；SrO：0-10%；Li2O：0- 10%；Na2O：0-15%；K2O：0-15%；Sb2O3：0-1%.
Further, the content of each component meets the one or more in following 6 kinds of situations：
(1)SiO2+B2O3：25-55%；
(2)TiO2+ZnO：9-30%；
(3)BaO/TiO2：1-7 .5；
(4)(MgO+CaO+SrO+BaO)/ZnO：0 .5-9；
(5)Li2O+Na2O+K2O：2-18%；
(6)ZnO/(Li2O+Na2O+K2O)：0 .3-4.
The advantage of the invention is that：
1）：The present invention is reducing even without Nb2O5Under the premise of, by optimizing alkali metal, alkaline-earth metal, ZnO and TiO2 Content, obtain the glass that of low cost, chemical stability is good, crystallization property is excellent, optical glass has 1 .60-1 .70 the Abbe number of refractive index, 40-50 can be widely applied to imaging, projection, telecommunication, optical communication engineering and laser In technical applications, the needs of Modern New photovoltaic are disclosure satisfy that.
