Description

Technical Field

[0001] The present application relates to the field of optical elements, and in particular, to a camera lens assembly. Background Art

[0002] At present, the market for portable electronic products such as mobile phones has higher and higher requirements for camera quality. Basically, every mobile phone is equipped with at least one large-aperture camera. The larger the aperture of the camera, the more light passes through the camera per unit time, and the clearer the image.

[0003] Generally, the larger the aperture of a camera, the smaller its F number. However, as the F number decreases, especially when the F number is in the range of 1.2-1.5, the first few lenses in the camera lens group will become very large and very sensitive, resulting in conventional processing and assembly capabilities being unable to meet the mass production requirements in actual production.

[0048] Unless otherwise defined, all terms (including technical terms and scientific terms) used in this article have the same meaning as those commonly understood by ordinary technicians in the field to which this application belongs. It should also be understood that terms (such as terms defined in commonly used dictionaries) should be interpreted as having the same meaning as their meaning in the context of the relevant technology, and will not be interpreted in an idealized or overly formal sense unless explicitly defined in this article.

[0049] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0050] The features, principles and other aspects of the present application are described in detail below.

[0051] The camera lens set according to the exemplary embodiment of the present application may include six lenses with optical power, namely a first lens, a second lens, a third lens, a fourth lens, a fifth lens and a sixth lens. The six lenses are arranged in sequence from the object side to the image side along the optical axis. Any two adjacent lenses from the first lens to the sixth lens may have a spacing distance between them.

[0052] In an exemplary embodiment, the first lens may have positive optical power, and its object side surface may be convex; the second lens may have positive optical power or negative optical power, and its object side surface may be convex; the third lens may have negative optical power, and its image side surface may be concave; the fourth lens may have positive optical power or negative optical power, and its object side surface may be convex, and its image side surface may be concave; the fifth lens may have negative optical power, and its object side surface may be convex, and its image side surface may be concave; and the sixth lens may have positive optical power, and its object side surface may be convex, and its image side surface may be concave.

[0053] In an exemplary embodiment, a first lens with positive optical power and a third lens with negative optical power cooperate with a fifth lens with negative optical power and a sixth lens with positive optical power, which can help the camera lens group to increase the F number while maintaining a good light convergence effect. At the same time, the limited surface shape combination can enable the camera lens group to have a better correction effect on aberrations to obtain higher imaging quality.

[0054] In an exemplary embodiment, the camera lens assembly according to the present application may satisfy: Fno<1.40, where Fno is the F number of the camera lens assembly. Satisfying Fno<1.40 allows the lens assembly to maintain a smaller F number, making its features more obvious.

[0055] In an exemplary embodiment, the camera lens assembly according to the present application may satisfy: 1.00<f6 / f<3.00, where f is the total effective focal length of the camera lens assembly, and f6 is the effective focal length of the sixth lens. More specifically, f6 and f may further satisfy: 1.20<f6 / f<3.00. Satisfying 1.00<f6 / f<3.00 can not only improve the aberration correction capability of the camera lens assembly, but also avoid excessive concentration of light focal length on the sixth lens, thereby facilitating reduction of the sensitivity of the sixth lens.

[0056] In an exemplary embodiment, the camera lens assembly according to the present application may satisfy: 1.00<f5 / f34<3.00, wherein f5 is the effective focal length of the fifth lens, and f34 is the combined focal length of the third lens and the fourth lens. More specifically, f5 and f34 may further satisfy: 1.30<f5 / f34<2.40. Satisfying 1.00<f5 / f34<3.00 is conducive to obtaining a more reasonable optical power distribution of the camera lens assembly, and is conducive to reducing the overall sensitivity of the camera lens assembly, and improving the production yield of the camera lens assembly.

[0057] In an exemplary embodiment, the camera lens group according to the present application may satisfy: 1.00<R12 / R11<4.00, wherein R11 is the radius of curvature of the object side surface of the sixth lens, and R12 is the radius of curvature of the image side surface of the sixth lens. More specifically, R12 and R11 may further satisfy: 1.40<R12 / R11<4.00. Satisfying 1.00<R12 / R11<4.00 can help the camera lens group to maintain good imaging quality of the central light while avoiding problems such as imaging blur caused by excessive curvature of the image side surface of the sixth lens, so as to improve the imaging quality of the camera lens group in the central area.

[0058] In an exemplary embodiment, the camera lens assembly according to the present application may satisfy: 2.00<(R9+R10) / (R9-R10)<5.00, wherein R9 is the radius of curvature of the object side surface of the fifth lens, and R10 is the radius of curvature of the image side surface of the fifth lens. More specifically, R9 and R10 may further satisfy: 2.00<(R9+R10) / (R9-R10)<4.50. Satisfying 2.00<(R9+R10) / (R9-R10)<5.00 can not only make the edge field of view have better imaging quality, but also ensure the processability of the edge area of ​​the lens.

[0059] In an exemplary embodiment, the camera lens assembly according to the present application may satisfy: 10.00<CT1 / T23<20.00, wherein CT1 is the center thickness of the first lens on the optical axis, and T23 is the spacing distance between the second lens and the third lens on the optical axis. More specifically, CT1 and T23 may further satisfy: 10.00<CT1 / T23<18.60. Satisfying 10.00<CT1 / T23<20.00 helps to ensure that the camera lens assembly has a good distortion correction effect while also helping to shorten the overall size of the camera lens assembly, avoiding the overall size being too large and unsuitable for the current trend of ultra-thinness in the market for portable electronic products such as mobile phones.

