Description
Technical field
The invention belongs to optical mirror slip technical field, more particularly to a kind of new aspheric optical lens structure.
Background technology
The development of smart mobile phone is maked rapid progress, and a part indispensable in modern life is had become, to camera
The requirement of image quality also more and more higher.Aspheric optical lens are the important components of mobile phone camera, by optimizing mirror
Chip architecture improves veiling glare, most important in camera imaging quality is improved.
As shown in figure 1, aspheric optical lens of the prior art mainly include the effective portion of optics and edge part two parts,
It is fabricated by with injection moulding process.Wherein the effective portion of optics and edge part are that angle connects (θ as shown in Figure 2 and Figure 3>0 °), in light
Processing fillet R1 can be produced by learning effective portion and edge part intersection.Optics effective diameter D ＜ shading element internal orifice dimension d, D, d are by optics
The light of system is determined, when non-imaged light reflects or refracts to fillet R1, it is easy to produce influence camera imaging quality
Veiling glare, so as to have a strong impact on the quality of camera in the prior art.And at present in aspheric optical lens technical field also
There is no good method to solve.
The content of the invention
The invention provides a kind of new aspheric optical lens structure, aspherics of the prior art is solved
Easily there is the low technical problem of veiling glare image quality in eyeglass.
Concrete technical scheme is the aspheric optical lens structure, including is arranged on the effective portion of optics and the setting of centre
Edge part at edge, is additionally provided with having to the effective portion's tangential direction extension of optics between the effective portion of optics and edge part
Imitate footpath extension；The effective portion of optics and the connection of effective diameter extension tangent line, that is, the effective portion of optics and effective diameter extension
Portion intersection does not produce processing fillet；The effective diameter extension is connected with edge part angle, produces processing fillet R2.
The effective diameter extension and edge part point of intersection diameter D1 ＞ d, i.e., prolonged by the tangential direction in the effective portion of optics
Stretching makes to move outside processing fillet, so as to realize that processing fillet R2 is blocked element and blocked.
Beneficial effect, by tangentially extending to the effective portion of optics, so that the effective portion of optics and extension
Tangent-line transition no longer produces processing fillet, effectively solves the reflection of non-imaged light or refracts to produced spuious during fillet R1
Light.Effective diameter extension and edge part point of intersection diameter D1 ＞ d simultaneously, processing fillet R2 are blocked element and blocked, it is to avoid it is non-into
As light produces veiling glare here.Veiling glare is effectively prevent under conditions of aspheric optical lens size is not changed, is carried
High camera imaging quality.

Embodiment
In order to facilitate the understanding of the purposes, features and advantages of the present invention, specific reality below to the present invention
The mode of applying elaborates.Many details are elaborated in the following description to fully understand the present invention.But this
Invention can be implemented with being much different from other manner described here, and those skilled in the art can be without prejudice to the present invention
Similar improvement is done in the case of intension, therefore the present invention is not limited by following public embodiment.
The effective portion 1 of optics and edge part 2 are that angle connects (θ to embodiment 1 in the prior art as shown in Figure 1, Figure 2, Figure 3 shows>
0 °), processing fillet R1 can be produced in the effective portion 1 of optics and the intersection of edge part 2.Optics effective diameter D ＜ shading element internal orifice dimensions
D, when non-imaged light reflects or when refracting to fillet R1, R1 surfaces do not have shading element 3 to cover, produce influence camera into
As the veiling glare of quality.So as to have a strong impact on the image quality of camera.The present invention is by optical mirror slip as shown in Figure 4, Figure 5
Effective diameter carries out tangential direction extension, and the effective portion 1 of optics and the junction of effective diameter extension 1.1, which smoothly transit, does not produce processing circle
Angle, and make tangential direction extension and edge part point of intersection diameter D1 ＞ d, i.e., processing fillet R2 is blocked element 3 and blocked；
2 points of improvement more than, edge part fillet is all blocked element and blocked, and effectively prevent produced by Fillet Feature miscellaneous
Astigmatism, optimizes the image quality of camera lens.
The aspheric optical lens structure as shown in Figure 1, Figure 4, Figure 5 of embodiment 2, including be arranged on the optics of centre and have
Effect portion 1 and the edge part 2 for being arranged on edge, are additionally provided between the effective portion 1 of optics and edge part 2 to the effective portion 1 of optics
The effective diameter extension 1.1 of tangential direction extension；The effective portion of optics and the connection of effective diameter extension tangent line, that is, optics
Effective portion and effective diameter extension intersection do not produce processing fillet, when effectively solving the reflection of non-imaged light or refracting to fillet
Produced veiling glare.
The aspheric optical lens structure as shown in Figure 1, Figure 4, Figure 5 of embodiment 3, including be arranged on the optics of centre and have
Effect portion 1 and the edge part 2 for being arranged on edge, are additionally provided between the effective portion 1 of optics and edge part 2 to the effective portion 1 of optics
The effective diameter extension 1.1 of tangential direction extension；The effective diameter extension 1.1 is connected with edge part angle, produces processing circle
Angle R2.The effective diameter extension 1.1 and edge part point of intersection diameter D1 ＞ d, i.e., prolonged by the tangential direction in the effective portion of optics
Stretching makes to move outside processing fillet, so as to realize that processing fillet R2 is blocked element and blocked, it is to avoid non-imaged light produces miscellaneous here
Astigmatism.Veiling glare is effectively prevent under conditions of aspheric optical lens size is not changed, camera imaging quality is improved.
