Referring to FIG. 1, a method for manufacturing a pair of glasses for radar wave and ultraviolet ray comprises
S01: selecting a neodymium-iron-boron magnet as a base material, and carrying out polarization treatment on the neodymium-iron-boron magnet:

In step S01, a neodymium iron boron (Nd FeB) magnet with high light resistance is selected as a base material, so that the material is ensured to have high light resistance in the near infrared light wavelength range.
Polarization treatment of neodymium iron boron (Nd FeB) magnets using a suitable method can be achieved by applying a magnetic field or magnetizing treatment during the material preparation process, which will give the material a higher light resistance in a specific direction. The polarization surface of the NdFeB magnet is perpendicular to the light-receiving direction of the glasses, so that the polarization filter layer can filter radar waves and ultraviolet rays to the greatest extent, and the polarization filter layer has a good protection effect on eyes.
In step S02, the neodymium iron boron (Nd FeB) magnet is processed into a proper lens shape and size according to the design requirement, for example, the lens shape can be changed arbitrarily according to the design, and the neodymium iron boron (Nd FeB) magnet can be processed into an eyeglass lens through cutting, grinding, polishing and other processes.
Neodymium iron boron (Nd FeB) magnets processed into lenses need to be subjected to surface treatment, and the surfaces are smooth and flat through sanding and polishing, so that the optical performance and the comfort are improved. The neodymium-iron-boron (Nd FeB) magnet is processed to be made into a rubidium-iron-boron basic crystal.
And S03, performing film coating treatment on the surface of the rubidium-iron-boron basic crystal, wherein the film coating treatment is performed on the surface of the rubidium-iron-boron basic crystal, and the polarization performance of the film coating has an ultraviolet-proof function, so that the polarization surface of the film coating is required to be perpendicular to the light-receiving direction of the glasses.
The process of covering the rubidium-iron-boron basic crystal with the lithium titanate coating comprises the following steps:
Before the process of covering the rubidium-iron-boron basic crystal with the lithium titanate coating, a clean rubidium-iron-boron basic crystal material needs to be prepared, and the surface of the rubidium-iron-boron basic crystal is ensured to be free of dirt and impurities;
A lithium titanate solution or powder is prepared for the preparation of a lithium titanate coating.
S031: surface cleaning and surface treatment are carried out on the NdFeB basic crystal;
Before coating, the neodymium-iron-boron basic crystal is required to be subjected to surface treatment, wherein the surface treatment comprises, but is not limited to, oxide removal, polishing, cleaning and the like, so that the surface of the neodymium-iron-boron basic crystal is ensured to be clean, and the adhesion performance between the coating and the surface of the neodymium-iron-boron basic crystal is good, so that the coating can be firmly attached to the surface of the neodymium-iron-boron basic crystal.
S032: the neodymium iron stretched base crystal is covered with a lithium titanate coating;
there are two methods for covering the surface of the neodymium iron boron basic crystal with a lithium titanate coating:
The method comprises the following steps: preparing a coating by a solution method: preparing lithium titanate solution, selecting a solvent with proper lithium titanate content according to design requirements to dissolve lithium titanate, soaking a rubidium-iron-boron basic crystal sample in the lithium titanate solution to uniformly cover the surface of the sample, taking out the iron-boron basic crystal, airing and drying the iron-boron basic crystal, and obtaining a uniform lithium titanate coating after the coating is completely dried.
And two,: the physical vapor deposition method is adopted to prepare a coating: and depositing a lithium titanate film on the surface of the rubidium-iron-boron basic crystal by using physical vapor deposition equipment, and controlling the thickness and quality of the film by adjusting deposition parameters of the physical vapor deposition equipment, including deposition temperature, deposition rate and the like.
S033: and carrying out heat treatment after the coating preparation is finished.
And for the rubidium-iron-boron basic crystal prepared by the coating, heat treatment can be carried out on the rubidium-iron-boron basic crystal to improve the crystallinity and stability of the coating, and meanwhile, the binding force between the coating and the basic crystal is enhanced.
S034: the finished coating was characterized and tested.
After the preparation of the coating is finished, the coating can be characterized and tested by means of an optical microscope, a scanning electron microscope and the like, the quality and the performance of the coating are evaluated, and whether the lithium titanate coating on the rubidium-iron-boron basic crystal is qualified or not is checked.
Through the steps, the surface of the rubidium-iron-boron basic crystal can be successfully covered with the lithium titanate coating, so that the improvement of material performance and the enhancement of functions are realized.
In step S04, after the surface of the basic crystal of rubidium-iron-boron (RbFeB) is covered with a lithium titanate (LiTiO 3) coating, ion implantation treatment is also required to change the optical properties of the lithium titanate surface, so as to realize the polarization performance, thereby being applied to optical devices. The method can realize microscopic regulation and control on the surface of the material and improve the performance and the function of the material.
The ion implantation treatment of the lithium titanate surface comprises the following steps:
S041: determining an ion source and ion beam equipment, and determining ion species and energy;
the ion source and ion beam apparatus need to be prepared prior to ion implantation, and the appropriate ion species and energies are selected. Parameters of ion implantation are determined, including the ion species implanted, the implantation energy, the implantation dose, etc.
S042: cleaning the surface of lithium titanate;
before ion implantation, the surface of lithium titanate needs to be cleaned, and impurities and oxides on the surface are removed, so that the surface is ensured to be clean, and the ion implantation effect is improved.
