Description

Technical Field

[0001] This application relates to the field of optical elements, and specifically, to a camera lens. Background Art

[0002] With the innovation of technology, fields such as machine intelligence and human-machine interaction systems have developed rapidly. However, there are still some deficiencies. One of them is that the authenticity and effectiveness of the images obtained by the camera lens in the machine system or the recognition of the surrounding environment are relatively poor, and the imaging quality of the camera lens severely limits the improvement of the overall performance of the machine system.

[0003] For a six-piece lens, when meeting the requirements of a large field of view angle and a small head, the light passing through the first two lenses in the front is likely to generate ghost images or stray light in the subsequent lenses. At the same time, if the size design of the bearing parts between adjacent lenses is unreasonable, it will also seriously affect the imaging quality of the lens. For example, if the inner diameter of the bearing part is too large, the interception of non-imaging light will be insufficient, resulting in ghost images and stray light interference on the imaging surface; if the inner diameter of the bearing part is too small, it will intercept some imaging light, resulting in phenomena such as reduced imaging clarity, poor quality, and insufficient authenticity of restoring things.

[0004] Therefore, reasonably setting the spatial arrangement and related parameters of the lens and the bearing parts, while reducing the risk of ghost images and stray light, improving the clarity of the lens and the authenticity of restoring things, is of great significance for the further development of the fields of machine intelligence and human-machine interaction systems.

[0049] The present application will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.

[0050] A camera lens according to an exemplary embodiment of the present application includes a lens barrel, and a lens group and a supporting member group disposed in the lens barrel. The lens group may include six lenses having optical power, namely a first lens, a second lens, a third lens, a fourth lens, a fifth lens, and a sixth lens. These six lenses are arranged in sequence along the optical axis from the object side to the image side. There may be a spacing distance between any two adjacent lenses among the first lens to the sixth lens.

[0051] In the exemplary embodiment, the first lens may have a positive optical power, the second lens may have a positive optical power, the third lens may have a negative optical power, the fourth lens may have a positive optical power, the fifth lens may have a negative optical power, and the sixth lens may have a negative optical power.

[0052] In an exemplary embodiment, the support member group of the camera lens may include at least one of a first support member, a second support member, a third support member, a fourth support member, and a fifth support member. The first support member is placed on the image side of the first lens and at least partially contacts the image side surface of the first lens. The second support member is placed on the image side of the second lens and at least partially contacts the image side surface of the second lens. The third support member is placed on the image side of the third lens and at least partially contacts the image side surface of the third lens. The fourth support member is placed on the image side of the fourth lens and at least partially contacts the image side surface of the fourth lens. The fifth support member is placed on the image side of the fifth lens and at least partially contacts the image side surface of the fifth lens. It should be understood that the present application does not specifically limit the number of support members. Any number of support members may be included between any two lenses, and the entire camera lens may also include any number of support members. The support members help the camera lens intercept redundant catadioptric light paths, reducing the generation of stray light and ghost images. The support members also help increase the auxiliary support between the lens and the lens barrel, which is beneficial to improving problems such as poor assembly stability and low performance yield caused by large step differences between lenses.

[0053] Figure 1A FIG. shows a structural layout diagram of a camera lens according to the present application and a schematic diagram of some parameters. As Figure 1A shown, a camera lens according to the present application may include a lens barrel P0 and a lens group and a support member group placed inside the lens barrel P0. The lens group includes, in order from the object side to the image side along the optical axis: a first lens, a second lens, a third lens, a fourth lens, a fifth lens, and a sixth lens. The support member group includes a first support member P1, a second support member P2, a third support member P3, a third auxiliary support member P3b, a fourth support member P4, and a fifth support member P5. The first support member P1 is placed on the image side of the first lens and at least partially contacts the image side surface of the first lens. The second support member P2 is placed on the image side of the second lens and at least partially contacts the image side surface of the second lens. The third support member P3 is placed on the image side of the third lens and at least partially contacts the image side surface of the third lens. The third auxiliary support member P3b is placed on the image side of the third support member P3 and at least partially contacts the image side surface of the third support member P3. The fourth support member P4 is placed on the image side of the fourth lens and at least partially contacts the image side surface of the fourth lens. The fifth support member P5 is placed on the image side of the fifth lens and at least partially contacts the image side surface of the fifth lens.

