Abstract
The invention provides a core material glass used for fiber light cone, comprising the ingredients with the following weight percentages: 8-15% of SiO2, 9-15% of B2O3, 22-32% of BaO, 10-25% of La2O3, 5-15% of Nb2O5, 0-5% of Y2O3, 1-20% of PbO and 0-5% of ZnO. The glass has optical performance index according with the requirement and has relatively good processing property, thus being suitable for manufacturing the fiber light cone.
Description
Technical field
The present invention relates to a kind of multicomponent glass of fibre optic image transmission element, particularly a kind of core material glass of making fiber light cone.
Background technology
Fiber light cone be the millions of optical fibers that are less than or equal to 10 μ m by certain regularly arranged through drawing the cone image transmission apparatus that technologies such as fusion pressure form, be widely used in photoelectric instruments such as gleam image intensifier and medical X ray machine.
Optical fiber in the fiber light cone is generally formed by core material glass and the coaxial wire drawing of cladding glass.Because optical fiber passes the needs of light and the application of domestic light cone, it requires the light cone core material glass that higher specific refractory power and higher thermal expansivity and favorable manufacturability energy must be arranged, and obtains numerical aperture preferably and good devitrification resistance energy and good resistance to cleavage so that cooperate with cladding.Because performance is special, does not have commercial light cone core material to supply on the market.CN1229292C has announced a kind of light cone glass of fiber core component, and its glass refraction and the coefficient of expansion are lower, and the manufacturing cost that costs an arm and a leg is higher, can not satisfy the production domesticization needs.
Summary of the invention
The purpose of this invention is to provide a kind of high refractive index, high expansion coefficient, the good fiber light cone core material glass of processing performance.
The technical scheme of technical solution problem of the present invention is: a kind of core material glass that is used for fiber light cone, its components in weight percent comprises: SiO
2: 8～30%; B
2O
3: 5～20%; BaO:15～40%; La
2O
3: 10～25%; Nb
2O
5: 5～15%; Y
2O
3: 0～5%; PbO:1～20%; ZnO:0～8%.
The invention has the beneficial effects as follows: by adjusting the content size of invention component and each component, obtained the light cone core material glass of high refractive index high expansion coefficient, the optical property index meets the requirements, and processing performance is better, and manufacturing cost is lower,
Embodiment
B
2O
3, SiO
2Be that glass generates body, B
2O
3Generating body as glass is the important composition of making high-refractivity and low-dispersion glass, considers that simultaneously the manufacturing process of light cone needs higher chemical stability and physical strength.By experiment, SiO
2Weight percent content is 8～30%, B
2O
3Weight percent content is 5～20%, and is proper.
BaO, La
2O
3Be the desirable component of high-refraction low-dispersion optical glass for mold, the present invention uses as major ingredient.By experiment, the weight percent of BaO is 15～40%, La
2O
3Weight percent content 10～25% relatively suitably.
Nb
2O
5, Y
2O
3All can improve the processing performance of glass.Experiment showed, Nb
2O
3Weight percent content 5～15%, Y
2O
3Weight percent content proper 0～5%.
Pb-O key among the PbO has covalant character, enters network with low coordination easily, promotes the glass forming process, has good fluxing action, and can improve the every performance of glass.By experiment, the weight percent content of PbO 1～20% relatively rationally.
TiO
2Introducing, make opticglass increase network oxide content, thereby reduce specific gravity of glass and high temperature viscosity, the elimination of glass metal clarification and striped in the helping material process.Its weight percent content is proper 1～10%.
Following table is the every index contrast to four embodiment of the present invention, and the numerical value of each component is weight percent values in the table.
As seen from the above table, suitably proportioning is respectively formed in adjustment, and each performance index of product are suitable for making fiber light cone.
