Description

Technical Field

[0001] The present application relates to the field of optical elements, and in particular, to a camera lens. Background Art

[0002] As people's quality of life improves, the demand for various portable communication devices is also increasing, and people's requirements for lens functionality and image quality are becoming increasingly higher. Lenses for small, handheld portable video communication devices must not only be compact enough to fit the device's space, but also meet the requirements of shock resistance and overcoming the high levels of stray light interference in outdoor environments. Six-element lenses, due to their relatively small number of elements, are a popular choice for portable video communication devices.

[0003] In a six-element wide-angle lens, the sixth lens element is typically the largest in diameter. Light passing through the fifth lens element is prone to generating internal stray light within the sixth lens element. Furthermore, the surface of the sixth lens element is also prone to reflecting light, generating stray light. If the lenses and support components are not properly matched, a large amount of stray light will directly enter the imaging surface, degrading the image quality of the camera lens. Therefore, controlling the spatial arrangement and optical parameters of the six-element lens elements and support components to reduce stray light interference and improve image quality is an urgent problem to be solved.

[0020] In a second aspect of the present application, there is provided a camera lens, which includes a lens barrel, a lens group, and a support member group disposed within the lens barrel. The lens group sequentially includes, from the object side to the image side along the optical axis: a first lens with a negative focal power, both its object side and image side being concave; a second lens with a positive focal power; a third lens with a positive focal power, both its object side and image side being convex; a fourth lens with a negative focal power, its image side being concave; a fifth lens with a positive focal power, both its object side and image side being convex; and a sixth lens with a negative focal power, its object side being convex and its image side being concave.

[0021] The present application provides a six-piece wide-angle camera lens. By reasonably distributing the positive and negative focal powers and surface types of each lens, the wide-angle characteristics of the lens are ensured. Due to the limitations of the overall shape and material of the fifth lens, the fifth lens has the largest central thickness and satisfies -4.8 < R10 / EP45 × N5 < -2.55. At the same time, the sixth lens is the lens with the largest diameter. Therefore, it is easy for light to generate internal reflection stray light within the sixth lens after passing through the fifth lens.

[0042] Figure 1AThe difference between the inner / outer diameters of the object side and image side of the supporting member shown is not very obvious, but those skilled in the art should understand that the inner / outer diameters of the object side or image side of the supporting member mentioned in this article refer to the inner / outer diameters measured at the position of the supporting member closest to the object side or image side.

[0043] A camera lens according to an exemplary embodiment of the present application includes a lens barrel, a lens assembly, and a support member assembly disposed within the lens barrel. The lens assembly 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. The six lenses are arranged in sequence along the optical axis from the object side to the image side. Any two adjacent lenses among the first to sixth lenses may be spaced apart by a distance.

[0044] In example embodiments, the first lens may have negative power, the second lens may have positive power, the third lens may have positive power, the fourth lens may have negative power, the fifth lens may have positive power, and the sixth lens may have negative power.

[0045] In an exemplary embodiment, the bearing member group may include a fourth bearing member positioned on the image side of the fourth lens and in at least partial contact with the image side surface of the fourth lens, and a fifth bearing member positioned on the image side of the fifth lens and in at least partial contact with the image side surface of the fifth lens.

[0046] In an exemplary embodiment, the support member assembly 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 positioned on the image side of the first lens and is in at least partial contact with the image side surface of the first lens. The second support member is positioned on the image side of the second lens and is in at least partial contact with the image side surface of the second lens. The third support member is positioned on the image side of the third lens and is in at least partial contact with the image side surface of the third lens. The fourth support member is positioned on the image side of the fourth lens and is in at least partial contact with the image side surface of the fourth lens.

It should be understood that this application does not specifically limit the number of support members, and 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 excess refractive and reflective light paths, reducing stray light and ghosting. Adding auxiliary supports between the support members and the lens barrel helps to improve problems such as poor assembly stability and low performance yield caused by large step differences between lenses.