[0060] In an exemplary embodiment, the camera lens assembly according to the present application may satisfy: 18.00<T45 / T12<27.00, wherein T12 is the spacing distance between the first lens and the second lens on the optical axis, and T45 is the spacing distance between the fourth lens and the fifth lens on the optical axis. Satisfying 18.00<T45 / T12<27.00 can not only ensure that the camera lens assembly has a good distortion correction effect, but also avoid problems such as the lens barrel design caused by the excessive gap between the fourth lens and the fifth lens, which helps to improve the applicability of the camera lens assembly.

[0061] In an exemplary embodiment, the camera lens assembly according to the present application may satisfy: 1.00<(SAG31+SAG32) / (SAG32-SAG31)<3.00, wherein SAG31 is the distance from the intersection of the object side surface of the third lens and the optical axis to the effective radius vertex of the object side surface of the third lens on the optical axis, and SAG32 is the distance from the intersection of the image side surface of the third lens and the optical axis to the effective radius vertex of the image side surface of the third lens on the optical axis. More specifically, SAG31 and SAG32 may further satisfy: 1.50<(SAG31+SAG32) / (SAG32-SAG31)<3.00. Satisfying the condition 1.00<(SAG31+SAG32) / (SAG32-SAG31)<3.00 can not only ensure that the third lens has a better effect on correcting the aberration of the camera lens group, but also effectively avoid problems such as deterioration of the processability and increased sensitivity of the third lens, which is more conducive to the later processing of the lens group and is of great help in improving the overall imaging quality and production yield of the camera lens group.

[0062] In an exemplary embodiment, the camera lens assembly according to the present application may satisfy: 35.00<(DT11+DT12) / (DT11-DT12)<42.00, wherein DT11 is the maximum effective radius of the object side of the first lens, and DT12 is the maximum effective radius of the image side of the first lens. Satisfying 35.00<(DT11+DT12) / (DT11-DT12)<42.00 can further reduce the F number of the camera lens assembly and control the processability of the first lens.

[0063] In an exemplary embodiment, the camera lens assembly according to the present application may satisfy: 1.00<ET6 / ET2<3.00, where ET2 is the edge thickness of the second lens, and ET6 is the edge thickness of the sixth lens. Satisfying 1.00<ET6 / ET2<3.00 is beneficial for correcting the aberration of the central light and improving the light convergence ability of the edge field of view, thereby improving the overall imaging quality of the camera lens assembly.

[0064] In an exemplary embodiment, the camera lens group according to the present application may satisfy: 3.00<f12 / BFL<5.00, wherein f12 is the combined focal length of the first lens and the second lens, and BFL is the distance on the optical axis from the image side of the sixth lens to the imaging surface of the camera lens group. More specifically, f12 and BFL may further satisfy: 3.50<f12 / BFL<4.70. Satisfying 3.00<f12 / BFL<5.00 can avoid excessive concentration of the focal length of the camera lens group on the first two lenses, while avoiding many problems in the later modules caused by too small or too large back focal length (BFL) of the camera lens group.

[0065] In an exemplary embodiment, the camera lens assembly according to the present application further includes an aperture provided between the object side and the first lens. Optionally, the camera lens assembly may further include a filter for correcting color deviation and / or a protective glass for protecting a photosensitive element located on the imaging surface.

[0066] The present application proposes a camera lens set with the characteristics of miniaturization, ultra-small F number, telephoto, high resolution and high imaging quality. The camera lens set according to the above-mentioned embodiment of the present application can use multiple lenses, such as the six lenses mentioned above. By reasonably allocating the focal length, surface shape, center thickness of each lens and the on-axis spacing between each lens, etc., the incident light can be effectively converged, the total optical length of the imaging lens can be reduced, and the processability of the imaging lens can be improved, making the camera lens set more conducive to production and processing.

[0067] In the embodiment of the present application, at least one of the mirror surfaces of each lens is an aspherical mirror surface, that is, at least one of the mirror surfaces from the object side of the first lens to the image side of the sixth lens is an aspherical mirror surface. The characteristic of the aspherical lens is that the curvature changes continuously from the center of the lens to the periphery of the lens. Unlike a spherical lens with a constant curvature from the center of the lens to the periphery of the lens, an aspherical lens has a better curvature radius characteristic, and has the advantages of improving distortion aberration and improving astigmatism aberration. After adopting an aspherical lens, the aberration occurring during imaging can be eliminated as much as possible, thereby improving the imaging quality. Optionally, at least one of the object side and image side of each lens in the first lens, the second lens, the third lens, the fourth lens, the fifth lens and the sixth lens is an aspherical mirror surface. Optionally, the object side and image side of each lens in the first lens, the second lens, the third lens, the fourth lens, the fifth lens and the sixth lens are all aspherical mirror surfaces.

[0068] However, those skilled in the art should understand that, without departing from the technical solution claimed in the present application, the number of lenses constituting the camera lens group can be changed to obtain the various results and advantages described in this specification. For example, although six lenses are described as an example in the embodiment, the camera lens group is not limited to including six lenses. If necessary, the camera lens group may also include other numbers of lenses.

[0069] Specific embodiments of the camera lens assembly applicable to the above-mentioned embodiments will be further described below with reference to the accompanying drawings.

[0073] The first lens E1 has positive focal power, and its object side surface S1 is convex, and its image side surface S2 is concave.