[0054] As Figure 1AAs shown in the figure, EP01 represents 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 direction, EP12 represents the distance from the image side face of the first supporting member to the object side face of the second supporting member along the optical axis direction, EP23 represents the distance from the image side face of the second supporting member to the object side face of the third supporting member along the optical axis direction, EP34 represents the distance from the image side face of the third supporting member to the object side face of the fourth supporting member along the optical axis direction, EP45 represents the distance from the image side face of the fourth supporting member to the object side face of the fifth supporting member along the optical axis direction, L represents the maximum height of the lens barrel along the optical axis direction, D0s represents the outer diameter of the object side end face of the lens barrel, and D2s represents The outer diameter of the object side surface of the second supporting member, d0s represents the inner diameter of the object side end surface of the lens barrel, D1s represents the outer diameter of the object side surface of the first supporting member, d2s represents the inner diameter of the object side surface of the second supporting member, d1s represents the inner diameter of the object side surface of the first supporting member, d1m represents the inner diameter of the image side surface of the first supporting member, d3s represents the inner diameter of the object side surface of the third supporting member, d3m represents the inner diameter of the image side surface of the third supporting member, D3m represents the outer diameter of the image side surface of the third supporting member, D3s represents the outer diameter of the object side surface of the third supporting member, d4s represents the inner diameter of the object side surface of the fourth supporting member, and D4s represents the outer diameter of the object side surface of the fourth supporting member.

[0055] Figure 1B A schematic diagram of parameters DT12, DT41, DT61, OD1 and OD6 is shown, wherein DT12 represents the effective semi-diameter of the image side of the first lens, DT41 represents the effective semi-diameter of the object side of the fourth lens, DT61 represents the effective semi-diameter of the object side of the sixth lens, OD1 represents the maximum outer diameter of the first lens in the direction perpendicular to the optical axis, and OD6 represents the maximum outer diameter of the sixth lens in the direction perpendicular to the optical axis.

[0056] It should be understood by those skilled in the art that some parameters of lenses commonly used in the art (such as the center thickness CT1 of the first lens on the optical axis) are not specified in the present invention. Figure 1A and Figure 1B It is shown in Figure 1A and Figure 1B Only some parameters of the lens barrel and the supporting member of a camera lens of the present application are exemplified to facilitate a better understanding of the present invention.

[0057] In an exemplary embodiment, the camera lens according to the present application may satisfy: 4.4 mm < L × tan(Semi-FOV) < 5.8 mm, where L is the maximum height of the lens barrel along the optical axis (i.e., the distance on the optical axis from the object side surface of the lens barrel to the image side surface of the lens barrel), and Semi-FOV is the maximum half field of view angle of the camera lens. By reasonably controlling the ratio of the maximum height of the lens barrel along the optical axis to the tangent of the field of view angle, while ensuring that the lens has a wide-angle feature, the miniaturization of the lens and the small size of the object-side end head are ensured. Reasonably designing the maximum height of the lens barrel along the optical axis also helps to ensure that the most protruding mirror surfaces among the object side surface of the first lens and the image side surface of the last lens are all located within the entire lens barrel, reducing the influence of external factors on the object side surface of the first lens and the image side surface of the last lens.

[0058] In an exemplary embodiment, the maximum half field of view angle Semi-FOV of the camera lens according to the present application is greater than 45°, and exemplarily, Semi-FOV may be in the range of 45° to 55°.

