Description

A kind of aspheric optical lens structure
Technical field
The utility model belongs to optical mirror slip technical field, more particularly to a kind of new aspheric optical lens knot Structure.
Background technology
The development of smart mobile phone is maked rapid progress, and has become a part indispensable in modern life, to camera The requirement of image quality is also higher and 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 with injection moulding process.Wherein the effective portion of optics connects (θ with edge part for angle 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 determines, when non-imaged light reflects or refracts to fillet R1, it is easy to have an impact camera imaging quality Veiling glare, so as to seriously affect 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.
Utility model content
The utility model provides a kind of new aspheric optical lens structure, solves of the prior art aspherical Easily there is the low technical problem of veiling glare image quality in optical mirror slip.
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, having to the effective portion's tangential direction extension of optics is additionally provided between the effective portion of the optics and edge part Imitate footpath extension；The effective portion of optics is connected with 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, is blocked so as to fulfill processing fillet R2 by shading element.
Beneficial effect, by tangentially extending to the effective portion of optics, so that the effective portion of light efficiency and extension Tangent-line transition no longer produces processing fillet, effectively solves the reflection of non-imaged light or refracts to caused spuious during fillet R1 Light.Effective diameter extension and edge part point of intersection diameter D1 ＞ d at the same time, processing fillet R2 are blocked by shading element, 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
To enable the above-mentioned purpose of the utility model, feature and advantage more obvious understandable, below to the utility model Embodiment elaborate.Many details are elaborated in the following description in order to fully understand this practicality It is new.But the utility model can be much to implement different from other manner described here, those skilled in the art can To do similar improvement in the case of without prejudice to the utility model connotation, therefore the utility model is from following public specific real Apply the limitation of mode.
The effective portion 1 of optics connects (θ to embodiment 1 with edge part 2 for angle 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 2 intersection of edge part.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, have an impact camera into As the veiling glare of quality.So as to seriously affect the image quality of camera.The utility model passes through to optics as shown in Figure 4, Figure 5 Eyeglass effective diameter carries out tangential direction extension, and the effective portion 1 of optics and 1.1 junction of effective diameter extension, which smoothly transit not produce, to be added Work fillet, and make tangential direction extension section and edge part point of intersection diameter D1 ＞ d, that is, fillet R2 is processed by the institute of shading element 3 Block；2 points of improvement, edge part fillet are all blocked by shading element, effectively prevent and produced because of Fillet Feature more than Veiling glare, optimize the image quality of camera lens.
The aspheric optical lens structure as shown in Figure 1, Figure 4, Figure 5 of embodiment 2, including the optics for being arranged on centre have Effect portion 1 and the edge part 2 for being arranged on edge, are additionally provided with to the effective portion 1 of optics between the effective portion 1 of the optics and edge part 2 The effective diameter extension 1.1 of tangential direction extension；The effective portion of optics is connected with 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 Caused veiling glare.
The aspheric optical lens structure as shown in Figure 1, Figure 4, Figure 5 of embodiment 3, including the optics for being arranged on centre have Effect portion 1 and the edge part 2 for being arranged on edge, are additionally provided with to the effective portion 1 of optics between the effective portion 1 of the optics and edge part 2 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, is blocked so as to fulfill processing fillet R2 by shading element, avoids non-imaged light from producing here miscellaneous Astigmatism.Veiling glare is effectively prevent under conditions of aspheric optical lens size is not changed, improves camera imaging quality.
