Neither can simultaneously satisfy both the requirements of a large image sensor and a large aperture.

[0042] The present application will now be described in detail with reference to the accompanying drawings and embodiments. Figure 1This diagram illustrates the structural layout and some parameters of a camera lens according to this application. Those skilled in the art will understand that some parameters commonly used in the art (e.g., the center thickness CT1 of the first lens on the optical axis) are not shown in the diagram. Figure 1 As shown in the figure, Figure 1 The following is merely an example illustrating some parameters of the lens barrel and support member of a camera lens according to this application, in order to better understand the invention. Figure 1 As shown, CP1 is the maximum thickness of the first support member along the optical axis, CP6 is the maximum thickness of the sixth support member along the optical axis, EP01 is the distance from the object-side end face of the lens barrel to the object-side surface of the first support member along the optical axis, EP23 is the distance from the image-side surface of the second support member to the object-side surface of the third support member along the optical axis, EP34 is the distance from the image-side surface of the third support member to the object-side surface of the fourth support member along the optical axis, EP45 is the distance from the image-side surface of the fourth support member to the object-side surface of the fifth support member along the optical axis, and EP56 is the distance from the image-side surface of the fifth support member to the object-side surface of the sixth support member. The distance along the optical axis, L represents the maximum height of the lens barrel along the optical axis, d2s is the inner diameter of the object side of the second support member, d3s is the inner diameter of the object side of the third support member, d5s is the inner diameter of the object side of the fifth support member, D6s is the outer diameter of the object side of the sixth support member, d1m is the inner diameter of the image side of the first support member, d2m is the inner diameter of the image side of the second support member, d4m is the inner diameter of the image side of the fourth support member, d3m is the inner diameter of the image side of the third support member, D2m is the outer diameter of the image side of the second support member, and D5m is the outer diameter of the image side of the fifth support member.

[0043] A camera lens according to an exemplary embodiment of this application includes a lens barrel and a lens assembly and a support assembly disposed within the lens barrel. The lens assembly includes, in sequence along the optical axis from the object side to the image side: a first lens having positive optical power; a second lens having negative optical power; a third lens having positive optical power; a fourth lens having negative optical power; a fifth lens having optical power; a sixth lens having positive optical power; and a seventh lens having negative optical power. The support assembly includes a sixth support member disposed between the sixth and seventh lenses and in at least partial contact with the image-side surface of the sixth lens.

[0044] In an exemplary embodiment, the camera lens mounting assembly may include at least one of a first mounting member, a second mounting member, a third mounting member, a fourth mounting member, a fifth mounting member, and a sixth mounting member. The first mounting member is positioned between a first lens and a second lens and at least partially contacts the image-side surface of the first lens. The second mounting member is positioned between a second lens and a third lens and at least partially contacts the image-side surface of the second lens. The third mounting member is positioned between a third lens and a fourth lens and at least partially contacts the image-side surface of the third lens. The fourth mounting member is positioned between a fourth lens and a fifth lens and at least partially contacts the image-side surface of the fourth lens. The fifth mounting member is positioned between a fifth lens and a sixth lens and at least partially contacts the image-side surface of the fifth lens. The sixth mounting member is positioned between a sixth lens and a seventh lens and at least partially contacts the image-side surface of the sixth lens. It should be understood that this application does not specifically limit the number of mounting members; any number of mounting members may be included between any two lenses, and the entire camera lens may also include any number of mounting members. The mounting members help the camera lens intercept excess reflected light paths, reducing stray light and ghosting. Adding auxiliary support between the support component and the lens barrel helps 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 this application satisfies the following condition: 0.7 < L / ImgH < 1.5, where L is the maximum height of the lens barrel along the optical axis, 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 a large image area.

[0046] In an exemplary embodiment, the camera lens according to this application can satisfy: -0.5 < f / R12 < 0, where f is the effective focal length of the camera 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 this application can satisfy: 0.6 < f6 / D6s ≤ 1.1, where f6 is the effective focal length of the sixth lens and D6s is the outer diameter of the object side of the sixth support member.

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

[0049] The camera lens according to an exemplary embodiment of this application is a seven-element wide-angle lens, comprising: a lens barrel and a lens group and a support group disposed within the lens barrel, wherein the lens group comprises, along the optical axis from the object side to the image side, a first lens having positive optical power; a second lens having negative optical power; a third lens having positive optical power; a fourth lens having negative optical power; a fifth lens having optical power; a sixth lens having positive optical power; and a seventh lens having negative optical power; the support group comprises: a sixth support member disposed between the sixth lens and the seventh lens and at least partially in contact with the image side surface of the sixth lens; the camera lens of this application The lens can meet the requirements of 0.7 < L / ImgH < 1.5, -0.5 < f / R12 < 0, and 0.6 < f6 / D6s ≤ 1.1, giving the camera lens the characteristics of miniaturization and a large image plane. By effectively controlling the effective focal length and surface shape of the sixth lens, the direction of light can be controlled, resulting in a smaller step difference between the sixth and seventh lenses, higher system assembly stability, and a significant improvement in the overall lens assembly processability. At the same time, by controlling the outer diameter of the image side of the sixth support component, excess edge light after passing through the sixth lens can be effectively blocked, while absorbing the internal reflection stray light generated within the sixth lens, thus improving the stray light problem.