[0059] In an exemplary embodiment, the camera lens according to the present application may satisfy: 3.6 mm < f2 / (d2s / d1m) < 5.0 mm, where f2 is the effective focal length of the second lens, d2s is the inner diameter of the object side surface of the second bearing member, and d1m is the inner diameter of the image side surface of the first bearing member. Satisfying 3.6 mm < f2 / (d2s / d1m) < 5.0 mm, by reasonably setting the inner diameters of the first bearing member and the second bearing member, it is beneficial to block certain non-effective light rays, avoid the generation of ghost images due to the reflection of this part of non-effective light rays on the image side surface of the sixth lens, and is beneficial to reducing the ghost image risk. And setting the inner diameters of the first bearing member and the second bearing member within a reasonable range can avoid the problem of blocking effective light rays due to too small inner diameters of the bearing members, and can also avoid the problem of generating new stray light due to too large inner diameter of the first bearing member causing the light passing through the first lens to hit the non-effective diameter area of the second lens and the inner diameter end of the second bearing member, which is beneficial to improving the imaging quality of the camera lens.

[0060] The camera lens according to an exemplary embodiment of the present application includes: a lens barrel, a lens group, and a support member group disposed within the lens barrel. Among them, the lens group includes, in order from the object side to the image side along the optical axis: a first lens with a positive optical power, a second lens with a positive optical power, a third lens with a negative optical power, a fourth lens with a positive optical power, a fifth lens with a negative optical power, and a sixth lens with a negative optical power; the support member group includes: a first support member disposed on the image side of the first lens and at least partially in contact with the image side surface of the first lens, and a second support member disposed on the image side of the second lens and at least partially in contact with the image side surface of the second lens; the camera lens satisfies 4.4mm < L×tan(Semi - FOV) < 5.8mm and 3.6mm < f2 / (d2s / d1m) < 5.0mm. By reasonably controlling the ratio of the maximum height of the lens barrel along the optical axis direction to the tangent of the field of view angle, while ensuring that the lens has a wide - angle feature, it also has the characteristic of a smaller object - side end head. Reasonably designing the maximum height of the lens barrel along the optical axis direction also helps to ensure that the most protruding mirror surfaces among the object side surface of the first lens and the image side surface of the last lens are both located within the entire lens barrel, reducing the influence of external factors on the object side surface of the first lens and the image side surface of the last lens; at the same time, by reasonably setting the inner diameters of the first support member and the second support member, it is beneficial to block certain non - effective light rays, avoiding the generation of ghost images after the reflection of this part of non - effective light rays on the image side surface of the sixth lens, which is beneficial to reducing the risk of ghost images, and can also avoid the problem of blocking effective light rays due to too small an inner diameter of the support member, and can also avoid the problem of generating new stray light due to the light hitting the non - effective diameter area of the second lens and the inner diameter end of the second support member due to too large an inner diameter of the first support member, which is beneficial to improving the imaging quality of the camera lens.

[0061] The camera lens of the present application satisfies 4.4mm < L×tan(Semi - FOV) < 5.8mm and 3.6mm < f2 / (d2s / d1m) < 5.0mm, has the characteristics of wide - angle and small head, and also has the beneficial effects of reducing stray light and ghost images. The following further illustrates the role of the technical solution of the present application in reducing the risk of stray light or ghost images and improving the imaging quality in combination with FIG. 2A to FIG. 2J , further explaining the role of the technical solution of the present application in reducing the risk of stray light or ghost images and improving the imaging quality. Figure 2A and Figure 2B respectively show the ray diagram and the spot diagram on the imaging surface of the camera lens 1 when L×tan(Semi - FOV) = 5.7mm and f2 / (d2s / d1m) = 4.0mm, Figure 2C and Figure 2D respectively show the ray diagram and the spot diagram on the imaging surface of the camera lens 2 when L×tan(Semi - FOV) = 5.7mm and f2 / (d2s / d1m) = 5.67mm, Figure 2E , Figure 2G and Fig.2IShows three ray diagrams of the camera lens 3 when L×tan(Semi - FOV) = 5.7mm and f2 / (d2s / d1m) = 2.0mm, Figure 2F 、 Figure 2H and Figure 2J respectively show Figure 2E 、 Figure 2G and Fig.2I the spot diagrams of the rays in