[0047] In an exemplary embodiment, a center thickness of the fifth lens on the optical axis is greater than center thicknesses of other lenses in the lens group on the optical axis.

[0048] In an exemplary embodiment, the camera lens according to the present application can satisfy: -4.8 < R10 / (EP45 × N5) < -2.55, where R10 is the radius of curvature of the image side of the fifth lens, EP45 is the distance along the optical axis from the image side of the fourth bearing member to the object side of the fifth bearing member, and N5 is the refractive index of the fifth lens. In this camera lens, the fifth lens is the lens with the thickest center thickness and has a big belly shape. The edge thickness of the fifth lens needs to match the center thickness. By reasonably setting the curvature, edge thickness, and material of the fifth lens, the forming difficulty of the fifth lens is reduced.

[0049] In an exemplary embodiment, the camera lens according to the present application can satisfy: 5.6 mm < f5 / (CP5 × d5m) < 10.4 mm, where f5 is the effective focal length of the fifth lens, CP5 is the maximum thickness of the fifth bearing member along the optical axis, and d5m is the inner diameter of the image side of the fifth bearing member.

[0050] In an exemplary embodiment, the camera lens according to the present application can satisfy: -5.45 mm < f6 / (D5m / d5m) < -1.0 mm, where f6 is the effective focal length of the sixth lens, D5m is the outer diameter of the image side of the fifth bearing member, and d5m is the inner diameter of the image side of the fifth bearing member.

[0051] In an exemplary embodiment, the maximum semi-field angle Semi-FOV of the camera lens according to the present application can be in the range of 50° to 60°, and the aperture number Fno can be, for example, in the range of 2.0 to 2.5.

[0052] The camera lens according to an exemplary embodiment of the present application is a six-piece wide-angle lens, including: 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, a second lens, a third lens, a fourth lens, a fifth lens, and a sixth lens. Among them, the first lens has a negative optical power, and both its object side and image side are concave surfaces; the second lens has a positive optical power; the third lens has a positive optical power, and both its object side and image side are convex surfaces; the fourth lens has a negative optical power, and its image side is a concave surface; the fifth lens has a positive optical power, and both its object side and image side are convex surfaces; and the sixth lens has a negative optical power, its object side is a convex surface, and its image side is a concave surface; the support member group includes: a fourth support member disposed on the image side of the fourth lens and at least partially contacting the image side of the fourth lens, and a fifth support member disposed on the image side of the fifth lens and at least partially contacting the image side of the fifth lens; the central thickness of the fifth lens on the optical axis is greater than the central thicknesses of the other lenses in the lens group on the optical axis; the radius of curvature R10 of the image side of the fifth lens, the distance EP45 along the optical axis from the image side of the fourth support member to the object side of the fifth support member, and the refractive index N5 of the fifth lens satisfy: -4.8 < R10 / EP45 × N5 < -2.55; the effective focal length f5 of the fifth lens, the maximum thickness CP5 of the fifth support member along the optical axis, and the inner diameter d5m of the image side of the fifth support member satisfy: 5.6 mm < f5 / CP5 × d5m < 10.4 mm; the effective focal length f6 of the sixth lens, the outer diameter D5m of the image side of the fifth support member, and the inner diameter d5m of the image side of the fifth support member satisfy: -5.45 mm < f6 / (D5m / d5m) < -1.0 mm. This camera lens meets the wide-angle characteristics of the lens by reasonably setting the optical power and surface type of the lenses. Among all the lenses, due to the limitations of the overall shape and material of the fifth lens, the fifth lens has the largest central thickness and satisfies -4.8 < R10 / EP45 × N5 < -2.55. At the same time, the sixth lens is the lens with the largest diameter. Therefore, it is easy for light to generate internal reflection stray light within the sixth lens after passing through the fifth lens. By controlling the distance EP45 along the optical axis from the image side of the fourth support member to the object side of the fifth support member, it is equivalent to controlling the maximum thickness of the non-light-transmitting area of the fifth lens. Further, in the present application, by controlling the relationship between the effective focal length of the fifth lens, the maximum thickness of the fifth support member, and the inner diameter of the image side, and the relationship between the effective focal length of the sixth lens and the outer diameter and inner diameter of the image side of the fifth support member, the refraction path of light passing through the fifth lens and the sixth lens can be restricted. By reasonably setting the thickness and the inner and outer diameters of the image side of the fifth support member, it is also possible to effectively block the excess marginal light after passing through the fifth lens, absorb the internal reflection stray light generated within the sixth lens, and adjust the structure of the non-light-transmitting area of the sixth lens to improve the stray light problem.