[0050] The following, in conjunction with Table 1-1, further illustrates the effect of the above-mentioned technical solution of this application on improving assembly stability. Table 1-1 shows the analysis of the change (i.e., displacement) of the air gap T67 between the sixth and seventh lenses of the three camera lenses relative to the design value under simulated assembly conditions. ΔSp6 represents the sensitivity of the air gap between the sixth and seventh lenses extracted by the simulation software. The units of displacement and ΔSp6 in Table 1-1 are 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, indicating better stability. In other words, when the values ​​of L / ImgH, f / R12, and f6 / D6s are all within the range of this application, the change in air gap between the sixth and seventh lenses after lens assembly is small. Conversely, when the values ​​of L / ImgH, f / R12, and f6 / D6s are outside the range of this application, the change in air gap between the sixth and seventh lenses after lens assembly is large. Therefore, this application satisfies the conditions 0.7 < L / ImgH < 1.5, -0.5 < f / R12 < 0, and 0.6 < f6 / D6s ≤ 1.1, resulting in a smaller step difference between the sixth and seventh lenses, higher system assembly stability, and higher image quality stability.

[0054] In an exemplary embodiment, the camera lens according to this application satisfies: 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 support member. Satisfying 7.5 < f3 / d3m < 10.5 controls the effective focal length of the third lens, thereby controlling the direction of light rays 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 support member improves the reduction of ghosting images and stray light in the mechanism portion of the third lens, thus improving the system's imaging quality.

[0055] In an exemplary embodiment, the camera lens according to this application satisfies: -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. Satisfying -15.5 ≤ f4 / d4m < -11.0 controls the effective focal length of the fourth lens, thereby controlling the direction of light rays passing through the fourth lens and the effective diameter shape of the lens; controlling the inner diameter of the image-side surface of the fourth support member improves the reflection of ghost images in the fourth lens and reduces stray light in the mechanism, resulting in better image quality of the system.

[0056] In an exemplary embodiment, the camera lens according to this application satisfies the following condition: 2.5 < R10 / d5s < 3.3, where 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 beneficial for reducing system tolerance sensitivity and improving the system's MTF yield.

[0057] In an exemplary embodiment, the camera lens according to this application satisfies the following condition: 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 support 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 support member within a certain range, is beneficial for reducing astigmatism and distortion in the system and improving the imaging quality of the system.

[0058] In an exemplary embodiment, the camera lens according to this application satisfies: 0.5 < (EP56 + CP6) / (T56 + T67) < 1.0, where EP56 is the distance along the optical axis from the image side of the fifth support member to the object side of the sixth support member, CP6 is the maximum thickness of the sixth support member along the optical axis, T56 is the air gap between the fifth and sixth lenses on the optical axis, and T67 is the air gap between the sixth and seventh lenses on the optical axis. Satisfying 0.5 < (EP56 + CP6) / (T56 + T67) < 1.0, controlling the spacing between the fifth and sixth support members and the air gap between the sixth and seventh lenses can reduce the field curvature sensitivity of the sixth and seventh lenses, 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-aperture lenses.

[0059] In an exemplary embodiment, the camera lens according to this application satisfies: 2.0 < T12 / CP1 + CT1 / EP01 < 5.5, where 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 support 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 support member along the optical axis. Satisfying 2.0 < T12 / CP1 + CT1 / EP01 < 5.5, by controlling EP01, the wall thickness of the front support surface of the lens barrel can be considered to ensure assembly stability, while also considering the edge thickness of the mechanism portion of the first lens to meet the lens forming process requirements. Furthermore, by controlling the above conditional expression, the forming of the first lens satisfies process parameters such as thickness ratio, while also improving the assembly stability of the first lens. Further, it meets the requirements for optical performance parameters such as RI and CRA.

[0060] In an exemplary embodiment, the camera lens according to this application satisfies: 12 < R3 / d1m < 2.5, where R3 is the radius of curvature of the object-side surface of the second lens, and d1m is the inner diameter of the image-side surface of the first support member. Satisfying 2 < R3 / d1m < 2.5 controls the ratio of the radius of curvature of the image-side surface of the second lens to the inner diameter of the image-side surface of the first support member within a certain range, which is beneficial to reducing the tolerance sensitivity of the second lens and improving the yield of finished products. At the same time, the first support 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 this application satisfies the following condition: 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 support member. By 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 support member within a certain range, the tolerance sensitivity of the second lens can be reduced, and the yield rate of the finished product can be improved.

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

[0063] In an exemplary embodiment, the camera lens according to this application satisfies: 1.5 < (CT4 + T45) / EP34 < 2.0, where CT4 is the center thickness of the fourth lens on the optical axis, T45 is the air gap between the fourth and fifth lenses on the optical axis, and EP34 is the distance along the optical axis from the image side of the third support member to the object side of the fourth support member. Satisfying 1.5 < (CT4 + T45) / EP34 < 2.0 helps ensure that the fourth lens meets the thickness-to-thickness ratio requirement, guaranteeing the molding process. By controlling this conditional expression, the outer diameter and shape of the fourth lens can be controlled, resulting in better overall lens outer diameter, thickness-to-thickness ratio, and thickness-to-thickness ratio, improving issues such as release during lens molding. Simultaneously, a reasonable air gap between the fourth and fifth lenses leads to better overall MTF performance of the optical system.

