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 for recognizing 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 front two lenses is likely to generate ghost images or stray light in the subsequent lenses. At the same time, if the size design of the bearing members between adjacent two lenses is unreasonable, it will also seriously affect the imaging quality of the lens. For example, if the inner diameter of the bearing member is too large, the interception of non-imaging light is insufficient, resulting in ghost images and stray light interference on the imaging surface; if the inner diameter of the bearing member 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 member, 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.

[0048] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The following embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present application. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. For example, the lens group, lens barrel and supporting member in each embodiment of the present application can be combined arbitrarily, and are not limited to the lens group in one embodiment can only be combined with the lens barrel, supporting member, etc. of the embodiment.

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

[0050] The camera lens according to the exemplary embodiment of the present application includes a lens barrel and a lens group and a supporting member group arranged in the lens barrel. The lens group may include six lenses with optical power, namely a first lens, a second lens, a third lens, a fourth lens, a fifth lens and a sixth lens. The six lenses are arranged in sequence from the object side to the image side along the optical axis. Any two adjacent lenses from the first lens to the sixth lens may have a spacing distance between them.

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

[0052] 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 and the fifth supporting member. The first supporting member is placed on the image side of the first lens and is in at least partial contact with the image side of the first lens. The second supporting member is placed on the image side of the second lens and is in at least partial contact with the image side of the second lens. The third supporting member is placed on the image side of the third lens and is in at least partial contact with the image side of the third lens. The fourth supporting member is placed on the image side of the fourth lens and is in at least partial contact with the image side of the fourth 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. The support member also helps to increase the auxiliary support between the lens and the lens barrel, which is beneficial to improve the problems of poor assembly stability and low performance yield caused by the large step difference between the lenses.

[0054] like 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 imaging lens according to the present application can 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 semi-field of view angle of the imaging 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, it also ensures the miniaturization of the lens and the small size of the object-side end head. 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 semi-field of view angle Semi-FOV of the imaging lens according to the present application is greater than 45°, and exemplarily, Semi-FOV can be in the range of 45° to 55°.

[0059] In an exemplary embodiment, the imaging lens according to the present application can 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 support member, and d1m is the inner diameter of the image side surface of the first support member. Satisfying 3.6 mm < f2 / (d2s / d1m) < 5.0 mm, 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, 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 risk of ghost images. And setting the inner diameters of the first support member and the second support member within a reasonable range can 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 too large an inner diameter of the first support member, which causes 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 support member, and is beneficial to improving the imaging quality of the imaging 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 sequentially includes, 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 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 4.4 mm < L × tan(Semi-FOV) < 5.8 mm and 3.6 mm < f2 / (d2s / d1m) < 5.0 mm. 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 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, avoid 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 4.4 mm < L × tan(Semi-FOV) < 5.8 mm and 3.6 mm < f2 / (d2s / d1m) < 5.0 mm, has the characteristics of wide angle and small head, and at the same time 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 , Figure 2A and Figure 2B respectively show the ray diagram of the camera lens 1 when L × tan(Semi-FOV) = 5.7 mm and f2 / (d2s / d1m) = 4.0 mm and the spot diagram on the imaging surface, Figure 2C and Figure 2D respectively show the ray diagram of the camera lens 2 when L × tan(Semi-FOV) = 5.7 mm and f2 / (d2s / d1m) = 5.67 mm and the spot diagram on the imaging surface, Figure 2E , Figure 2G and Fig.2IThree light diagrams of the camera lens 3 are shown when L×tan(Semi-FOV)=5.7mm and f2 / (d2s / d1m)=2.0mm are satisfied. Figure 2F , Figure 2H and Figure 2J They are shown respectively Figure 2E , Figure 2G and Fig.2I The spot pattern of the light on the imaging surface.

[0062] More specifically, Figure 2A The figure shows a light diagram of ghost images generated by the ineffective light of the camera lens 1 after being reflected from the image side of the sixth lens. The f2 / (d2s / d1m)=4.0mm of the camera lens 1 is within the scope of the present application. The size design of d2s and d1m is reasonable. The first supporting member can block certain ineffective light, effectively reducing the ghost images generated by the ineffective light after being reflected from the image side of the sixth lens, and avoiding the problem of stray light generated by the light passing through the first lens hitting the ineffective diameter area of ​​the second lens. Therefore, Figure 2B The energy of the ghosts on the imaging plane of the middle camera lens 1 is relatively low, with a maximum energy of 7.17E-7, and the positions of the ghosts are relatively concentrated.

[0063] More specifically, Figure 2C The figure shows the light diagram of ghost images generated by the ineffective light of the camera lens 2 after being reflected from the image side of the sixth lens. The f2 / (d2s / d1m)=5.67mm of the camera lens 2 is not within the scope of the present application. The small d1m causes a part of the effective light to be blocked by the first supporting member, further resulting in a serious lack of the physical state reflected by the imaging. At the same time, the ghost images presented are relatively concentrated, the energy is increased, and the risk of imaging noise is increased. Therefore, Figure 2D Although the area of ​​the ghost image on the imaging surface of the middle camera lens 2 is small, the energy is increased, and the maximum energy is 2.15E-6, which seriously affects the imaging quality.

