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] Currently, camera lens assemblies used in mobile electronic devices, such as smartphones, often feature a high Fno (Fn) of 2.0 or higher to achieve excellent optical performance. However, in low-light conditions, these high Fn can no longer meet diverse shooting needs, especially for capturing night scenes in low illumination.

[0003] Generally speaking, the larger the aperture of a lens, the more light it lets in. In low-light environments, a large aperture provides better brightness, reducing exposure time and enabling night photography, meeting the demands of increasingly diverse shooting conditions. However, large-aperture lenses often have large diameters, which can lead to longer lens sizes, contradicting the ultra-thin lens designs that users seek.

[0004] Therefore, how to make the lens group have the characteristics of large aperture and ultra-thinness at the same time is one of the difficult problems that many lens designers urgently need to solve. Summary of the Invention

It should also be understood that terms (such as those defined in commonly used dictionaries) should be interpreted as having a meaning consistent with their meaning in the context of the relevant technology and will not be interpreted in an idealized or overly formal sense unless expressly defined as such herein.

[0042] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this 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.

[0043] The features, principles and other aspects of the present application are described in detail below.

[0044] The camera lens assembly according to an exemplary embodiment of the present application may include seven lenses having optical power, namely a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens, and a seventh lens. These seven lenses are arranged in order from the object side to the image side along the optical axis. Any two adjacent lenses among the first through seventh lenses may be spaced apart by a distance.

[0045] In an exemplary embodiment of the present application, the first lens may have positive or negative optical power; the second lens may have positive or negative optical power; the third lens may have positive optical power, and its object-side surface may be convex; the fourth lens may have negative optical power, and its image-side surface may be concave; the fifth lens may have negative optical power; the sixth lens may have positive or negative optical power; and the seventh lens may have positive or negative optical power.

[0046] In an exemplary embodiment, the camera lens assembly according to the present application may satisfy the following conditions: TTL / ImgH<1.5, 0<(CT1-CT5) / (T34-T23)<1.5, 0.85<CT5 / CT3<2.5, and f / EPD<1.8, wherein ImgH is half of the diagonal length of the effective pixel area on the imaging plane of the camera lens assembly, TTL is the distance from the object side surface of the first lens to the imaging plane of the camera lens assembly on the optical axis, CT1 is the center thickness of the first lens on the optical axis, CT3 is the center thickness of the third lens on the optical axis, CT5 is the center thickness of the fifth lens on the optical axis, T23 is the air spacing between the second lens and the third lens on the optical axis, T34 is the air spacing between the third lens and the fourth lens on the optical axis, f is the total effective focal length of the camera lens assembly, and EPD is the entrance pupil diameter of the camera lens assembly. More specifically, CT1, CT5, T34, T23, and CT3 may further satisfy: 0.5<(CT1-CT5) / (T34-T23)<1.0 and 1.0<CT5 / CT3<2.0.

[0047] In this application, by reasonably setting the seven lenses and the optical focal length and surface shape of the lenses, and matching TTL / ImgH<1.5, 0<(CT1-CT5) / (T34-T23)<1.5, 0.85<CT5 / CT3<2.5 and f / EPD<1.8, the camera lens group provided in this application can have characteristics such as large aperture and ultra-thinness. For example, by constraining the ratio of the on-axis distance from the object side of the first lens to the image plane of the camera lens group to the size of the imaging surface, it is beneficial to achieve ultra-thin characteristics, which can meet the needs of assembling the camera lens group in the limited installation space of electronic products such as mobile phones. At the same time, by reasonably setting the center thickness of the lens and the air gap between the lenses along the optical axis, the lenses can be reasonably distributed, which is beneficial to achieving large image surface, ultra-thinness and other characteristics while improving the resolution of the lens group, and is beneficial to improving the machinability of each lens. By constraining the ratio of the total effective focal length of the lens group to the entrance pupil diameter, the aperture of the lens group can be larger and the amount of light entering is more, which is beneficial to achieving characteristics such as large aperture of the lens group, effectively increasing the shutter speed in dark environments, and improving the shooting effect of details.