[0062] on the imaging surface. Figure 2A More specifically, Figure 2B shows a ray diagram of ghosting generated by the reflection of non - effective rays of the camera lens 1 on the image side of the sixth lens. The f2 / (d2s / d1m) of the camera lens 1 is 4.0mm within the scope of this application, and the dimensions of d2s and d1m are reasonably designed. The first bearing member can block a certain amount of non - effective rays, effectively reducing the ghosting generated by the reflection of non - effective rays on the image side of the sixth lens, and avoiding the problem of stray light generated when the rays passing through the first lens hit the non - effective diameter area of the second lens. Therefore,

[0063] the energy of the ghosting on the imaging surface of the camera lens 1 in Figure 2C is relatively low, with a maximum energy of 7.17E - 7, and the position of the ghosting is relatively concentrated. Figure 2D More specifically,

[0064] shows a ray diagram of ghosting generated by the reflection of non - effective rays of the camera lens 2 on the image side of the sixth lens. The f2 / (d2s / d1m) of the camera lens 2 is 5.67mm not within the scope of this application, and d1m is on the small side, resulting in part of the effective rays being blocked by the first bearing member, further causing a serious lack of the physical state reflected in the imaging. At the same time, the presented ghosting is relatively concentrated and the energy increases, increasing the risk of imaging noise. Therefore, Figure 2E to Figure 2J in Figure 2E the area of the ghosting on the imaging surface of the camera lens 2 is small, but the energy increases, with a maximum energy of 2.15E - 6, seriously affecting the imaging quality. Figure 2E is the same as Figure 2A ), Figure 2F shows the spot diagram of this ghosting ( Figure 2F is the same as Figure 2B ), and the maximum energy of its ghosting is 7.17E - 7. The second type of spot is a stray light spot generated when the rays passing through the first lens hit the non - effective diameter area of the second lens. Figure 2GThe light diagram showing this part of light generating the stray light is shown. Figure 2H The third type of light spot is a stray light spot caused by the unreasonable matching of the first supporting member and the second supporting member, which causes the light passing through the second lens to be reflected at the second supporting member. Fig.2I The light diagram showing this part of light producing the stray light is shown. Figure 2J The spot diagram of the stray light is shown.

[0065] In an exemplary embodiment, the camera lens according to the present application may satisfy: 3.3<|f3 / d3s|<6.7, wherein f3 is the effective focal length of the third lens, and d3s is the inner diameter of the object side of the third support member. The third lens may have a negative optical power and satisfy 3.3<|f3 / d3s|<6.7. By reasonably constraining the relationship between the effective focal length of the third lens and the inner diameter of the object side of the third support member, it is helpful to avoid the phenomenon of mirror interference between the third support member and the image side of the third lens, thereby avoiding the situation where the transmittance and refractive index of the lens are affected by the damage to the mirror film layer caused by the mirror interference; at the same time, the inner diameter of the object side of the third support member satisfies the above range, which also helps to reduce the risk of insufficient interception of non-imaging light due to the excessively large inner diameter of the third support member or the risk of intercepting part of the imaging light due to the excessively small inner diameter of the third support member, thereby avoiding the occurrence of phenomena such as reduced imaging clarity, poor quality, and insufficient restoration of the authenticity of objects.

[0066] In an exemplary embodiment, the camera lens according to the present application may satisfy: 1.65 <f1 / f2<5.2以及0.95<D2s / D1s<1.7,其中,f1为第一镜片的有效焦距,f2为第二镜片的有效焦距,D2s为第二承靠件的物侧面的外径,D1s为第一承靠件的物侧面的外径。通过约束第一镜片和第二镜片的有效焦距的关系满足1.65<f1 / f2<5.2,有助于降低光线在不同镜片之间传递承接异常而导致离焦产生的风险,提高成像的真实度和清晰度。同时,基于高质量成像的前提下,约束第一承靠件和第二承靠元件的物侧面的外径之间的关系满足0.95<D2s / D1s<1.7,有助于规避第一承靠件和第二承靠元件的外径差值过大的问题,降低因相邻镜片外径差异过大而导致镜片与承靠件组装异常的风险。

