Abstract

The invention relates to the technical field of optical glass materials, in particular to novel anti-radiation optical glass and a preparation method thereof.The preparation method comprises the following steps that raw materials including boric acid, lanthanum oxide, zirconium oxide, quartz sand, niobium oxide, zinc oxide and titanium oxide are mixed and then sequentially subjected to melting, clarification, homogenization and forming treatment, an optical glass substrate is prepared, and the optical glass substrate is obtained; and then performing magnetron sputtering on the surface of the substrate, controlling the rotation of the substrate in the sputtering process, and then performing coating treatment on the optical glass substrate through a coating machine to obtain the novel anti-radiation optical glass. The compact protective layer is formed on the surface of the substrate through magnetron sputtering, metal ions and the like in the optical glass substrate are prevented from migrating to the surface functional layer, the metal ions are prevented from affecting the light transmission of the surface functional layer, the impedance performance of the optical glass substrate to ultraviolet rays and near-infrared light is improved through the coating layer on the surface layer of the substrate, and the service life of the optical glass substrate is prolonged. And the finished glass substrate can stably maintain high-transmittance and anti-ultraviolet radiation performance for a long time.

Description

Technical field [0001] The present invention relates to the technical field of optical glass material, and more particularly to a new type of anti-radiation optical glass and a preparation method thereof. Background technique [0002] The optical glass can change the direction of propagation of the light, and can change the relative spectral distribution of ultraviolet, visible or infrared light. The narrow optical glass refers to the colorless optical glass; generalized optical glass also includes colored optical glass, laser glass, quartz optical glass, anti-radiation glass, ultraviolet optical glass, fiber optics, acoustic glass, magneto-optical glass and optical color glass grass. Optical glasses can be used to make lenses, prisms, mirrors, and windows in optical instruments. Components made of optical glass are key components in optical instruments. [0003] On the other hand, with the rapid development of electronic products, myopia is getting more and more tended, generali...
