Abstract
A method to control low reflection and transmission colour for multilayer film spectacles lens which are formed with low reflection of selectivity colour by utilizing with light absorption material sticks the electrolyte having low reflection rate and high reflection rate in cross on the plastics spectacles lens with hard film coatings and inserts the film with light adsorption properties to form the multilayer film spectacles lens with low reflection of the selectivity colour.
Description
Technical field
The present invention relates to use the light absorption material, form the low reflection multilayer film lens of selectivity color and the method for low reflection of control and transmitted colors.
Background technology
Traditional lens multilayer film technology is to coat the material with refractive index on the substrate of glass or plastic cement material in order, adds functions such as low reflection, high reflection or bandpass filtering.
Glass sheet as shown in Figure 1, average reflectance is generally about 4%.Paste low-refraction material SiO in order repeatedly 22 times
2With high index of refraction material ZrO
2, make it can 100% reflection in wavelength coverage of 460-580nm.This bonding method is called highly-reflective coating.Reducing reflectivity in contrast to greatest extent, is purpose according to increasing transmissivity with the reflectivity that reduces.This bonding method is called low reflectance coating.
The result of low reflectance coating, as shown in Figure 2.Low reflectance coating also is to intersect to paste SiO
2And ZrO
2Two kinds of materials are adjusted dielectric stickup thickness and adjustment order suitably according to application target.Consequently when the on glass stickup dielectric of reflectivity more than 4%, can reduce reflectivity below 2%, so average reflection reduces, reach the good effect of transmission.The method that general lens is pasted with above-mentioned low reflection multilayer reduces reflectivity, guarantees transmissivity more than the eyeglass before pasting.
But in order to make lens improve luminous transparency to greatest extent, be designed to low reflection, can cause selecting look to limit to very much, can not satisfy the modern's of pursuing individuality demand.When improving transmission in addition, though vividness is fine, externally use is not free in the environment, even the technical ability of protection eyes is not enough.
Fig. 3 is that expression utilizes the colouring mode to form the procedure chart of color.Luminous transparency by glasses can reduce, transmission be not natural light, but add the pigment of glasses to.The above-mentioned method that forms color according to colouring is, dyestuff is directly permeated method on the lens surface.This method is the manual work of dying (Dipping) by dripping, and is now very universal.
This product has reflectivity or transmitted colors is inhomogeneous, the shortcoming that work efficiency descends greatly.Especially on the characteristics of dyestuff of painting, be dropped in the absorbing agent of eyeglass, owing to having under the external environment condition of light between long-term, the generation rerum natura changes, the variation of absorbing wavelength, therefore cause the variation of variable color and Transflective, reduce the adherence force between the coated film interface, hinder the permanance between each coated film.
Though the present patent application people can solve on the method for utilizing existing absorbing agent to form color, improved and do not comprised absorbing agent substantially, only utilized the Korean Patent 2001-0073886 of dielectric wavelength characteristic " forming the multilayer film lens of selectivity color and the method for control color ".But foregoing invention is only utilized dielectric wavelength characteristics, forms the selectivity color, and the no reflection events control that therefore has glasses user side not too is easy to shortcoming.
In addition; form metal film; use the metal film bonding method of low-refraction dielectric thereon as protective seam; though the characteristic of transmitted colors is outstanding; but the user uses the face (front of eyeglass; the back) reflection is increased, and causes the user's offside reflection and the virtual image, therefore has the shortcoming that a lot of obstacles are arranged for the visual field.
So the present inventor has developed method of the present invention.For the color that improves the user side simultaneously forms and no reflection events control, use suitable light absorption material at the lens concave surface.When only being to use the light absorption material, for the shortcoming that the reflectance that remedies eyeglass front and back increases, the auxiliary stickup of dielectric, control reduces forward and backward reflection.
Summary of the invention
Traditional colour lens only utilizes colouring dyestuff or dielectric wavelength characteristic, forms color.Different therewith, under the high vacuum situation, pasted dielectric among the present invention with high index of refraction and low-refraction in convex surface multilayer intersection, form multilayer film.Paste light absorption material and dielectric in the concave surface intersection, obtained required transmitted colors and low reflecting effect simultaneously.Suitably utilize the multi-angle color change, form the sensation that meets consumer's clothes, the selectivity color that meets usefulness such as driver at night, work, leisure.Low reflection multilayer film lens is provided.
