Description

[0002] With the rapid development of portable smart devices, the consumer market has higher and higher requirements for mobile phone functions. In addition to high pixels and large apertures, they also pursue ultra-thin mobile phones.

[0003] The mainstream mobile phone lenses on the market currently have two types: one is to meet the requirements of a large image plane, but the mobile phone module protrudes too high from the surface of the mobile phone, reducing the overall aesthetics of the mobile phone; the other is to meet the requirements of a large aperture, which can effectively improve the amount of light entering and enhance beautiful, clear, and high-quality images. It is impossible to meet the requirements of a large image plane and a large aperture at the same time.

[0004] The mainstream mobile phone lenses on the market cannot meet the requirements of high pixels, large aperture and large image area while achieving miniaturization, and the processability of the lens also needs to be optimized.

[0043] The camera lens according to the exemplary embodiment of the present application includes a lens barrel, a lens group and a support member group arranged in the lens barrel. The lens group includes, from the object side to the image side along the optical axis, a first lens with positive optical power; a second lens with negative optical power; a third lens with positive optical power; a fourth lens with negative optical power; a fifth lens with optical power; a sixth lens with positive optical power; and a seventh lens with negative optical power; the support member group includes: a sixth support member placed between the sixth lens and the seventh lens and in at least partial contact with the image side of the sixth lens.

[0044] In an exemplary embodiment, the supporting member group of the camera lens may include at least one of the first supporting member, the second supporting member, the third supporting member, the fourth supporting member, the fifth supporting member and the sixth supporting member. The first supporting member is placed between the first lens and the second lens and is in at least partial contact with the image side of the first lens. The second supporting member is placed between the second lens and the third lens and is in at least partial contact with the image side of the second lens. The third supporting member is placed between the third lens and the fourth lens and is in at least partial contact with the image side of the third lens. The fourth supporting member is placed between the fourth lens and the fifth lens and is in at least partial contact with the image side of the fourth lens. The fifth supporting member is placed between the fifth lens and the sixth lens and is in at least partial contact with the image side of the fifth lens. The sixth supporting member is placed between the sixth lens and the seventh lens and is in at least partial contact with the image side of the sixth lens. It should be understood that the present application does not specifically limit the number of supporting members, and any number of supporting members may be included between any two lenses, and the entire camera lens may also include any number of supporting members. The supporting member helps the camera lens intercept excess refractive and reflective light paths and reduce the generation of stray light and ghost images. Adding auxiliary supports between the supports and the lens barrel is helpful to improve problems such as poor assembly stability and low performance yield caused by large step differences between lenses.

[0045] In an exemplary embodiment, the camera lens according to the present application may satisfy: 0.7<L / ImgH<1.5, where L is the maximum height of the lens barrel along the optical axis direction, and ImgH is half the diagonal length of the effective pixel area on the imaging surface of the camera lens. Satisfying 0.7<L / ImgH<1.5 enables the lens to meet the characteristics of miniaturization and large image surface.

[0046] In an exemplary embodiment, the imaging lens according to the present application may satisfy: -0.5<f / R12<0, wherein f is the effective focal length of the imaging lens, and R12 is the radius of curvature of the image side surface of the sixth lens.

[0047] In an exemplary embodiment, the camera lens according to the present application may satisfy: 0.6<f6 / D6s≤1.1, wherein f6 is the effective focal length of the sixth lens, and D6s is the outer diameter of the object side surface of the sixth supporting member.

[0048] In an exemplary embodiment, a half of the diagonal length ImgH of the effective pixel area on the imaging plane of the imaging lens according to the present application satisfies 5.8 mm<ImgH<6.0 mm.

[0049] The camera lens according to the exemplary embodiment of the present application is a seven-piece wide-angle lens, comprising: a lens barrel, a lens group and a supporting member group placed in the lens barrel, wherein the lens group comprises, in order from the object side to the image side along the optical axis: a first lens with positive optical power; a second lens with negative optical power; a third lens with positive optical power; a fourth lens with negative optical power; a fifth lens with optical power; a sixth lens with positive optical power; and a seventh lens with negative optical power; the supporting member group comprises: a sixth supporting member placed between the sixth lens and the seventh lens and in at least partial contact with the image side surface of the sixth lens; the camera lens of the present application The head can satisfy 0.7<L / ImgH<1.5, -0.5<f / R12<0 and 0.6<f6 / D6s≤1.1, so that the camera lens has the characteristics of miniaturization and large image surface. By effectively controlling the effective focal length and surface shape of the sixth lens, the direction of light can be controlled, so that the step difference between the sixth lens and the seventh lens is smaller, the assembly stability of the system is higher, and the assembly processability of the entire lens is significantly improved; at the same time, by controlling the outer diameter of the image side surface of the sixth supporting member, the excess edge light after passing through the sixth lens can be effectively blocked, and the internal reflection stray light generated in the sixth lens is absorbed, thereby improving the stray light problem.

