Abstract
The utility model belongs to the optical technical field. The utility model relates to a new eye protecting glasses which can be manufactured by making use of an optical multi-layer coating film. The utility model is composed of a glass substrate 1, an oxide 2 with high index of refraction. An oxide with low index of refraction or a halide 3, and a metal 4. The utility model can make use of the technology that the multi-layer film can be coated in vacuum way to coat the multi-layer metal medium combined film on the glass substrate so as to form a waveband gating optical filter. The utility model not only can keep down the harmful light, simultaneously but also can make the lenses have higher transparency in the visible light. The utility model is characterized in that the utility model can still more thoroughly block off the harm for the people's eyes from the ultraviolet and infrared harmful light ray. The utility model is an ideal eyes protecting tool for the workers and the field men for the steel-smelting operation, the boiler operation, and the welding operation, etc.
Description
The invention belongs to optical technical field, relate to a kind of optical multilayer coating technique that utilizes and improve novel protective eye lens.
In a lot of working environments; there are a large amount of very strong ultraviolets and the radiation of Infrared; and these harmful light be can't see by people's eyes; under such environment, work for a long time; badly will be caused very major injury if do not protect or protect to people's eyes; traditional sunglasses; what protective glasses adopted is the eyeglass that heat absorbing glass or plastics are made; harmful light is absorbed; often can not absorb efficiently ultraviolet and infra-red radiation simultaneously; and the transparency of visible light will make transparency can not satisfy job demand with the increase of the absorption of harmful light is descended rapidly.
The objective of the invention is to overcome prior art can not absorb ultraviolet and infra-red radiation simultaneously efficiently, and the transparency decline of visible light can not be satisfied problems such as job demand.A kind of novel multicoating protective eye lens is provided.
Detailed content of the present invention:
The present invention is made up of substrate of glass 1, high refractive index oxide 2, low-refraction oxide or halogenide 3, metal 4, as shown in Figure 1: the first step prepares high index of refraction at oxide 2 on substrate of glass 1, second step preparation low-refraction oxide or halogenide 3 on high refractive index oxide 2, the 3rd step is preparation metal 4 on low-refraction oxide or halogenide 3, preparation low-refraction oxide or halogenide 3 on metal 4, the 4th step repeated three steps of N order, and the 5th step is preparation high refractive index oxide 2 on low-refraction oxide or halogenide 3.
Dynamic duty principle of the present invention: when the above-mentioned substrate of glass 1 of light process, high refractive index oxide 2, low-refraction oxide or halogenide 3, metal 4, because the transmission principle of inducing of interference of light principle of stacking and metallic diaphragm has formed a wave band acceptance filter, make wavelength can not pass through, and visible light have high transmittance less than the ultraviolet light of 400nm and wavelength infrared light greater than 700nm.
Good effect of the present invention is that the technology of utilizing vacuum to be coated with multilayer film is coated with multiple layer metal combination of media film in substrate of glass, forms wave band gating optical filter, in efficient inhibition harmful light, makes eyeglass have higher transparency at visible light.Subordinate list is Yixing, Jiangsu protective eye lens factory product and part technical data of the present invention contrast, and therefrom the protective eye lens that as seen utilizes the present invention to make not only can effectivelyly suppress ultraviolet and infrared harmful light, visible light is had transparent preferably again.In addition, by adjusting the parameters such as thickness of rete, can be adjusted, so just can be satisfied the needs of different occasions to the transmission region of product, transmittance and for the inhibition degree of harmful light.Its feature is more thoroughly to stop the injury to human eye of ultraviolet and infrared harmful light, is workman and the ideal order instruments that protect of field man such as steel-making, boiler and welding.
Description of drawings of the present invention:
Fig. 1 is that N of the present invention is 2 o'clock a structural representation
Fig. 2 is the curve of spectrum of the embodiment of the invention
Subordinate list is Yixing, Jiangsu protective eye lens factory product and technical data of the present invention contrast
Embodiments of the invention: substrate of glass 1 adopts JB4 optical glass, high refractive index oxide 2 to adopt titanium dioxide, adopts high refractive index oxide 2 to adopt titanium dioxide low-refraction oxide or halogenide 3 to adopt silicon dioxide, metal 4 to adopt silver, N in the 4th step is chosen as 2, then amount to 9 layer films, its thickness is respectively: 61nm, 164nm, 30nm, 141nm, 40nm, 141nm, 30nm, 164nm, 61nm, and with the protective eye lens curve of spectrum such as Fig. 2 of above parameter manufacturing.
This protective eye lens manufacturing process is as follows: utilize vacuum coating equipment under fine vacuum (10
-2～10
-3Pa) utilize the physical vapour deposition (PVD) film technique on substrate of glass, successively to make as the thin film of above-mentioned structure.
