Description

Technical Field

[0001] This application relates to the field of optical components, and more specifically, to an optical imaging lens. Background Technology

[0002] With the development of science and technology, the requirements for mobile phone lenses in terms of specifications have become very high. High-standard and high-specification mobile phone lenses generally adopt a 6-element, 7-element, or 8-element architecture. Through full optimization of optical design, the imaging quality of the lens can be greatly improved. However, with the increase in the number of lens elements, more tolerances are introduced into the lens, which greatly increases the difficulty in lens design and assembly, and the cost also increases exponentially. This is more suitable for high-end flagship mobile phone series.

[0003] The more lens elements there are, the more tolerances the lens has, leading to higher lens sensitivity and making it more difficult to improve the overall lens yield. For 6-element lenses, significant radial differences can easily occur between the third and fourth lenses, or between the fourth and fifth lenses, as well as between the front and rear ends of the lens. Improper distribution of lens thickness and mounting components can easily cause internal stray light phenomena. Furthermore, the stability of the mounting between the lenses and the mounting components significantly affects the overall image quality of the lens. How to design mounting components rationally while ensuring good image quality and improving the overall lens yield has always been a focus of research in this field. Summary of the Invention

[0016] In one embodiment, the maximum central thickness CTmax of the first to sixth lenses along the optical axis, and the maximum thickness CPn of the bearing member along the optical axis of the lens with the largest central thickness along the optical axis, which is located on the image side of the first to sixth lenses and at least partially in contact with the image side of that lens, satisfy: 21.5 <CTmax / CPn<55.2。

[0017] In one embodiment, the distance EP45 between the fourth and fifth support members along the optical axis, the effective focal length f5 of the fifth lens, and the combined focal length f56 of the fifth and sixth lenses satisfy: 0.4mm. <EP45 / |(f5 / f56)|<2.0mm。

[0020] This application provides a six-element optical imaging lens. By adjusting the distribution of the lenses and supporting components, the processing and structural stability of the lens are ensured, thereby improving the lens MTF yield. The optical imaging lens provided by this application satisfies: 0 < (f1 / R1) / (T12 / CP1) < 1.8 and 0.5mm < (d3s×CP3) / f3+f45 / (D5s / d4s) < 3.0mm. This constrains the effective focal length of the first lens and the radius of curvature of the object side surface, the maximum thickness of the first supporting component, and the ratio between the air gaps on the optical axis of the first and second lenses. This helps to constrain the center thickness of the first lens, ensuring the structural strength of the first lens and the stability of the support between the first and second lenses; at the same time, it constrains the effective focal length of the third lens, the radius of curvature of the object side surface, the maximum thickness of the first supporting component, and the ratio between the air gaps on the optical axis of the first and second lenses. The inner diameter of the object side of the three bearing members, the maximum thickness of the third bearing member, the combined focal length of the fourth and fifth lenses, the inner diameter of the object side of the fourth bearing member, and the outer diameter of the object side of the fifth bearing member can constrain the center thickness of the third, fourth, and fifth lenses, reduce lens sensitivity, and ensure that the third and fourth bearing members have sufficient bearing surface without obstructing effective light, so that the lenses on both sides can be stably supported. This reduces the problem of poor structural stability caused by the deformation of the front lens or bearing member by the lens assembled later due to the sharp increase in radial step difference, and improves the lens MTF yield.

[0039] The present application will now be described in detail with reference to the accompanying drawings and embodiments. Figure 1This diagram illustrates the structural layout and schematic diagram of some parameters of an optical imaging lens according to this application. Those skilled in the art will understand that some lens parameters commonly used in the art, such as the center thickness CT5 of the fifth lens on the optical axis, are not shown.

[0040] An optical imaging lens according to an exemplary embodiment of this application includes a lens barrel, a lens group disposed within the lens barrel, and a plurality of support members. The lens group includes, in sequence along the optical axis from the object side to the image side, a first lens, a second lens, a third lens, a fourth lens, a fifth lens, and a sixth lens.

[0041] In an exemplary embodiment, the first lens has positive optical power, the second lens has positive or negative optical power, the third lens has negative optical power, the fourth lens has positive or negative optical power, the fifth lens has positive optical power, and the sixth lens has negative optical power.