[0050] The following is combined with Table 1-1 to further illustrate the effect of the above technical solution of the present application on improving assembly stability. Table 1-1 shows an analysis table of the change (i.e., displacement) of the air gap T67 between the sixth lens and the seventh lens relative to the design value of the three camera lenses under simulated assembly conditions, ΔSp6 represents the sensitivity of the air gap between the sixth lens and the seventh lens extracted by the simulation software, and the units of the displacement and ΔSp6 in Table 1-1 are both millimeters (mm).

[0051]

[0052] Table 1-1

[0053] In Table 1-1, camera lens 1 satisfies L / ImgH=1.020, f / R12=-0.2 and f6 / D6s=1.016, camera lens 2 satisfies L / ImgH=0.614, f / R12=-0.72 and f6 / D6s=0.441, and camera lens 3 satisfies L / ImgH=1.7, f / R12=0.2 and f6 / D6s=1.3. The displacement and ΔSp6 of camera lens 1 are significantly smaller than those of camera lens 2 and camera lens 3, and its stability is better. That is to say, when the values ​​of L / ImgH, f / R12 and f6 / D6s are all within the scope of the present application, the change in the air gap between the sixth lens and the seventh lens after the lens assembly is small, and when the values ​​of L / ImgH, f / R12 and f6 / D6s are outside the scope of the present application, the change in the air gap between the sixth lens and the seventh lens after the lens assembly is large. Therefore, the present application satisfies the conditional formulas 0.7<L / ImgH<1.5, -0.5<f / R12<0 and 0.6<f6 / D6s≤1.1, so that the step difference between the sixth lens and the seventh lens is smaller, the assembly stability of the system is higher, and the imaging quality stability is higher.

[0054] In an exemplary embodiment, the camera lens according to the present application can satisfy: 7.5<f3 / d3m<10.5, where f3 is the effective focal length of the third lens, and d3m is the inner diameter of the image side surface of the third supporting member. When 7.5<f3 / d3m<10.5 is satisfied, controlling the effective focal length of the third lens can control the direction of light passing through the third lens and the effective diameter shape of the lens; controlling the inner diameter of the image side surface of the third supporting member can improve the internal ghost image of the third lens and the stray light of the mechanism part, thereby improving the imaging quality of the system.

[0055] In an exemplary embodiment, the camera lens according to the present application can satisfy: -15.5≤f4 / d4m<-11.0, where f4 is the effective focal length of the fourth lens, and d4m is the inner diameter of the image side surface of the fourth support member. If -15.5≤f4 / d4m<-11.0 is satisfied, the direction of light passing through the fourth lens and the effective diameter shape of the lens can be controlled by controlling the effective focal length of the fourth lens; and the inner diameter of the image side surface of the fourth support member can improve the internal ghost image of the fourth lens and the stray light of the mechanism part, so that the imaging quality of the system is better.

[0056] In an exemplary embodiment, the camera lens according to the present application may satisfy: 2.5<R10 / d5s<3.3, wherein R10 is the radius of curvature of the image side surface of the fifth lens, and d5s is the inner diameter of the object side surface of the fifth support member. Satisfying 2.5<R10 / d5s<3.3 and controlling the ratio of the radius of curvature of the image side surface of the fifth lens to the inner diameter of the object side surface of the fifth support member within a certain range is conducive to reducing the system tolerance sensitivity and improving the MTF yield of the system.

[0057] In an exemplary embodiment, the camera lens according to the present application may satisfy: 4.5<R6 / d3s<8.5, where R6 is the radius of curvature of the image side surface of the third lens, and d3s is the inner diameter of the object side surface of the third supporting member. Satisfying 4.5<R6 / d3s<8.5 and controlling the ratio of the radius of curvature of the image side surface of the third lens to the inner diameter of the object side surface of the third supporting member within a certain range is conducive to reducing the astigmatism and distortion of the system and improving the imaging quality of the system.