[0048] In an exemplary embodiment, the camera lens assembly according to the present application may satisfy the following: 0≤(f1+f2+f3) / f123<3, where f1 is the effective focal length of the first lens, f2 is the effective focal length of the second lens, f3 is the effective focal length of the third lens, and f123 is the combined focal length of the first lens, the second lens, and the third lens. More specifically, f1, f2, f3, and f123 may further satisfy the following: 0.5≤(f1+f2+f3) / f123<2.0. Satisfying 0≤(f1+f2+f3) / f123<3 allows for balancing aberrations between lenses and lens groups by properly allocating the power of the lenses and lens groups, thereby improving imaging quality.

[0049] In an exemplary embodiment, the camera lens assembly according to the present application may satisfy the following conditions: -1<f7 / f6<0 and 0<R11 / (R13+R14)<1.5, wherein f6 is the effective focal length of the sixth lens, f7 is the effective focal length of the seventh lens, R11 is the radius of curvature of the object side surface of the sixth lens, R13 is the radius of curvature of the object side surface of the seventh lens, and R14 is the radius of curvature of the image side surface of the seventh lens. More specifically, R11, R13, and R14 may further satisfy the following conditions: 0<R11 / (R13+R14)<1.0. Satisfying -1<f7 / f6<0 and 0<R11 / (R13+R14)<1.5 can reduce the excessive curvature of the surface of the sixth lens and the seventh lens, thereby facilitating the reduction of the surface optical sensitivity of the sixth lens and the seventh lens, facilitating the molding of the sixth lens and the seventh lens, and improving the surface stability of the two lenses.

[0050] In an exemplary embodiment, the camera lens assembly according to the present application may satisfy the following relationship: 0 < f4 / f5 < 3, where f4 is the effective focal length of the fourth lens element and f5 is the effective focal length of the fifth lens element. More specifically, f4 and f5 may further satisfy the following relationship: 0 < f4 / f5 < 2. This relationship, 0 < f4 / f5 < 3, can improve the resolution of the lens assembly by properly allocating the effective focal lengths of the fourth and fifth lenses.

[0051] In an exemplary embodiment, the camera lens assembly according to the present application may satisfy the following conditions: -4<(R8+R10) / f45<0, where R8 is the radius of curvature of the image side surface of the fourth lens, R10 is the radius of curvature of the image side surface of the fifth lens, and f45 is the combined focal length of the fourth and fifth lenses. More specifically, R8, R10, and f45 may further satisfy the following conditions: -3<(R8+R10) / f45<0. By satisfying -4<(R8+R10) / f45<0, the aberrations of the lens assembly can be reduced, the imaging quality of the lens assembly can be improved, and the processing difficulty can be reduced by controlling the ratio of the radius of curvature of the fourth and fifth lenses to the combined focal length of the fourth and fifth lenses.

[0052] In an exemplary embodiment, the camera lens assembly according to the present application may satisfy the following condition: 0.2 < ET7 / CT7 < 1.5, where CT7 is the center thickness of the seventh lens element on the optical axis, and ET7 is the edge thickness of the seventh lens element. This condition allows for an ultra-thin lens assembly by constraining the center thickness of the seventh lens element on the optical axis and its edge thickness within a reasonable range, while also improving the processability of the seventh lens element.

[0053] In an exemplary embodiment, the camera lens assembly according to the present application may satisfy the following conditions: -8<SAG72 / CT7+SAG71 / T67<-2, where SAG71 is the distance on the optical axis from the intersection of the object-side surface of the seventh lens and the optical axis to the vertex of the effective radius of the object-side surface of the seventh lens, SAG72 is the distance on the optical axis from the intersection of the image-side surface of the seventh lens and the optical axis to the vertex of the effective radius of the image-side surface of the seventh lens, CT7 is the center thickness of the seventh lens on the optical axis, and T67 is the air spacing on the optical axis between the sixth and seventh lenses. Satisfying -8<SAG72 / CT7+SAG71 / T67<-2 allows for effective control of the principal ray deflection angle of the lens assembly by properly controlling the profile sag of the object-side and image-side surfaces of the seventh lens, the center thickness of the seventh lens, and the air spacing between the sixth and seventh lenses, while also facilitating better processability of the profile of the seventh lens.