[0067] In an exemplary embodiment, the camera lens according to the present application may meet the following requirements: 24.2 mm -1 <f1 / T12 / d1s<75.5mm -1, where f1 is the effective focal length of the first lens, T12 is the distance on the optical axis from the image side of the first lens to the object side of the second lens, and d1s is the inner diameter of the object side of the first supporting member. It satisfies 24.2 mm -1 <24.2 mm < f1 / T12 / d1s < 75.5 mm -1 , which helps to present a high-resolution image when the light is transmitted to the image plane, is also beneficial to the structural arrangement and processing of the non-effective diameter area of the lens, and at the same time gives enough placement space for the first supporting member. By designing the position and inner diameter of the first supporting member, non-imaging light can be intercepted, the risk of ghosting phenomenon can be reduced, and at the same time, by controlling the light flux through the inner diameter of the object side of the first supporting member, it helps to improve the relative illuminance of the camera lens.

[0068] In an exemplary embodiment, the camera lens according to the present application can satisfy: 2.1 < EP01 / CT1 < 2.6, where EP01 is the distance along the optical axis from the object side end face of the lens barrel to the object side face of the first supporting member, and CT1 is the central thickness of the first lens on the optical axis. By restricting the distance EP01 along the optical axis from the object side end face of the lens barrel to the object side face of the first supporting member, the edge thickness of the first lens is indirectly restricted. Therefore, satisfying 2.1 < EP01 / CT1 < 2.6 helps to control the central thickness and edge thickness of the first lens, so that the first lens has a relatively small thickness ratio (i.e., the ratio of the edge thickness to the central thickness), and has good processability.

[0069] In an exemplary embodiment, the camera lens according to the present application can satisfy: 1.4 < R4 / R5 < 2.6 and 2.8 < (EP12 + EP23) / T23 < 4.5, where R4 is the radius of curvature of the image side of the second lens, R5 is the radius of curvature of the object side of the third lens, EP12 is the distance along the optical axis from the image side of the first supporting member to the object side of the second supporting member, EP23 is the distance along the optical axis from the image side of the second supporting member to the object side of the third supporting member, and T23 is the distance on the optical axis from the image side of the second lens to the object side of the third lens. Satisfying 1.4 < R4 / R5 < 2.6 and 2.8 < (EP12 + EP23) / T23 < 4.5, by restricting the relationship between the radii of curvature of the image sides of the second lens and the third lens, the distances along the optical axis between the first supporting member and the second supporting member, the second supporting member and the third supporting member, and the air gap between the second lens and the third lens on the optical axis, it helps the surface shapes of the image sides of the second lens and the third lens to tend to be "one" shape, effectively reducing the risk of ghosting and unclear imaging caused by the too-close distance between the image side of the second lens and the object side of the third lens, and the too-close distance between the image side of the third lens and the object side of the fourth lens, which may cause mirror surface damage.

[0070] In an exemplary embodiment, the camera lens according to the present application may satisfy: 0.5 < (D3m - d3m) / DT41 < 1.6, where D3m is the outer diameter of the image side surface of the third supporting member, d3m is the inner diameter of the image side surface of the third supporting member, and DT41 is the effective semi-aperture of the object side surface of the fourth lens. Satisfying 0.5 < (D3m - d3m) / DT41 < 1.6 helps to consider the relationship between the inner diameter and outer diameter of the third supporting member and the effective semi-aperture of the object side surface of the fourth lens during design, gives a relatively large annular width to the third supporting member, makes the width of the surface where the lens contacts and supports the supporting member sufficient, and improves the assembly stability; at the same time, it also helps to improve the processability and assembly stability of the third supporting member on the premise that the inner diameter of the third supporting member can pass the maximum light flux to present a high-quality image on the image plane.