[0053] This application satisfies the conditional expressions 5.6 mm < f5 / CP5 × d5m < 10.4 mm and -5.45 mm < f6 / (D5m / d5m) < -1.0 mm, which can constrain the refraction of light passing through the fifth lens and the sixth lens. By reasonably setting the thickness of the fifth bearing member and the inner and outer diameters of the image side, it is also possible to effectively block the excess marginal light after passing through the fifth lens, while absorbing the internal reflection stray light generated in the sixth lens, adjusting the structure of the non-light-transmitting area of the sixth lens, and improving the stray light problem. The following further illustrates the effect of the technical solution of this application on improving stray light in combination with Figures 2A to 2C , further explaining the role of the technical solution of this application in improving stray light.

[0054] Exemplarily, Figure 2A shows the simulation diagram of the stray light spot at the sixth lens of a camera lens according to this application when R10 / EP45×N5 = -2.8, f5 / CP5×d5m = 7.5, and f6 / (D5m / d5m) = -3.5. Figure 2B shows the simulation diagram of the stray light spot at the sixth lens of a camera lens according to this application when R10 / EP45×N5 = -2.8, f5 / CP5×d5m = 12.0, and f6 / (D5m / d5m) = -0.5. Figure 2C shows the simulation diagram of the stray light spot at the sixth lens of a camera lens according to this application when R10 / EP45×N5 = -2.8, f5 / CP5×d5m = 2.5, and f6 / (D5m / d5m) = -7.5. Through the comparison of Figures 2A to 2C , it can be found that Figure 2A when the values of f5 / CP5×d5m and f6 / (D5m / d5m) are within the scope of this application, the stray light spots are fewer and the energy is weaker, while Figure 2B and Figure 2C when the values of f5 / CP5×d5m and f6 / (D5m / d5m) are not within the scope of this application, the distribution range of the stray light spots is wide and the energy is strong.

[0055] 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 sequentially includes, 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. Among them, the first lens has a negative optical power, and both its object side surface and image side surface are concave surfaces; the second lens has a positive optical power; the third lens has a positive optical power, and both its object side surface and image side surface are convex surfaces; the fourth lens has a negative optical power, and its image side surface is a concave surface; the fifth lens has a positive optical power, and both its object side surface and image side surface are convex surfaces; and the sixth lens has a negative optical power, its object side surface is a convex surface, and its image side surface is a concave surface; the support member group includes: a fourth support member disposed on the image side of the fourth lens and at least partially contacting the image side surface of the fourth lens, and a fifth support member disposed on the image side of the fifth lens and at least partially contacting the image side surface of the fifth lens; the central thickness of the fifth lens on the optical axis is greater than the central thicknesses of the other lenses in the lens group on the optical axis; the radius of curvature R10 of the image side surface of the fifth lens, the distance EP45 along the optical axis direction from the image side surface of the fourth support member to the object side surface of the fifth support member, and the refractive index N5 of the fifth lens satisfy: -4.8 < R10 / EP45 × N5 < -2.55; the Abbe number V5 of the fifth lens, the Abbe number V6 of the sixth lens, and the Abbe number V4 of the fourth lens satisfy: 1.35 < V5 / (V6 + V4) < 1.6; and the maximum thickness CP5 of the fifth support member along the optical axis direction and the maximum thickness CP4 of the fourth support member along the optical axis direction satisfy: 19.4 < CP5 / CP4 < 23.9. In this camera lens, the fifth lens is the lens with the thickest central thickness, showing a big-belly shape. The edge thickness of the fifth lens needs to be coordinated with the central thickness. By reasonably setting the curvature, edge thickness, and material of the fifth lens, the forming difficulty of the fifth lens is reduced. Reasonably setting the Abbe numbers of the fourth lens, the fifth lens, and the sixth lens helps to ensure the requirements of CAR in the lens specifications. At the same time, by controlling the maximum thicknesses of the fourth support member and the fifth support member, the edge thickness of the fifth lens can be ensured to be within a reasonable range, improving the yield of die-casting molding, ensuring that the PV value of the effective diameter region of the fifth lens meets the specification requirements, and improving the imaging quality.