[0054] In an exemplary embodiment, the object side surface of the first lens is convex and the image side surface is concave; the object side surface of the second lens is convex and the image side surface is concave. According to the camera lens group of the present application, the following conditions can be satisfied: 0.5<(R1+R2) / (R3+R4)<2.5, where R1 is the radius of curvature of the object side surface of the first lens, R2 is the radius of curvature of the image side surface of the first lens, R3 is the radius of curvature of the object side surface of the second lens, and R4 is the radius of curvature of the image side surface of the second lens. More specifically, R1, R2, R3 and R4 can further satisfy: 1.0<(R1+R2) / (R3+R4)<2.0. The present application reasonably sets the surface shape of the first lens and the second lens and matches 0.5<(R1+R2) / (R3+R4)<2.5, which is beneficial to reducing the sensitivity of the lens group by reasonably allocating the surface shape and curvature radius of the first lens and the second lens, and is also beneficial to improving the resolution of the lens group and making the lens group have good processability.

[0055] In an exemplary embodiment, the camera lens assembly according to the present application may satisfy the following relationship: 1 < ET4 / ET5 < 4, where ET4 is the edge thickness of the fourth lens, and ET5 is the edge thickness of the fifth lens. This 1 < ET4 / ET5 < 4 relationship allows for easier injection molding of the fourth and fifth lenses by controlling their edge thicknesses within a reasonable range, thereby improving the workability of the lens assembly.

[0056] In an exemplary embodiment, the camera lens assembly according to the present application may satisfy the following relationship: 0 < R5 / f3 - R8 / f4 < 2, where f3 is the effective focal length of the third lens element, f4 is the effective focal length of the fourth lens element, R5 is the radius of curvature of the object-side surface of the third lens element, and R8 is the radius of curvature of the image-side surface of the fourth lens element. Satisfying 0 < R5 / f3 - R8 / f4 < 2 facilitates controlling the angle of incidence of off-axis field rays on the imaging plane, enabling the camera lens assembly to have a relatively suitable chief ray angle while maintaining a relatively short overall length, thereby facilitating improved compatibility between the lens assembly and the photosensitive element.

[0057] In an exemplary embodiment, the camera lens assembly according to the present application may satisfy the following conditions: 0 < (CT2 + CT4) / CT5 < 1.8, where CT2 is the center thickness of the second lens on the optical axis, CT4 is the center thickness of the fourth lens on the optical axis, and CT5 is the center thickness of the fifth lens on the optical axis. Satisfying 0 < (CT2 + CT4) / CT5 < 1.8 reduces the optical thickness sensitivity of the second, fourth, and fifth lenses by constraining the ratio of their center thicknesses on the optical axis, facilitating mass production.

[0058] In an exemplary embodiment, the sixth lens has positive optical power, and its object-side surface is convex; the seventh lens has negative optical power, and its image-side surface is concave. The camera lens assembly according to the present application can satisfy: 0<CT7 / CT6<1, wherein CT6 is the center thickness of the sixth lens on the optical axis, and CT7 is the center thickness of the seventh lens on the optical axis. By reasonably setting the optical power and surface features of the sixth lens and the seventh lens, and combining 0<CT7 / CT6<1, the present application can reasonably constrain the center thickness of the sixth lens and the seventh lens, so that the light can transition smoothly during the propagation process, thereby helping to balance the out-of-field aberrations and improve the edge resolution.