[0042] In an exemplary embodiment, the object-side surface of the fifth lens has at least one inflection point, and the image-side surface of the sixth lens has at least one inflection point.

[0043] In an exemplary embodiment, the plurality of bearing members of the optical imaging lens may include at least one of a first bearing member, a second bearing member, a third bearing member, a fourth bearing member, and a fifth bearing member. The first bearing member is positioned on the image side of the first lens and at least partially contacts the image side of the first lens. The second bearing member is positioned on the image side of the second lens and at least partially contacts the image side of the second lens. The third bearing member is positioned on the image side of the third lens and at least partially contacts the image side of the third lens. The fourth bearing member is positioned on the image side of the fourth lens and at least partially contacts the image side of the fourth lens. The fifth bearing member is positioned on the image side of the fifth lens and at least partially contacts the image side of the fifth lens. It should be understood that this application does not specifically limit the number of bearing members; any number of bearing members may be included between any two lenses, and the entire optical imaging lens may also include any number of bearing members. Bearing members help the optical imaging lens intercept excess reflective light paths, reducing stray light and ghosting. Adding auxiliary bearing between the bearing member and the lens barrel helps improve problems such as poor assembly stability and low performance yield caused by large step differences between lenses.

[0044] In an exemplary embodiment, the plurality of bearing members may include a first bearing member, a third bearing member, a fourth bearing member, and a fifth bearing member.

[0045] In an exemplary embodiment, the optical imaging lens according to this application can satisfy: 0<(f1 / R1) / (T12 / CP1)<1.8, where f1 is the effective focal length of the first lens, R1 is the radius of curvature of the object side of the first lens, CP1 is the maximum thickness of the first support member along the optical axis, and T12 is the air gap between the first lens and the second lens on the optical axis.

[0046] In an exemplary embodiment, the optical imaging lens according to this application can satisfy: 0.5mm < (d3s×CP3) / f3+f45 / (D5s / d4s) < 3.0mm, where f3 is the effective focal length of the third lens, d3s is the inner diameter of the object side of the third support member, CP3 is the maximum thickness of the third support member along the optical axis, f45 is the combined focal length of the fourth and fifth lenses, D5s is the outer diameter of the object side of the fifth support member, and d4s is the inner diameter of the object side of the fourth support member.

[0047] The optical imaging lens according to an exemplary embodiment of this application is a 6-element, small-head, ultra-thin lens. Large radial step differences are prone to occur between the third and fourth lenses, or between the fourth and fifth lenses, and the radial step difference between the front and rear ends of the lens is also large. The stability of the bearing between the lens and the support component significantly affects the overall image quality of the lens.

[0048] An optical imaging lens according to an exemplary embodiment of this application includes: a lens barrel and a lens group and a plurality of bearing members disposed within the lens barrel. The lens group, along the optical axis from the object side to the image side, sequentially includes: a first lens with positive optical power, a second lens with optical power, a third lens with negative optical power, a fourth lens with optical power, a fifth lens with positive optical power, and a sixth lens with negative optical power. The object side of the fifth lens has at least one inflection point, and the image side of the sixth lens has at least one inflection point. The plurality of bearing members include a first bearing member, a third bearing member, a fourth bearing member, and a fifth bearing member, and satisfy: 0 < (f1 / R1) / (T12 / CP1) < 1.8 and 0.5 mm < (d3s×CP3) / f3+f45 / (D5s / d4s) < 3.0 mm, constraining the effective focal length of the first lens and the half curvature of the object side. The ratio between the diameter, the maximum thickness of the first support member, and the air gap between the first and second lenses on the optical axis helps to constrain the center thickness of the first lens, ensuring the structural strength of the first lens and the stability of the support between the first and second lenses. At the same time, constraining the effective focal length of the third lens, the object-side inner diameter and maximum thickness of the third support member, the combined focal length of the fourth and fifth lenses, the object-side inner diameter of the fourth support member, and the object-side outer diameter of the fifth support member can constrain the center thickness of the third, fourth, and fifth lenses, reduce lens sensitivity, and ensure that the third and fourth support members have sufficient support surface without obstructing effective light, so that the lenses on both sides can support them stably. This reduces the problem of poor structural stability caused by the deformation of the front lens or support member by the lens assembled later due to the sharp increase in radial step difference, and improves the lens MTF yield.

