Description
Technical field
The present invention relates to optical field, and in particular to a kind of eyeglass and its manufacture method for eliminating veiling glare.
Background technology
With the continuous progress of science and technology, the function of smart mobile phone is more and more comprehensive, and camera function turns into non-in smart mobile phone
Chang Guanjian One function, but veiling glare is often produced on the eyeglass of mobile phone.
Wherein veiling glare is the general name of improper transmission light in optical system, result from light leak, light-transparent optical surface it is residual
The residual reflectivity of the Non-optical surfaces such as coreflection and lens barrel inwall, can cause the decay of imaging system performance, make the modulation of camera lens
Transmission function declines, and endangers the image quality of camera lens, is embodied in imaging definition reduction, and level is reduced, color saturation drop
It is low.
Fig. 1 gives the sectional view of existing mobile-phone lens, and the eyeglass is plastic aspherical element eyeglass.Can from Fig. 2 and Fig. 3
To find out that existing mobile-phone lens eliminate veiling glare not fully.
Plastic aspherical element lens design clip and flange face the sandblasting extensive use in lens mechanism design, by right
Lens surface carries out blasting treatment and eliminates a part of veiling glare, but sandblast technology has a disadvantage that：1) eyeglass clip side nothing
Method sandblasting；2) invalid footpath and the more difficult control of effective diameter critical part sandblast technology；3) existing sandblast technology, compares and is difficult to ensure card eyeglass
Assemble plane sandblasting face precision fine；4) light is mapped to sandblasting face and can break up light, and some light broken up can be by certain
The refraction and reflection aggregation of angle are fallen in image planes, so as to produce veiling glare.
The content of the invention
The mirror for eliminating veiling glare low, that the spuious light effect of suppression is good is required sandblasting it is an object of the invention to provide a kind of
Piece.
It is a further object to provide the manufacture method of above-mentioned eyeglass.
The technical solution adopted in the present invention is, a kind of eyeglass for eliminating veiling glare, including eyeglass, in the eyeglass
The heart is non-spherical surface, it is characterised in that the edge of the eyeglass is ring flange, and the color of the center and peripheral of the eyeglass is not
Together.
The features of the present invention is also resided in,
The color at the center of the eyeglass is more of light color than edge.
The center of the eyeglass it is transparent, the color at edge is black.
It is APEL series, E48R, S3810, K26R, 330R, EP series or ZEONEX480 that the material of the eyeglass, which is used,
Optical material.
A kind of manufacture method for the eyeglass for eliminating veiling glare, comprises the following steps：
1) raw material of the manufacture aspherical lens of two kinds of colors is provided；
2) two plasticizing injecting devices, respectively plasticizing injecting device A and plasticizing injecting device B, two plasticizing notes are provided
Injection device respectively loads a kind of raw material of the manufacture aspherical lens of color；
3) eyeglass of veiling glare can be eliminated by being molded by using double-shot moulding method.
Double-shot moulding method is plasticizing injecting device A and plasticizing injecting device B is successively penetrated two kinds of materials in the step 3
Go out to constitute and can eliminate the eyeglass of veiling glare.
In the step 3 in injection moulding process, material is first injected into small cavity aftershaping, Zhi Houkai with plasticizing injecting device A
Mould but do not eject, matched moulds after mould rotation 180 degree, another material is injected with plasticizing injecting device B be marked with the afterwards
A kind of big chamber of material, second of die sinking ejection, the complete eyeglass for eliminating veiling glare after such two kinds of materials stick together
Complete
The beneficial effects of the invention are as follows the eyeglass that the present invention can eliminate veiling glare uses center of lens and two kinds of edge face
Color, can effectively suppress veiling glare, improve camera in the quality of picture of taking pictures；The present invention can eliminate the system of the eyeglass of veiling glare
Make the eyeglass of method manufacture, lens edge requires relatively low to sandblast technology.