S043: implanting ions onto the surface of lithium titanate;
The prepared ion beam is bombarded vertically on the lithium titanate surface, so that ions penetrate the surface and cause the surface to form doped regions. During ion implantation, ions interact with atoms of the material at the surface or inside, changing the chemical and structural properties of the material.
S044: annealing the NdFeB crystal subjected to ion implantation;
in order to eliminate defects and stresses introduced during the injection process, heat treatment is generally performed on the neodymium iron boron crystal, and annealing treatment is performed to improve the stability and performance of the material.
S045: characterization analysis was performed on the lithium titanate sample with ion implantation completed.
Characterization analysis, including optical properties, structural properties, etc., was performed on the ion implantation treated lithium titanate sample to verify whether ion implantation successfully altered the properties of the material.
The ion implantation treatment can change the optical property of the lithium titanate surface of lithium, realize the polarization performance, and be applied to optical devices. The method can realize microscopic regulation and control on the surface of the material and improve the performance and the function of the material.
Ion implantation related parameters: in the process of bombarding a film material by ions for realizing a polarization function, the following key parameters need to be considered:
Ion species: the ion species suitable for ion bombardment of the particular material are selected, preferably argon ion, oxygen ion.
Ion energy: the ion beam energy is determined, typically between hundreds of electron volts and thousands of electron volts, and experiments, preferably experiments claiming 3000 volts, the specific energy may vary depending on the nature of the material and the processing effect requirements.
Ion current density: the current density of the ion beam, i.e., the number of ions per unit area per unit time, is controlled to be typically between a few milliamp per square centimeter and a few tens of milliamp per square centimeter, preferably 80 milliamp).
Bombardment time: the ion bombardment time is usually between a few minutes and a few tens of minutes, and the optimum result is 60 minutes through experiments, and the specific time depends on the required doping depth and the film performance requirement.
Bombardment temperature: the temperature at which the ions are bombarded is controlled to ensure that the film material is not affected by excessive heat or excessive cooling during the bombardment, preferably at room temperature, i.e. 25 degrees celsius.
By adjusting the parameters, ion bombardment of materials such as lithium titanate and the like can be realized, and a doped region is formed, so that a polarization function is realized.
In the actual process, parameters such as ion types, ion energy, ion current density, bombardment time, bombardment temperature and the like can be optimized and adjusted according to specific materials and requirements so as to obtain the optimal treatment effect.
Through the technical scheme, the eye protection lens capable of simultaneously preventing near-infrared radar waves and ultraviolet radiation can be obtained, and the eye protection lens capable of simultaneously preventing the near-infrared radar waves and the ultraviolet radiation can be obtained by installing the lens in the lens frame.
The lens manufactured by the technical proposal is subjected to irradiation experiments,
Experimental data are as follows:
The method comprises the steps of respectively adopting an infrared radar wave with the wavelength of 900 nanometers, an ultraviolet radar wave with the wavelength of 280 nanometers, white light and three parallel beams with the power of 100 milliwatts, making the parallel beams enter a polarization filter with the thickness of 2 millimeters, and then measuring the beams penetrating through a lens by using a spectrum measuring instrument.
The result of the light beam penetrating through the light spectrum measuring instrument is respectively: the infrared light is 6.3 mW, the ultraviolet light is 8.8 mW, and the white light is 98.5 mW;
the penetration rates were obtained as follows:
900 nm infrared radar wave=6.3/100=0.063, attenuation 12DB.
280 Nm ultraviolet radar wave=8.8/100=0.088, attenuation 10.55DB.
White light = 98.5/100 = 0.985, attenuation 0.066DB.
The experiment shows that the normal white light with 100 milliwatts still has 98.5 milliwatts after penetrating through the glasses, but the 900 nanometer infrared radar wave and the 280 nanometer ultraviolet radar wave are severely reduced, so that the natural light of the glasses passes well, and the blocking effect on the near infrared radar wave and the ultraviolet rays is obvious.
Basic principle: for a polarization material neodymium iron boron (NdFeB) magnet exhibiting Gao Guangzu nm at a center wavelength, and a lithium titanate coating (Lithium tantalate) that typically reduces to a few percent of the center wavelength photoresist for other wavelengths. The particular degree of degradation depends on factors such as the optical properties, structure and composition of the material. In general, the degree of degradation of the photoresist may be related to the degree of wavelength deviation. Typically, the photoresist drops rapidly as the wavelength deviates from the center wavelength. In a polarized material, the light resistance may decrease rapidly for light off center wavelength, and the specific drop ratio may vary depending on the material characteristics. For materials such as neodymium-iron-boron magnets, the photoresist drops by about six percent of the center wavelength. It should be noted that the specific photoresist drop ratio may vary depending on the characteristics of the actual material and factors such as the optical design. Therefore, for specific polarized materials, experiments or simulation analysis can be performed to obtain more accurate photoresist degradation.
The invention and its embodiments have been described above by way of illustration and not limitation, and the invention is illustrated in the accompanying drawings and described in the drawings in which the actual structure is not limited thereto. Therefore, if one of ordinary skill in the art is informed by this disclosure, the structural mode and the embodiments similar to the technical scheme are not creatively designed without departing from the gist of the present invention.