The present invention has on the lens convex surface of dura mater coating in order to obtain any color of visible rays scope, forms the low reflection strength that constitutes with 5 layers of thin dielectric rete.Especially on concave surface, paste by the 3 layers of thin dielectric rete that constitutes-light absorption substance film layer-thin dielectric rete.Therefore increase the low reflection of side scope and the assimilation effect of absorbing material to the user.Adjust dielectric kind and put in order, the thickness of thin layer, control the method for desired reflection colour and transmitted colors and the low reflection of control simultaneously.

In order to achieve the above object, the present invention has on the plastic spectacles sheet of dura mater coating, intersects to have pasted the dielectric with low-refraction and high index of refraction, forms the multilayer film lens of selectivity color.
The multilayer film lens of above-mentioned selectivity color is characterised in that to have dura mater coating 2a, on the plastic spectacles sheet 1 of 2b.
By the ion beam-assisted method of attaching of high vacuum, pasted low-refraction thin dielectric rete 3a in the convex surface intersection, 5a, 7a and high index of refraction thin dielectric rete 4a, 6a, the antiradar reflectivity wavelength of formation visible rays scope.Intersect at concave surface and to have pasted low-refraction thin dielectric rete 3b, 5b and light absorption material 9 are obtained and are wanted the transmitted colors that obtains.Simultaneously, on to greatest extent, reduced the reflectivity of concave surface.
The present invention forms reflection colour by following structure.On the convex surface of above-mentioned lens, in can the wavelength of visible rays scope, on selected any wavelength, play high reflex, constitute by the thin dielectric rete that on dura mater, has the light reflection function and thin dielectric rete that increases reflection strength and the thin dielectric rete that forms required color.
The method of control transmitted colors and low reflection, it comprises following step:
On concave surface, paste in the wavelength of transmission convex surface, absorb the light absorption material of any range of wavelength, form transmitted colors.Simultaneously,, the light absorption material is clipped in the middle, intersects and paste the low-refraction thin dielectric film, on to greatest extent, reduce forward and backward reflectivity of lens in order to reduce the increase of reflectivity to greatest extent.
Action principle according to the reflection colour and the transmitted colors of multilayer film lens of the present invention are represented is described as follows with reference to the accompanying drawings.
As the glass or the plastic cement of substrate, the reflectivity in the visible rays scope of 400-700nm is about the same, can not observe particular color.Different therewith is, when multilayer was pasted thin dielectric film, the reflection wavelength of every wavelength band was all different, and the color of each wavelength band according to the reflection coefficient of its wavelength, stimulates to eyes with reflection strength to observe color.For example, during low reflection multilayer film among Fig. 2, other wavelength height of the relative reflectance of 520nm is green so the observer sees.
(for example, metal) situation can find out that as Fig. 4 forward and backward reflectivity of eyeglass increases greatly only to use the light absorption material.This material major part is used in high reflection mirror or half wave mirror (half-mirror) etc.The such stickup transmissivity and the characteristic of reflectivity, shown in Figure 5.
But as shown in Figure 6, the eye plate concave surface forms film according to the high vacuum technology for applying of light absorption material, obtains the optical absorption of specific wavelength correspondence among the present invention.Simultaneously, intersect and paste the dielectric low reflection layer of low-refraction, it is interacted, on to greatest extent, control the reflection of forward and backward of eyeglass, reduce user's visual field burden.Fig. 7 after expression is pasted according to the principle of the invention, is controlled at the front of eyeglass, the reflectivity Characteristics of back.When paste absorbing the material of 600nm extent and scope on the eyeglass, though the incident light FR wavelength that is visible rays when transmissive side surfaces is seen, is just kept the luminosity of 600nm scope.If this transmissivity is suitably adjusted, can obtain transmitted colour and low reflecting effect simultaneously.
Like the present invention pastes the light absorption material between thin dielectric film, can reduce the existing dielectric multilayer that only uses to greatest extent and paste and problem such as adherence force between the film that produces.Double to increase permanance, form the high vacuum film, the rerum natura that reduces to greatest extent along with the time changes, and can improve existing colouring eyeglass and reach the shortcoming of only using dielectric eyeglass.
