This.
The content of the invention
In view of this, it is necessary to provide a kind of refractive index (nd) in 1.92279~1.92319, Abbe number (Vd) 20.00
Between~21.00, meltdown property is good, and refractive index is high, it is easy to the H-ZF62 optical glass of shaping.
A kind of H-ZF62 optical glass that the present invention is provided, the parts by weight of its chemical composition are：NaPO3：2.20~
2.58 parts, Ba (PO3)2：18.28~18.65 parts, BaCO3：0.75~1.25 part, TiO2：4.95~5.35 parts, Nb2O5：43.80
~45.35 parts, ZnO：0~1.00 part, Zn (NO3)2：0~3.00 part.
A kind of preparation method of H-ZF62 optical glass, it comprises the following steps：Each raw material is weighed by said ratio, fully
Added after well mixed in optical glass smelting furnace, the glass of this melting is poured into advance by fusing, clarification, stirring homogenizing, cooling
It is molded and anneals in preheated metal die, that is, obtains the optical glass.
The present invention has advantages below：
First, be free of in H-ZF62 optical glass of the invention to environmental hazard very big PbO, As2O3, CdO, and this production
The refractive index (nd) of product is that 1.92279~1.92319, Abbe number (Vd) is 20.00~21.00, possesses high index of refraction, low Abbe
Number, in special optical system design is carried out, can realize the purpose made up with correcting chromatic aberration；
Second, H-ZF62 optical glass meltdown properties of the invention are good, it is easy to be molded, and optical constant is stable, uniformity
Good, bubble, striped grade are excellent, simple production process, and yields is high；
3rd, expensive Ta is not contained in H-ZF62 optical glass of the invention2O5、Bi2O3、GeO2Composition, cost
It is relatively low, it can preferably meet the optical glass market demand.
Embodiment
With reference to specific embodiment, the present invention will be described in detail, and the description of this part is only exemplary and explained
Property, there should not be any restriction effect to protection scope of the present invention.
A kind of H-ZF62 optical glass that present embodiment is provided, the parts by weight of its chemical composition are：NaPO3：2.20
~2.58 parts, Ba (PO3)2：18.28~18.65 parts, BaCO3：0.75~1.25 part, TiO2：4.95~5.35 parts, Nb2O5：
43.80~45.35 parts, ZnO：0~1.00 part, Zn (NO3)2：0~3.00 part.
Preferably, the parts by weight of the H-ZF62 optical glass chemical composition are：NaPO3：2.29~2.31
Part, Ba (PO3)2：18.40~18.50 parts, BaCO3：0.85~1.03 part, TiO2：5.00~5.20 parts, Nb2O5：44.00~
44.50 part, ZnO：0~1.00 part, Zn (NO3)2：0~1.00 part.
BaO is optical glass network outer body in the present invention, and it can increase refractive index, density, glossiness and the chemistry of glass
Stability, BaO can effectively accelerate glass melting when content is relatively low, but content is too low, and the refractive index and Abbe number of glass can not
It is in required scope, and the meltdown property of glass is bad；But when content is excessive, clarification can be made secondary bubble, glass occur
The chemical stability of glass is deteriorated, and crystallization property can also be deteriorated.In the present invention, BaO is with Ba (PO3)2And BaCO3Two kinds of raw materials are introduced.