[0056] In an exemplary embodiment, the camera lens according to the present application can satisfy: 2.05 < CT5 / EP45 < 2.8, where CT5 is the central thickness of the fifth lens on the optical axis, and EP45 is the distance along the optical axis direction from the image side of the fourth bearing member to the object side of the fifth bearing member. It can be understood that EP45 can limit the maximum thickness of the non-light-transmitting area of the fifth lens. The present application reasonably controls the edge thickness of the fifth lens and the central thickness of the fifth lens on the optical axis to satisfy 2.05 < CT5 / EP45 < 2.8, which can ensure that the fifth lens has good processing feasibility, and effectively ensure the accuracy of the bearing position between the fifth lens and the adjacent lenses after assembly, so that the optical parameters of the lens meet the design requirements. At the same time, reasonably controlling the edge thickness of the fifth lens and the central thickness of the fifth lens on the optical axis can also prevent interference between the effective diameter surfaces of the fifth lens and the adjacent lenses in the optical axis direction after assembly, avoid appearance problems and performance anomalies of the lens, and improve the appearance and performance yield.

[0057] In an exemplary embodiment, the camera lens according to the present application can satisfy: 0.35 < (∑CT - CT5) / L < 0.53, where ∑CT is the sum of the central thicknesses of the first lens to the sixth lens on the optical axis, CT5 is the central thickness of the fifth lens on the optical axis, and L is the maximum height of the lens barrel along the optical axis direction. The fifth lens is the lens with the largest central thickness and has a big belly shape. When 0.35 < (∑CT - CT5) / L < 0.53, it is beneficial to ensure that the central thickness of the fifth lens is not too large, leaving enough space for other lenses, ensuring that the first lens and the sixth lens will not exceed the front and rear end faces of the lens barrel after assembly, and leaving enough gaps, so that there is no risk that the lens will protrude from the front and rear end faces of the lens barrel under the expected collision specifications, and improving the ability of the lens to withstand physical collisions.

[0058] In an exemplary embodiment, the camera lens according to the present application can satisfy: 0.6 < f45 / d4s < 1.45, where f45 is the combined focal length of the fourth lens and the fifth lens, and d4s is the inner diameter of the object side of the fourth bearing member. When 0.6 < f45 / d4s < 1.45, it is beneficial for light to enter the fourth lens and be better transmitted. The object side of the fourth lens converges the light, ensuring that the light energy transmission is more complete and the light energy transmission rate is higher. Controlling the inner diameter of the object side of the fourth bearing member helps to improve stray light, thereby improving the imaging quality of the lens.

[0059] In an exemplary embodiment, the camera lens according to the present application may satisfy: 4.5 < (|R10| + R11) / CP5 < 6.3, where R10 is the radius of curvature of the image side of the fifth lens, R11 is the radius of curvature of the object side of the sixth lens, and CP5 is the maximum thickness of the fifth bearing member along the optical axis direction. When 4.5 < (|R10| + R11) / CP5 < 6.3 is satisfied, it is beneficial to ensure the assembly requirements of the camera lens. The radius of curvature of the image side of the fifth lens and the radius of curvature of the object side of the sixth lens restrict the surface shape trends of the fifth lens and the sixth lens, and at the same time affect the maximum thickness CP5 of the fifth bearing member. The closer the maximum thickness CP5 of the fifth bearing member is to the distance at the position of the maximum effective diameter of the adjacent lenses on both sides of the fifth bearing member, the more obvious the improvement in the assembly stability of the lens, and the better the assembly stability of the lens.