[0064] refer to Figure 2E to Figure 2J , f2 / (d2s / d1m)=2.0mm of the camera lens 3 is not within the scope of the present application, d1m is too large, and three types of light spots can be generated on the imaging surface of the camera lens 3. The first type of light spot is a ghost light spot generated by the reflection of ineffective light on the image side of the sixth lens, Figure 2E The ray diagram showing the ghost image produced by this part of ineffective light ( Figure 2E and Figure 2A same), Figure 2F The spot diagram of the ghost is shown in Figure 2F and Figure 2B The second type of light spot is the stray light spot generated when the light passing through the first lens hits the non-effective diameter area of ​​the second lens. Figure 2GThe ray diagram showing the stray light generated by this part of the light is shown. Figure 2H The spot diagram of the stray light is shown. The third spot is the stray light spot generated by the unreasonable matching of the first bearing member and the second bearing member, which causes the light passing through the second lens to be reflected at the second bearing member. Fig.2I The ray diagram showing the stray light generated by this part of the 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 can satisfy: 3.3 < |f3 / d3s| < 6.7, where f3 is the effective focal length of the third lens and d3s is the inner diameter of the object side of the third bearing member. The third lens can have a negative optical power and satisfy 3.3 < |f3 / d3s| < 6.7. By reasonably restricting the relationship between the effective focal length of the third lens and the inner diameter of the object side of the third bearing member, it helps to avoid the phenomenon of specular interference between the third bearing member and the image side of the third lens, and further avoid the situation where the transmittance and refractive index of the lens are affected due to the damage of the lens film layer caused by specular interference; at the same time, the inner diameter of the object side of the third bearing member satisfying the above range also helps to reduce the risk of insufficient interception of non-imaging light due to too large an inner diameter of the third bearing member or the risk of intercepting part of the imaging light due to too small an inner diameter of the third bearing member, and avoid the phenomena such as reduced imaging clarity, poor quality, and insufficient authenticity of restoring things in the lens.

[0066] In an exemplary embodiment, the camera lens according to the present application can satisfy: 1.65 < f1 / f2 < 5.2 and 0.95 < D2s / D1s < 1.7, where f1 is the effective focal length of the first lens, f2 is the effective focal length of the second lens, D2s is the outer diameter of the object side of the second bearing member, and D1s is the outer diameter of the object side of the first bearing member. By restricting the relationship between the effective focal lengths of the first lens and the second lens to satisfy 1.65 < f1 / f2 < 5.2, it helps to reduce the risk of defocus caused by abnormal transfer and承接 of light between different lenses and improve the authenticity and clarity of imaging. At the same time, on the premise of high-quality imaging, restricting the relationship between the outer diameters of the object sides of the first bearing member and the second bearing member to satisfy 0.95 < D2s / D1s < 1.7 helps to avoid the problem of too large a difference in the outer diameters of the first bearing member and the second bearing member and reduce the risk of abnormal assembly of the lens and the bearing member due to too large a difference in the outer diameters of adjacent lenses.

[0067] In an exemplary embodiment, the camera lens according to the present application can satisfy: 24.2mm -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 bearing 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 light is transmitted to the image plane, is also conducive 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 bearing member. By designing the position and inner diameter of the first bearing member, non-imaging light can be intercepted, the risk of ghosting can be reduced, and by controlling the light flux through the inner diameter of the object side of the first bearing member, it helps to improve the relative illumination 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 of the first bearing 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 of the first bearing 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, enabling the first lens to have a relatively small thickness ratio (i.e., the ratio of the edge thickness to the central thickness), and having 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 bearing member to the object side of the second bearing member, EP23 is the distance along the optical axis from the image side of the second bearing member to the object side of the third bearing 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 bearing member and the second bearing member, the second bearing member and the third bearing 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 in a "one" shape, effectively reducing the risks of ghosting and unclear imaging caused by damage to the lens surface due to 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.

[0070] In an exemplary embodiment, the camera lens according to the present application may satisfy: 0.5<(D3m-d3m) / DT41<1.6, wherein D3m is the outer diameter of the image side surface of the third support member, d3m is the inner diameter of the image side surface of the third support 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 take into account the relationship between the inner diameter and outer diameter of the third support member and the effective semi-aperture of the object side surface of the fourth lens during design, giving the third support member a relatively large annular width, so that the width of the surface where the lens contacts and supports the support member is sufficient, thereby improving assembly stability; at the same time, it also helps to improve the processability and assembly stability of the third support member on the premise that the inner diameter of the third support member can present a high-quality image on the image surface through the maximum luminous flux.