[0058] In an exemplary embodiment, the camera lens according to the present application may satisfy: 0.5<(EP56+CP6) / (T56+T67)<1.0, wherein EP56 is the distance from the image side of the fifth support member to the object side of the sixth support member along the optical axis, CP6 is the maximum thickness of the sixth support member along the optical axis, T56 is the air gap between the fifth lens and the sixth lens on the optical axis, and T67 is the air gap between the sixth lens and the seventh lens on the optical axis. Satisfying 0.5<(EP56+CP6) / (T56+T67)<1.0, controlling the gap between the fifth support member and the sixth support member, and the air gap between the sixth lens and the seventh lens can reduce the field curvature sensitivity of the sixth lens and the seventh lens, thereby improving the MTF yield; in addition, by controlling the above conditional expression, the outer diameter and shape of the sixth lens can be controlled, improving the release problem during the molding process of large-diameter lenses.

[0059] In an exemplary embodiment, the camera lens according to the present application can satisfy: 2.0<T12 / CP1+CT1 / EP01<5.5, wherein T12 is the air gap between the first lens and the second lens on the optical axis, CP1 is the maximum thickness of the first supporting member along the optical axis, CT1 is the center thickness of the first lens on the optical axis, and EP01 is the distance from the object side end face of the lens barrel to the object side face of the first supporting member along the optical axis. Satisfying 2.0<T12 / CP1+CT1 / EP01<5.5, by controlling EP01, the wall thickness of the front end supporting surface of the lens barrel can be taken into account to ensure assembly stability, while taking into account the edge thickness of the mechanism part of the first lens to meet the lens molding process; in addition, by controlling the above conditional formula, the molding of the first lens meets the process parameters such as thickness ratio, and the assembly stability of the first lens is improved; further, the requirements of relevant parameters such as optical performance RI and CRA can be met.

[0060] In an exemplary embodiment, the camera lens according to the present application can satisfy: 12<R3 / d1m<2.5, where R3 is the radius of curvature of the object side of the second lens, and d1m is the inner diameter of the image side of the first supporting member. Satisfying 2<R3 / d1m<2.5 and controlling the ratio of the radius of curvature of the image side of the second lens to the inner diameter of the image side of the first supporting member within a certain range is conducive to reducing the tolerance sensitivity of the second lens and improving the yield of the finished product. At the same time, the first supporting member can block excess light and reduce the risk of stray light in the optical system.

[0061] In an exemplary embodiment, the camera lens according to the present application may satisfy: 1.0<R4 / d2s<1.6, where R4 is the radius of curvature of the image side surface of the second lens, and d2s is the inner diameter of the object side surface of the second supporting member. Satisfying 1.0<R4 / d2s<1.6 and controlling the ratio of the radius of curvature of the image side surface of the second lens to the inner diameter of the object side surface of the second supporting member within a certain range can reduce the tolerance sensitivity of the second lens and improve the finished product yield.

[0062] In an exemplary embodiment, the camera lens according to the present application can satisfy: 2.0<(CT3+T34) / EP23≤2.7, wherein CT3 is the center thickness of the third lens on the optical axis, T34 is the air gap between the third lens and the fourth lens on the optical axis, and EP23 is the distance from the image side of the second support member to the object side of the third support member along the optical axis. Satisfying 2.0<(CT3+T34) / EP23≤2.7 is conducive to making the third lens meet lens molding parameters such as thickness ratio and diameter-to-thickness ratio. At the same time, a reasonable space gap between the third lens and the fourth lens can control the direction of light and eliminate excess light, making the performance parameters of the entire optical system better.

[0063] In an exemplary embodiment, the camera lens according to the present application may satisfy: 1.5<(CT4+T45) / EP34<2.0, wherein CT4 is the center thickness of the fourth lens on the optical axis, T45 is the air gap between the fourth lens and the fifth lens on the optical axis, and EP34 is the distance from the image side of the third support member to the object side of the fourth support member along the optical axis. Satisfying 1.5<(CT4+T45) / EP34<2.0 is conducive to making the fourth lens meet the thickness ratio requirements and ensure the molding process; by controlling this conditional expression, the outer diameter and shape of the fourth lens can be controlled, so that the outer diameter, center-to-thickness ratio, and thickness ratio of the entire lens are optimized, and the release problem during the lens molding process is improved. At the same time, a reasonable air gap between the fourth lens and the fifth lens makes the overall MTF performance of the optical system better.