[0060] In an exemplary embodiment, the radius of curvature of the object side of the fifth lens of the camera lens according to the present application is greater than zero, and the camera lens may satisfy: 0.6 < (EP34 + EP45) / (CT4 + CT5) < 0.95, where EP34 is the distance along the optical axis direction from the image side of the third bearing member to the object side of the fourth bearing member, EP45 is the distance along the optical axis direction from the image side of the fourth bearing member to the object side of the fifth bearing member, CT4 is the central thickness of the fourth lens on the optical axis, and CT5 is the central thickness of the fifth lens on the optical axis. Affected by the air gap between the third lens and the fourth lens, the edge thicknesses of the third lens and the fourth lens are in a complementary relationship. When one thickens, the other needs to thin. At the same time, the edge thickness of the fourth lens (i.e., EP45) and the central thickness CT4 of the fourth lens on the optical axis determine the forming difficulty of the fourth lens, and the central thickness CT5 of the fifth lens on the optical axis determines the forming difficulty of the fifth lens. When 0.6 < (EP34 + EP45) / (CT4 + CT5) < 0.95 is satisfied, the edge thicknesses of the third lens and the fourth lens can be balanced, and the forming difficulties of the fourth lens and the fifth lens can be reduced.

[0061] In an exemplary embodiment, the camera lens according to the present application may satisfy: 3.85 mm < d0m / (f / f56) < 5.25 mm, where d0m is the inner diameter of the image-side end face of the lens barrel, f is the effective focal length of the camera lens, and f56 is the combined focal length of the fifth lens and the sixth lens. When 3.85 mm < d0m / (f / f56) < 5.25 mm is satisfied, it is beneficial to ensure the performance and appearance of the camera lens, ensure the matching degree between the camera lens and the chip during design, effectively control the rear-end size and the height of the lens barrel of the lens, contribute to the miniaturization characteristics of the lens, and effectively ensure the imaging quality.

[0062] In an exemplary embodiment, the camera lens according to the present application can satisfy: 1.35 < V5 / (V6 + V4) < 1.6 and 19.4 < CP5 / CP4 < 23.9, where V5 is the Abbe number of the fifth lens, V6 is the Abbe number of the sixth lens, V4 is the Abbe number of the fourth lens, CP5 is the maximum thickness of the fifth bearing member along the optical axis direction, and CP4 is the maximum thickness of the fourth bearing member along the optical axis direction. Controlling the Abbe numbers of the fourth lens, the fifth lens, and the sixth lens to satisfy 1.35 < V5 / (V6 + V4) < 1.6 helps to ensure the requirements of CAR in the lens specifications. At the same time, controlling the maximum thicknesses of the fourth bearing member and the fifth bearing member to satisfy 19.4 < CP5 / CP4 < 23.9 can ensure that the edge thickness of the fifth lens is within a reasonable range, improve the die-casting molding yield, ensure that the PV value in the effective diameter region of the fifth lens meets the specification requirements, and improve the imaging quality.

[0063] In an exemplary embodiment, the camera lens according to the present application can satisfy: 5.65 < CT5 / (T56 + T45) < 10.0 and 1.3 < L / ∑CT < 1.6, where CT5 is the central thickness of the fifth lens on the optical axis, T56 is the air gap between the fifth lens and the sixth lens on the optical axis, T45 is the air gap between the fourth lens and the fifth lens on the optical axis, L is the maximum height of the lens barrel along the optical axis direction, and ∑CT is the sum of the central thicknesses of the first lens to the sixth lens on the optical axis. The fifth lens is the lens with the largest central thickness among all the lenses and is made of glass material. When 5.65 < CT5 / (T56 + T45) < 10.0, controlling the central thickness of the fifth lens and the adjacent air gaps before and after it can restrict the sensitivity related to the thickness of the fifth lens; controlling the ratio of the maximum height of the lens barrel to the sum of the central thicknesses of all the lenses to satisfy 1.3 < L / ∑CT < 1.6 is beneficial to reasonably control the spatial distribution of the lenses and the air gaps, and reduce the influence caused by the excessive space occupied by the excessive central thickness of the fifth lens.