[0071] In an exemplary embodiment, the camera lens according to the present application may satisfy: 0.3<(D0s-d0s) / (DT61-DT12)<1.0, wherein D0s is the outer diameter of the object side end face of the lens barrel, d0s is the inner diameter of the object side end face of the lens barrel, DT61 is the effective semi-aperture of the object side face of the sixth lens, and DT12 is the effective semi-aperture of the image side face of the first lens. Satisfying 0.3<(D0s-d0s) / (DT61-DT12)<1.0 helps to highlight the overall "V"-shaped structure of the small head wide-angle lens by constraining the relationship between the inner diameter and the outer diameter of the object side end face of the lens barrel, the image side face of the first lens, and the effective semi-aperture of the object side face of the sixth lens, so that the wall thickness of the front and rear parts of the lens barrel is relatively uniform, reducing the risk of weld marks, shrinkage marks, etc. on the lens barrel, improving the reliability of the lens, and ensuring 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, wherein 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, 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 f45 is the combined focal length of the fourth lens and the fifth lens. Satisfying 0.15<(EP34+EP45) / f45<0.35, by constraining the relationship between the spacing distance of the third support member, the fourth support member, and the fifth support member in the optical axis direction and the combined focal length of the fourth lens and the fifth lens, helps the lens to have a larger field of view while weakening the contribution of the fourth lens and the fifth lens to chromatic aberration, so that the lens has a larger imaging angle and a high imaging resolution.

[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 to have good processability and sufficient assembly annular width by restricting 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 intercepts too much 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 in 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 restricting 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 having an overlong cantilever state when the third support member is in contact with the image side surface of the third lens for assembly, and maximally reduces the risk that the inner diameter side of the third support member close to the optical axis moves along the optical axis direction due to external environmental factors, thereby maximally avoiding the risk of poor stability of the relative illumination of the imaging and poor 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 (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 half field of view angle of the camera lens. Satisfying 65.0° < L / f × Semi-FOV < 73.4° helps the camera lens achieve the characteristics of a wide angle, and while obtaining a larger field of view, the image of the object being photographed can be better presented on the image plane, avoiding the situation where it is difficult to present a clear image in the finished product of the lens and module assembly due to the maximum height L of the lens barrel along the optical axis 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 subsequent 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 subsequent single lens and single support member, and enables the optimal assembly to obtain an MTF high-performance lens with the best performance.

[0079] 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. Among them, the lens group sequentially includes, 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 can satisfy: 1.65 < f1 / f2 < 5.2 and 0.95 < D2s / D1s < 1.7, where f1 is the effective focal length of the first lens, f2 is the effective focal length of the second lens, D2s is the outer diameter of the object side surface of the second support member, and D1s is the outer diameter of the object side surface of the first support member. By constraining the relationship between the effective focal lengths of the first lens and the second lens to satisfy 1.65 < f1 / f2 < 5.2, it helps to reduce the risk of defocus caused by abnormal transfer and承接 between different lenses, and improve the authenticity and clarity of imaging. At the same time, on the premise of high-quality imaging, constraining the relationship between the outer diameters of the object side surfaces of the first support member and the second support member to satisfy 0.95 < D2s / D1s < 1.7 helps to avoid the problem of too large a difference in the outer diameters of the first support member and the second support member, and reduce the risk of abnormal assembly of the lens and the support member due to too large a difference in the outer diameters of adjacent lenses.

[0080] The camera lens according to an exemplary embodiment of the present application includes: a lens barrel, and 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 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 to tend to be basically the same as the surface shape of the object side surface by restricting the relationship among 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 area 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 support assembly, the risk of the third support member being in an over-long cantilever state can be 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 can be minimized, thereby maximizing the avoidance of the risk of poor stability of the relative illuminance of imaging and worrying imaging quality.

[0081] 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 sixth lens is an aspherical mirror surface. The characteristics of an aspherical lens are 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 an aspherical lens, it is possible to eliminate the aberration that appears during imaging as much as possible, 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 mirror 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-mentioned embodiment of the present application can adopt multiple lenses, such as the six 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 camera lens is improved, so that the camera lens provided by the present application has at least one of the imaging advantages such as wide viewing angle, high resolution, high relative illumination, low chromatic aberration, and low ghosting, and each structural element has good processability. 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 in the present application to obtain the various results and advantages described in this specification. For example, although six lenses are described as an example in the embodiment, the camera lens is not limited to including six lenses. If necessary, the camera lens may also include other numbers of lenses.

[0084] The following further describes a specific embodiment of the camera lens applicable to the above-mentioned embodiment with reference to the accompanying drawings.

The first lens E1 has an object side surface S1 and an image side surface S2. The second lens E2 has an object side surface S3 and an image side surface S4. The third lens E3 has an object side surface S5 and an image side surface S6. The fourth lens E4 has an object side surface S7 and an image side surface S8. The fifth lens E5 has an object side surface S9 and an image side surface S10. The sixth lens E6 has an object side surface S11 and an image side surface S12.

[0088] The camera lens 1001 further includes a filter (not shown) for correcting color deviation, the filter having an object side surface S13 and an image side surface S14. The camera lens 1001 further includes a stop STO (not shown) disposed on the object side of the first lens.