[0071] In an exemplary embodiment, the camera lens according to the present application may satisfy: 0.3 < (D0s - d0s) / (DT61 - DT12) < 1.0, where D0s is the outer diameter of the object side end surface of the lens barrel, d0s is the inner diameter of the object side end surface of the lens barrel, DT61 is the effective semi-aperture of the object side surface of the sixth lens, and DT12 is the effective semi-aperture of the image side surface of the first lens. Satisfying 0.3 < (D0s - d0s) / (DT61 - DT12) < 1.0 helps to highlight that the overall structure of the small-head wide-angle lens is a "V" shape by restricting the relationship between the inner diameter and outer diameter of the object side end surface of the lens barrel and the effective semi-apertures of the image side surface of the first lens and the object side surface of the sixth lens, makes the wall thickness of the front and rear parts of the lens barrel relatively uniform, reduces the risks of weld marks, sink marks, etc. on the lens barrel, improves the reliability of the lens, and ensures that the lens imaging has the characteristics of high stability, high quality, and low chromatic aberration.

[0072] In an exemplary embodiment, the camera lens according to the present application may satisfy: 0.15 < (EP34 + EP45) / f45 < 0.35, where EP34 is the distance along the optical axis from the image side surface of the third supporting member to the object side surface of the fourth supporting member, EP45 is the distance along the optical axis from the image side surface of the fourth supporting member to the object side surface of the fifth supporting member, and f45 is the combined focal length of the fourth lens and the fifth lens. Satisfying 0.15 < (EP34 + EP45) / f45 < 0.35 helps to weaken the contribution of the fourth lens and the fifth lens to chromatic aberration while the lens has a relatively large field of view, so that the lens has a relatively large imaging angle of view and high imaging resolution by restricting the relationship between the interval distances of the third supporting member, the fourth supporting member, and the fifth supporting member along the optical axis and the combined focal length of the fourth lens and the fifth lens.

[0073] In an exemplary embodiment, the camera lens according to the present application may satisfy: 0.7 < f4 / (D4s - d4s) < 1.9, where f4 is the effective focal length of the fourth lens, D4s is the outer diameter of the object side surface of the fourth support member, and d4s is the inner diameter of the object side surface of the fourth support member. Satisfying 0.7 < f4 / (D4s - d4s) < 1.9 helps the fourth support member have good processability and sufficient assembly annular width by constraining the relationship between the effective focal length of the fourth lens, the inner diameter and the outer diameter of the object side surface of the fourth support member. At the same time, it also helps to reduce the risk that the fourth support member excessively intercepts the imaging light passing through the edge of the fourth lens, resulting in the loss of light of the imaging object transmitted to the rear optical system, and improves the imaging quality of the camera lens and the ability to restore the authenticity of the object.

[0074] In an exemplary embodiment, the camera lens according to the present application may satisfy: 0.6 mm < D2s / d2s × EP23 < 1.2 mm, where D2s is the outer diameter of the object side surface of the second support member, d2s is the inner diameter of the object side surface of the second support member, and EP23 is the distance along the optical axis from the image side surface of the second support member to the object side surface of the third support member. Satisfying 0.6 mm < D2s / d2s × EP23 < 1.2 mm helps the structural design of the non-effective diameter region of the second lens, gives a reasonable design space to the non-effective diameter region of the second lens, improves the overall uniformity of the second lens, is beneficial to the processing and forming of the second lens, and is also beneficial to the second lens having a good and stable lens surface shape under the demolding process, effectively reducing the fluctuation of the effective focal length of the entire optical system, making the imaging clearer and restoring more comprehensive information of the object.