[0064] In an exemplary embodiment, the imaging lens according to the present application may satisfy the following conditions: 0.8 < (DT62 - DT22) / (D5m - D2m) < 16.05, where DT62 is the effective semi-aperture of the image-side surface of the sixth lens element, DT22 is the effective semi-aperture of the image-side surface of the second lens element, D5m is the outer diameter of the image-side surface of the fifth supporting member, and D2m is the outer diameter of the image-side surface of the second supporting member. More specifically, the imaging lens according to the present application may further satisfy the following conditions: 0.8 < (DT62 - DT22) / (D5m - D2m) < 5.4. When 0.8<(DT62-DT22) / (D5m-D2m)<16.05 is satisfied, it helps to improve the assembly stability of the lens; among them, the outer diameter of the second lens determines the lowest position of the bearing contact position of all lenses and the supporting member, and the outer diameter of the sixth lens determines the highest position of the bearing contact position of all lenses and the supporting member. The smaller the difference between the lowest position and the highest position, the more obvious the improvement to the assembly stability of the lens, and the better the assembly stability of the lens.

[0065] In an exemplary embodiment, the camera lens according to the present application may satisfy the following conditions: 4.0<(D4m / d4m)+(CT5 / EP45)<4.6, wherein D4m is the outer diameter of the image side surface of the fourth support member, d4m is the inner diameter of the image side surface of the fourth support member, CT5 is the center thickness of the fifth lens on the optical axis, and 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. When 4.0<(D4m / d4m)+(CT5 / EP45)<4.6 is satisfied, the thickness of the non-light-transmitting area of the fifth lens can be controlled, and the size of the annular band that blocks light by the fourth support member can also be controlled to reduce the transmission of some non-imaging light caused by penetrating light between lenses. The fourth support member can effectively block the internal reflected stray light generated after passing through the fifth lens. Combined with the control of the shape of the non-light-transmitting area of the fifth lens, the internal reflected stray light can be effectively improved, thereby enhancing the imaging quality.

[0066] In an exemplary embodiment, the camera lens according to the present application can satisfy the following conditions: 0.3mm<(d5s-d4m) / N5<0.75mm, wherein d5s is the inner diameter of the object side surface of the fifth support member, d4m is the inner diameter of the image side surface of the fourth support member, and N5 is the refractive index of the fifth lens. The fifth lens is made of glass, and the fourth and fifth support members serve as annular optical elements before and after the fifth lens. By controlling the difference between the inner diameters of the image side surface of the fourth support member and the inner diameters of the object side surface of the fifth support member and the material ratio to satisfy 0.3mm<(d5s-d4m) / N5<0.75mm, it is beneficial to block excess light generated by the rear edge of the fifth lens through the fourth and fifth support members, effectively improving lens stray light.

[0067] In an exemplary embodiment, the camera lens according to the present application may satisfy: 2.95 < (D4m - DT51) / (SG51 + |SG52|) < 6.65, where D4m is the outer diameter of the image side of the fourth bearing member, DT51 is the effective semi-aperture of the object side of the fifth lens, SG51 is the distance along the optical axis from the intersection of the object side of the fifth lens and the optical axis to the image side of the fourth bearing member, and SG52 is the distance along the optical axis from the intersection of the image side of the fifth lens and the optical axis to the object side of the fifth bearing member. Since the fifth lens is a glass lens and not many shapes can be made on the lens structure, in this lens, the outer diameter of the image side of the fourth bearing member is close to the same height as the maximum outer diameter of the fifth lens. By controlling the difference between the outer diameter of the image side of the fourth bearing member and the effective semi-aperture of the object side of the fifth lens, as well as the front and rear curvatures of the fifth lens, and satisfying 2.95 < (D4m - DT51) / (SG51 + |SG52|) < 6.65, the overall shape of the fifth lens can be effectively controlled, and the molding difficulty of the fifth lens can be reduced.