[0059] In an exemplary embodiment, the camera lens assembly according to the present application may satisfy the following condition: 1.05 ≤ BFL / T67 < 3, where T67 is the air spacing between the sixth and seventh lenses on the optical axis, and BFL is the distance on the optical axis from the image side surface of the seventh lens to the imaging plane of the camera lens assembly. Meeting 1.05 ≤ BFL / T67 < 3 increases the distance on the optical axis from the image side surface of the seventh lens to the imaging plane, thereby reducing interference between the lens assembly and its individual lenses during focusing, facilitating the manufacturing process of the camera lens assembly.

[0060] In an exemplary embodiment, the camera lens assembly according to the present application may satisfy the condition: V4 ≤ Vn, where V4 is the Abbe number of the fourth lens element, Vn is the Abbe number of the nth lens element, and n is selected from 1, 2, 3, 5, 6, and 7. Satisfying V4 ≤ Vn allows for achromatic aberration to be achieved by properly allocating the Abbe number combinations among the lenses, thereby reducing chromatic aberration, improving the imaging quality of the lens assembly, and minimizing color fringing.

[0061] In an exemplary embodiment, the first lens may have positive focal length, and the second lens may have negative focal length. Any two adjacent lenses from the first lens to the seventh lens have an air gap on the optical axis, wherein the air gap between the first lens and the second lens on the optical axis is the smallest. The present application, by setting the first lens to have positive focal length and the second lens to have negative focal length, is conducive to offsetting the spherical aberrations generated by the second lens and the first lens, thereby improving the resolution of the lens group. At the same time, by setting the air gap between the first lens and the second lens on the optical axis to be the smallest, the first lens and the second lens can be made close to being glued together, thereby helping to reduce self-chromatic aberration, reduce tolerance sensitivity, balance the overall chromatic aberration of the lens group through the residual partial chromatic aberration, reduce the distance between the two lenses, and thus reduce the total length of the lens group.

[0062] In an exemplary embodiment, the camera lens assembly according to the present application may satisfy the following conditions: tan(Semi-FOV)>0.8, where Semi-FOV is half of the maximum field of view of the camera lens assembly. Satisfying tan(Semi-FOV)>0.8 enables the lens assembly to have characteristics such as a large field of view.

[0063] In an exemplary embodiment, the camera lens group according to the present application further includes an aperture provided between the object side and the first lens. Optionally, the camera lens group may further include a filter for correcting color deviation and / or a protective glass for protecting the photosensitive element located on the imaging surface. The present application proposes a camera lens group having the characteristics of miniaturization, large aperture, ultra-thinness and high imaging quality. The camera lens group according to the above embodiment of the present application may adopt multiple lenses, such as the seven lenses mentioned above. By reasonably allocating the optical power, surface shape, center thickness of each lens and the on-axis spacing between each lens, the incident light can be effectively converged, the total optical length of the imaging lens can be reduced and the machinability of the imaging lens can be improved, making the camera lens group more conducive to production and processing.

[0064] In an 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 surface of the first lens to the image side surface of the seventh lens is an aspherical mirror surface. The characteristic of an 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, with the advantages of improving distortion aberration and improving astigmatism aberration. After adopting an aspherical lens, the aberration that occurs during imaging can be eliminated as much as possible, thereby improving the imaging quality. Optionally, at least one of the object side surface and the image side surface of each lens in the first lens, the second lens, the third lens, the fourth lens, the fifth lens, the sixth lens and the seventh lens is an aspherical mirror surface. Optionally, the object side surface and the image side surface of each lens in the first lens, the second lens, the third lens, the fourth lens, the fifth lens, the sixth lens and the seventh lens are all aspherical mirror surfaces.

[0065] However, those skilled in the art will appreciate that the number of lenses comprising the camera lens assembly can be varied to achieve the various results and advantages described herein without departing from the claimed technical solutions. For example, while seven lenses are described in the embodiments, the camera lens assembly is not limited to including seven lenses. If desired, the camera lens assembly can also include other numbers of lenses.