[0064] In an exemplary embodiment, the camera lens according to the present application can satisfy: 1.4<EP45 / CT5<1.7, wherein EP45 is the distance from the image side of the fourth support member to the object side of the fifth support member along the optical axis, and CT5 is the center thickness of the fifth lens on the optical axis. By controlling EP45, the edge thickness of the fifth lens can be controlled, and when EP45 and CT5 satisfy 1.4<EP45 / CT5<1.7, the curvature of the fifth lens can be effectively reduced, the molding risk and the appearance risk can be reduced, and good performance can be maintained under high temperature, high humidity and thermal shock conditions, which can greatly improve the stability of the overall lens.

[0065] In an exemplary embodiment, the camera lens according to the present application can satisfy: 2.5<f12 / (D2m-d2m)<5.5, wherein f12 is the combined focal length of the first lens and the second lens, D2m is the outer diameter of the image side of the second support member, and d2m is the inner diameter of the image side of the second support member. (D2m-d2m) is equivalent to the outer diameter difference of the second lens. Controlling the outer diameter difference of the second lens can meet the requirements of assembly support and make the assembly more stable; satisfying 2.5<f12 / (D2m-d2m)<5.5 can reasonably limit the range of the optical path through the exit pupil of the optical system, eliminate light with poor edge quality, avoid the residual field of view non-imaging light from being reflected to the image plane inside the system, and improve the imaging quality of the lens.

[0066] In an exemplary embodiment, the camera lens according to the present application may satisfy: -7.5<f45 / D5m<-4.0, wherein f45 is the combined focal length of the fourth lens and the fifth lens, and D5m is the outer diameter of the image side surface of the fifth support member. When -7.5<f45 / D5m<-4.0 is satisfied, the direction of light from the fourth lens and the fifth lens can be controlled so that the light goes to a wider angle, meeting the requirement of a large image surface.

[0067] According to an exemplary embodiment of the present application, a camera lens includes: a lens barrel and a lens group and a supporting member group disposed in the lens barrel, wherein the lens group includes, in order from the object side to the image side along the optical axis: a first lens with positive optical power; a second lens with negative optical power; a third lens with positive optical power; a fourth lens with negative optical power; a fifth lens with optical power; a sixth lens with positive optical power; and a seventh lens with negative optical power; the supporting member group includes: a first supporting member disposed between the first lens and the second lens and at least partially in contact with the image side surface of the first lens; an air gap T12 between the first lens and the second lens on the optical axis, a maximum thickness CP1 of the first supporting member along the optical axis, a center thickness CT1 of the first lens on the optical axis, and a distance EP01 from the object side end surface of the lens barrel to the object side surface of the first supporting member along the optical axis satisfying: 2.0<T12 / CP1+CT1 / EP01<5.5. By controlling EP01, the wall thickness of the front end bearing surface of the lens barrel can be taken into account to ensure the assembly stability, while the edge thickness of the mechanism part of the first lens can be taken into account to meet the lens molding process; in addition, by controlling the above conditional formula, the molding of the first lens meets the process parameters such as thickness ratio, and the assembly stability of the first lens is improved; further, the requirements of related parameters such as optical performance RI and CRA are met.

[0068] 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 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 having 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, the object side and image side of all lenses from the first lens to the seventh lens are aspherical mirror surfaces.

[0069] In an exemplary embodiment, the camera lens may further include a filter for correcting color deviation and / or a protective glass for protecting a photosensitive element located on the imaging surface.

[0070] The camera lens according to the above-mentioned embodiment of the present application can adopt multiple lenses, such as the seven lenses mentioned above. By reasonably allocating the focal length, surface shape and arrangement of each supporting member of each lens, the span of each gear of the lens and the lens barrel is made more uniform, the ability of light convergence is enhanced, and the imaging quality of the ultra-wide-angle and large-image-surface camera lens is improved. However, it should be understood by those skilled in the art that the number of lenses constituting the camera lens can be changed without departing from the technical solution claimed for protection in the present application to obtain the various results and advantages described in this specification. For example, although seven lenses are described as an example in the embodiment, the camera lens is not limited to including seven lenses. If necessary, the camera lens may also include other numbers of lenses.

[0071] The following further describes a specific embodiment of the camera lens applicable to the above-mentioned embodiment with reference to the accompanying drawings.