[0075] In an exemplary embodiment, the camera lens according to the present application may satisfy: 3.0 < f3 / R6 × (D3s / d3s) < 7.4, where f3 is the effective focal length of the third lens, R6 is the radius of curvature of the image side surface of the third lens, D3s is the outer diameter of the object side surface of the third support member, and d3s is the inner diameter of the object side surface of the third support member. Satisfying 3.0 < f3 / R6 × (D3s / d3s) < 7.4 helps the surface shape of the image side surface of the third lens to tend to be basically the same as the surface shape of the object side surface by constraining the relationship between the effective focal length of the third lens, the radius of curvature of the image side surface, the outer diameter and the inner diameter of the object side surface of the third support member, which is beneficial to the structural arrangement of the non-effective diameter region of the third lens; at the same time, the inner diameter of the third support member is reasonably designed to avoid the third support member being in an overlong cantilever state when the third support member is in contact with the image side surface of the third lens for support and assembly, and maximally reduces the risk of the inner diameter side of the third support member close to the optical axis moving along the optical axis due to external environmental factors, thereby maximally avoiding the risk of poor stability of the relative illumination of the imaging and worrying imaging quality.

[0076] In an exemplary embodiment, the camera lens according to the present application may satisfy: 65.0° < L / f × Semi-FOV < 73.4°, where L is the maximum height of the lens barrel along the optical axis direction (i.e., the distance on the optical axis from the object side of the lens barrel to the image side of the lens barrel), f is the effective focal length of the camera lens, and Semi-FOV is the maximum semi-field angle of the camera lens. Satisfying 65.0° < L / f × Semi-FOV < 73.4° helps the camera lens to achieve the characteristics of a wide angle, and while obtaining a larger field of view, the image of the photographed object can be better presented on the image plane, avoiding the situation where it is difficult to present a clear image for the finished product of the lens and the module assembly due to the maximum height L of the lens barrel along the optical axis direction being too large or too small.

[0077] In an exemplary embodiment, the camera lens according to the present application may satisfy: 4.1 < OD1 / DT11 < 5.3, where OD1 is the maximum outer diameter of the first lens in the direction perpendicular to the optical axis, and DT11 is the effective semi-aperture of the object side of the first lens. By restricting the relationship between the effective semi-aperture of the object side of the first lens and the maximum outer diameter of the first lens, the outer diameter of the first lens is potentially restricted, which is beneficial to the design of the effective apertures of the following five lenses, making the arrangement of the six lenses of the camera lens have a gradient, which is beneficial to the "V" shape design of the lens barrel, and enabling the lens and the support member to be assembled in a single direction.

[0078] In an exemplary embodiment, the camera lens according to the present application may satisfy: 1.5 ≤ OD6 / OD1 < 1.8, where OD6 is the maximum outer diameter of the sixth lens in the direction perpendicular to the optical axis, and OD1 is the maximum outer diameter of the first lens in the direction perpendicular to the optical axis. By restricting the relationship between the maximum outer diameters of the first lens and the sixth lens, it helps the outer diameters of the first lens and the second lens to form a stepped arrangement, which is beneficial to the assembly and adjustment combination of the following single lens and single support member, and realizes the optimized assembly to obtain the MTF high-performance lens with the best performance.

[0079] According to an exemplary embodiment of the present application, a camera lens comprises: a lens barrel, and a lens group and a supporting member group disposed 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 focal length, a second lens with positive focal length, a third lens with negative focal length, a fourth lens with positive focal length, a fifth lens with negative focal length, and a sixth lens with negative focal length; the supporting member group comprises: a first supporting member disposed on the image side of the first lens and in at least partial contact with the image side surface of the first lens, and a second supporting member disposed on the image side of the second lens and in at least partial contact with the image side surface of the second lens, and the camera lens can meet the following requirements: 1.65 <f1 / f2<5.2以及0.95<D2s / D1s<1.7,其中,f1为第一镜片的有效焦距,f2为第二镜片的有效焦距,D2s为第二承靠件的物侧面的外径,D1s为第一承靠件的物侧面的外径。通过约束第一镜片和第二镜片的有效焦距的关系满足1.65<f1 / f2<5.2,有助于降低光线在不同镜片之间传递承接异常而导致离焦产生的风险,提高成像的真实度和清晰度。同时,基于高质量成像的前提下,约束第一承靠件和第二承靠元件的物侧面的外径之间的关系满足0.95<D2s / D1s<1.7,有助于规避第一承靠件和第二承靠元件的外径差值过大的问题,降低因相邻镜片外径差异过大而导致镜片与承靠件组装异常的风险。