[0064] In an exemplary embodiment, the camera lens according to this application satisfies: 1.4 < EP45 / CT5 < 1.7, where EP45 is the distance along the optical axis from the image-side surface of the fourth support member to the object-side surface of the fifth support member, and CT5 is the center thickness of the fifth lens along the optical axis. By controlling EP45, the edge thickness of the fifth lens can be controlled. Therefore, when EP45 and CT5 satisfy 1.4 < EP45 / CT5 < 1.7, the curvature of the fifth lens can be effectively reduced, reducing molding and appearance risks. It can also maintain good performance under high temperature, high humidity, and thermal shock conditions, significantly improving the overall stability of the lens.

[0065] In an exemplary embodiment, the camera lens according to this application satisfies the following condition: 2.5 < f12 / (D2m-d2m) < 5.5, where f12 is the combined focal length of the first lens and the second lens, D2m is the outer diameter of the image-side surface of the second support member, and d2m is the inner diameter of the image-side surface of the second support member. (D2m-d2m) is equivalent to the difference in the outer diameter of the second lens. Controlling the difference in the outer diameter of the second lens can meet the assembly support requirements, making the assembly more stable. Satisfying 2.5 < f12 / (D2m-d2m) < 5.5 can reasonably limit the optical path range through the exit pupil of the optical system, eliminate light rays with poor edge quality, and prevent non-imaging light rays in the remaining field of view from being reflected to the image plane inside the system, thereby improving the imaging quality of the lens.

[0066] In an exemplary embodiment, the camera lens according to this application satisfies: -7.5 < f45 / D5m < -4.0, where f45 is the combined focal length of the fourth and fifth lenses, and D5m is the outer diameter of the image-side surface of the fifth support member. Satisfying -7.5 < f45 / D5m < -4.0 allows control over the light path of the fourth and fifth lenses, resulting in a wider angle of light and meeting the requirement for a large image area.

[0067] A camera lens according to an exemplary embodiment of this application includes: a lens barrel and a lens group and a support group disposed within the lens barrel, wherein the lens group comprises, in sequence along the optical axis from the object side to the image side: a first lens having positive optical power; a second lens having negative optical power; a third lens having positive optical power; a fourth lens having negative optical power; a fifth lens having optical power; a sixth lens having positive optical power; and a seventh lens having negative optical power; the support group includes: a first support 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; the air gap T12 between the first lens and the second lens on the optical axis, the maximum thickness CP1 of the first support member along the optical axis, the center thickness CT1 of the first lens on the optical axis, and the distance EP01 from the object side end face of the lens barrel to the object side surface of the first support member along the optical axis satisfy: 2.0 < T12 / CP1 + CT1 / EP01 < 5.5. By controlling EP01, the wall thickness of the front bearing surface of the lens barrel can be taken into account to ensure assembly stability, while the edge thickness of the mechanism of the first lens can be taken into account to meet the lens forming process. In addition, by controlling the above-mentioned conditional formula, the forming of the first lens can meet the process parameters such as thickness ratio, and the assembly stability of the first lens can be improved. Furthermore, it can meet the relevant parameter requirements such as optical performance RI and CRA.

[0068] In embodiments of this application, at least one of the mirror surfaces of each lens is an aspherical mirror surface; that is, at least one mirror surface 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 its curvature changes continuously from the lens center to the lens periphery. Unlike a spherical lens, which has a constant curvature from the lens center to the lens periphery, an aspherical lens has better radius of curvature characteristics, offering advantages in improving distortion aberrations and astigmatism. By using an aspherical lens, aberrations occurring during imaging can be eliminated as much as possible, thereby improving image quality. Optionally, the object-side surface and image-side surface of all lenses from the first 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 the photosensitive element located on the imaging surface.

[0070] The camera lens according to the above embodiments of this application can employ multiple lenses, such as the seven lenses mentioned above. By rationally allocating the optical power, surface shape, and arrangement of the supporting components of each lens, the range of each lens-lens engagement position is made more uniform, enhancing the light-gathering ability and improving the imaging quality of the ultra-wide-angle, large-image-size camera lens. However, those skilled in the art should understand that the number of lenses constituting the camera lens can be changed without departing from the technical solutions claimed in this application to obtain the various results and advantages described in this specification. For example, although seven lenses are described as an example in the embodiments, 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 describes a specific embodiment of a camera lens applicable to the above-described embodiments with reference to the accompanying drawings. Specifically, referring to...

[0081] Where x is the distance vector from the vertex of the aspherical surface at a height h along the optical axis; c is the paraxial curvature of the aspherical surface, c = 1 / R (i.e., the paraxial curvature c is the reciprocal of the radius of curvature R in Table 1-2 above); k is the conic coefficient; Ai is the i-th order correction coefficient of the aspherical surface.