[0068] In an exemplary embodiment, the camera lens according to the present application may satisfy: -3.26 < f56 / (SG52 + SG61) < -1.9, where f56 is the combined focal length of the fifth lens and the sixth lens, SG52 is the distance along the optical axis from the intersection of the image side of the fifth lens and the optical axis to the object side of the fifth bearing member, and SG61 is the distance along the optical axis from the intersection of the object side of the sixth lens and the optical axis to the image side of the fifth bearing member. SG52 and SG61 respectively control the maximum curvatures of the image side of the fifth lens and the object side of the sixth lens. The greater the curvature, the more difficult the lens molding is, and it is easy to appear red film color during lens coating, which increases the surface reflectivity of the lens and thus increases the risk of lens ghost images. The smaller the curvature, the simpler the lens molding is, and the reflectivity of the lens after coating is also smaller. The present application satisfies -3.26 < f56 / (SG52 + SG61) < -1.9, which helps to improve the molding and coating yields of the fifth lens and the sixth lens, and improve the imaging quality and overall yield of the lens.

[0069] In an exemplary embodiment, the camera lens according to the present application may satisfy: -2.1 < CT5 / SG52 < -1.75, where CT5 is the central thickness of the fifth lens on the optical axis, and SG52 is the distance along the optical axis from the intersection of the image side of the fifth lens and the optical axis to the object side of the fifth bearing member. Satisfying -2.1 < CT5 / SG52 < -1.75 helps to improve the refraction effect of the fifth lens and meet the requirements of lens miniaturization and high quality. The fifth lens is a lens with a relatively large refractive index. When both the lens volume is small and the imaging quality is high, within the limited space inside the lens, the utilization rate of the internal space of the lens is maximized. The fifth lens diverges the light rays at a larger angle to provide a larger image plane and clearer resolution.

[0070] 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 characteristic of an aspherical lens is that the curvature changes continuously from the center of the lens to the periphery of the lens. Unlike a spherical lens with a constant curvature from the center of the lens to the periphery of the lens, an aspherical lens has a better curvature radius characteristic, and has the advantages of improving distortion aberration and improving astigmatism aberration. After adopting an aspherical lens, the aberration that occurs during imaging can be eliminated as much as possible, thereby improving the imaging quality. Optionally, the object side surface and the image side surface of all lenses from the first lens to the sixth lens are aspherical mirror surfaces.

[0071] In an exemplary embodiment, the camera lens may further include a filter for correcting color deviation and / or a protective glass for protecting a photosensitive element located on the imaging surface.

[0072] The camera lens according to the above-described embodiment of the present application can use multiple lenses, such as the six lenses described above. By rationally allocating the optical power, surface shape, and arrangement of the supporting members of each lens, the span of each gear of the lens and the lens barrel is made more uniform, thereby enhancing the ability to converge light and improving the imaging quality of ultra-wide-angle and large-image-area camera lenses. However, those skilled in the art will understand that, without departing from the technical solution claimed in this application, the number of lenses constituting the camera lens can 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 embodiment, the camera lens is not limited to including six lenses. If necessary, the camera lens may also include other numbers of lenses.

[0073] The following further describes specific embodiments of the camera lens applicable to the above-mentioned embodiments with reference to the accompanying drawings. Figures 3A to 4C Describe the camera lenses 1001 and 1002 according to embodiments 1 and 2 of the present application; refer to Figures 5A to 6C Describe the camera lenses 2001 and 2002 according to embodiments 3 and 4 of the present application; refer to 7A to 8C The imaging lenses 3001 and 3002 according to Embodiments 5 and 6 of the present application are described.

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.