[0080] A camera lens according to an exemplary embodiment of the present application includes: a lens barrel, a lens group, and a support member group disposed within the lens barrel. The lens group includes, in order from the object side to the image side along the optical axis: a first lens with a positive focal power, a second lens with a positive focal power, a third lens with a negative focal power, a fourth lens with a positive focal power, a fifth lens with a negative focal power, and a sixth lens with a negative focal power. The support member group includes a third support member disposed on the image side of the third lens and at least partially in contact with the image side surface of the third lens. The camera lens can satisfy: 3.0 < f3 / R6×(D3s / d3s) < 7.4, where f3 is the effective focal length of the third lens, R6 is the radius of curvature of the image side surface of the third lens, D3s is the outer diameter of the object side surface of the third support member, and d3s is the inner diameter of the object side surface of the third support member. Satisfying 3.0 < f3 / R6×(D3s / d3s) < 7.4 helps the surface shape of the image side surface of the third lens and the surface shape of the object side surface to tend to be substantially the same by constraining the relationship between the effective focal length of the third lens, the radius of curvature of the image side surface, the outer diameter of the object side surface of the third support member, and the inner diameter, which is beneficial to the structural arrangement in the non-effective diameter region of the third lens. At the same time, by reasonably designing the inner diameter of the third support member, when the third support member is in contact with the image side surface of the third lens for supporting and assembling, the risk of the third support member being in an over-long cantilever state is avoided, and the risk of the inner diameter side of the third support member close to the optical axis moving along the optical axis direction caused by external environmental factors is minimized, thereby maximizing the avoidance of the risk of poor stability of the relative illuminance of imaging and poor imaging quality.

[0081] In an embodiment of the present application, at least one of the lens surfaces of each lens is an aspherical lens surface, that is, at least one of the lens surfaces from the object side surface of the first lens to the image side surface of the sixth lens is an aspherical lens 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. Different from a spherical lens with a constant curvature from the center of the lens to the periphery of the lens, an aspherical lens has better radius of curvature characteristics and has the advantages of improving distortion aberration and astigmatism aberration. After using aspherical lenses, it is possible to eliminate as much aberration as possible during imaging, thereby improving the imaging quality. Optionally, the object side surfaces and image side surfaces of all the lenses from the first lens to the sixth lens are aspherical lens surfaces.

[0082] In an exemplary embodiment, the above 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.

[0083] The camera lens according to the above embodiments of the present application may employ multiple lenses, such as the six lenses described above. By reasonably allocating the optical power, surface shape of each lens, and the arrangement of each supporting member, etc., the span of each gear in the cooperation between the lens and the lens barrel is relatively uniform, enhancing the ability of light convergence, improving the imaging quality of the camera lens, enabling the camera lens provided by the present application to have at least one of the imaging advantages such as large viewing angle, high resolution, high relative illumination, low chromatic aberration, and low ghosting, and each structural element having good processability. 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 may 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 embodiments, the camera lens is not limited to including six lenses. If necessary, the camera lens may also include other numbers of lenses.

[0084] The following further describes specific embodiments of the camera lens applicable to the above embodiments with reference to the accompanying drawings. Specifically, refer to FIG. 3A to FIG. 4D Describe the camera lens 1001 of Embodiment 1 and the camera lens 1002 of Embodiment 2 of the present application; refer to 5A to 6D Describe the camera lens 2001 of Embodiment 3 and the camera lens 2002 of Embodiment 4 of the present application; refer to 7A to 8D Describe the camera lens 3001 of Embodiment 5 and the camera lens 3002 of Embodiment 6 of the present application; refer to 9A to 10D Describe the camera lens 4001 of Embodiment 7 and the camera lens 4002 of Embodiment 8 of the present application.
