Summary of the invention

The objective of the invention is to overcome the deficiencies in the prior art, provide a kind of make visible light present antiradar reflectivity can clear demonstration colour screen handset interface mobile-phone lens.This mobile-phone lens utilization interference of light principle allows reflective phase cancel each other on the contrary, reduces the reflectivity of mobile phone for visible light, makes the user can more clearly see mobile phone interface.

Another object of the present invention is to provide a kind of method for making of this mobile-phone lens.This method utilization Film Optics principle, be coated with dielectric multi-layer optical thin film at the mobile phone glass interface, visible light interferes on each surface of glass and film and disappears mutually, hardly reflection taking place and sees through film, mobile-phone lens just presents low reflectivity to visible light like this, make people can clearly see mobile phone interface, do not have dizzy sensation.

For solving the problems of the technologies described above, the present invention is achieved by the following technical solutions:

A kind of mobile-phone lens that can clear demonstration colour screen handset interface, comprise a substrate of glass, described substrate of glass upper surface is coated with first low refractive index film that one deck optical thickness is λ/2, be coated with the high refractive index film that one deck optical thickness is λ/2 on first low refractive index film, being coated with one deck optical thickness on the high refractive index film is second low refractive index film of λ/4; Described λ length is between 490～510 nanometers.

Preferably, described λ length is 500 nanometers.

The refractive index of described first low refractive index film, the second low refractive index film material is greater than the refractive index of air, less than the refractive index of glass.

The refractive index of described high refractive index, thin film materials is greater than the refractive index of glass.

Described substrate of glass is the same with glass material with general mobile operator, and its refractive index is 1.71.

Preferably, the material of described first low refractive index film is AL ₂O ₃, its refractive index is 1.6.

Preferably, the material of described second low refractive index film is MgF ₂, its refractive index is 1.38.

Preferably, the material of described high refractive index film is ZrO ₂, its refractive index is 2.1.

The method for making of above-mentioned mobile-phone lens that can clear demonstration colour screen handset interface comprises the steps:

Steps A is first low refractive index film of λ/2 at substrate of glass upper surface plating one deck optical thickness;

Step B, plating one deck optical thickness is the high refractive index film of λ/2 on first low refractive index film again;

Step C, plating one deck optical thickness again on high refractive index film at last is second low refractive index film of λ/4, has plated and has promptly finished making.

The present invention is directed to the general glass mirror design of mobile phone anti-reflection film, make the mobile phone glass interface present low reflectivity for visible light, its reflectivity major part like this can clear demonstration colour screen handset interface all less than 1%.Scientific research is verified, human eye under the situation at photopic vision angle, for yellow, green glow is the most responsive, so central wavelength lambda of the present invention is chosen near 500 nanometers, this wavelength just in time is near the wave spectrum scope of green light.The material of first low refractive index film, second low refractive index film, high refractive index film all is that nature and industry member exist and a large amount of material that uses, and the selection of material is very big, convenient.

The present invention has following beneficial effect:

(1) the present invention uses the interference of light principle, allows reflective phase cancel each other on the contrary, has reduced the reflectivity of mobile phone for visible light greatly, can make the user more clearly see mobile phone interface, uses comfortablely, and effect is good;

(2) the present invention plates three layers of dielectric film on substrate of glass,, control easily for technological processs such as thickness of coating controls, so cost is lower industrialization easily because plated film is the ripe technology of tradition.