[0049] The following, in conjunction with Tables 1-1 to 1-3, further illustrates the relationship between lens thickness and sensitivity. In Tables 1-1 to 1-3, the symbols “+” and “-” in +3μm and -3μm indicate the direction of fluctuation of the actual center thickness of the lens relative to the designed center thickness value of the lens.

[0050] Table 1-1 shows the sensitivity of the center thickness of the first to sixth lenses in Example 1 to the field curvature in the T direction when (d3s×CP3) / f3+f45 / (D5s / d4s)>3.0mm. For example, in a 1.0 field of view, when the actual center thickness of the first lens deviates by +3μm from the design value, the offset of the field curvature in the T direction is 27.93μm; when the actual center thickness of the first lens deviates by -3μm from the design value, the offset of the field curvature in the T direction is -25.82μm.

[0051] Table 1-2 shows the sensitivity of the center thickness of the first to sixth lenses in Example 1 to the field curvature in the T direction when (d3s×CP3) / f3+f45 / (D5s / d4s)<0.5mm. For example, in a 1.0 field of view, when the actual center thickness of the first lens deviates by +3μm from the design value, the offset of the field curvature in the T direction is 10.05μm; when the actual center thickness of the first lens deviates by -3μm from the design value, the offset of the field curvature in the T direction is -8.94μm.

[0052] Table 1-3 shows the sensitivity of the center thickness of the first to sixth lenses in Example 1 to the field curvature in the T direction when 0.5mm < (d3s×CP3) / f3+f45 / (D5s / d4s) < 3.0mm. For example, in a 1.0 field of view, when the actual center thickness of the first lens deviates by +3μm from the design value, the offset of the field curvature in the T direction is 3.72μm; when the actual center thickness of the first lens deviates by -3μm from the design value, the offset of the field curvature in the T direction is -2.98μm.

[0053] In Tables 1-1 and 1-2, the bolded data are all greater than 7μm. However, in Table 1-3, when the actual center thickness of the third lens deviates by +3μm from the design value at a 1.0 field of view, the offset of the field curvature in the T direction is 7.16μm. All other data are below 7μm. This shows that when 0.5mm < (d3s×CP3) / f3 + f45 / (D5s / d4s) < 3.0mm, the center thickness of each lens in Example 1 has low sensitivity to the field curvature in the T direction. The above only uses Example 1 as an example to illustrate that satisfying 0.5mm < (d3s×CP3) / f3 + f45 / (D5s / d4s) < 3.0mm helps reduce lens sensitivity and improve lens MTF yield. Other examples have the same effect and will not be elaborated further.

The optical imaging lens satisfies: 0.2 < |f5 / R10| × (EP45 / CT5) < 1.3, controlling the center thickness and edge thickness of the fifth lens within a relatively reasonable range, reducing the risk of welding marks during the molding of the fifth lens, thereby reducing the risk of stray light caused by welding marks, improving the cleanliness of the lens imaging, reducing the demolding force when the plastic lens is demolded after molding, reducing the surface shape deviation from the design curve caused by the demolding deformation of the lens, and improving the MTF quality of the lens.

[0061] The optical imaging lens according to an exemplary embodiment of the present application includes: a lens barrel, a lens group, and a plurality of supporting members 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 focal power, a third lens with a negative focal power, a fourth lens with a focal power, a fifth lens with a positive focal power, and a sixth lens with a negative focal power. Among them, the object side surface of the fifth lens has at least one inflection point, and the image side surface of the sixth lens has at least one inflection point; the plurality of supporting members include a first supporting member, a third supporting member, a fourth supporting member, and a fifth supporting member. The optical imaging lens satisfies: 4.8mm -1 <|f56 / (R10+R12) / (T56-CP5)|<13.0mm -1 , restricting the combined focal length of the fifth lens and the sixth lens, the radius of curvature of the object side surfaces of the fifth lens and the sixth lens, and the air gap on the optical axis and the maximum thickness of the fifth supporting member, facilitating the control of the overall shape of the fifth lens and the sixth lens and ensuring the stability of the air gap between the two lenses on the optical axis, and being more conducive to adjusting the field curvature and improving the lens performance in the later stage.

[0062] The optical imaging lens according to the present application can satisfy: 1.5 < D5s / d4s < 2.5, where D5s is the outer diameter of the object side surface of the fifth supporting member, and d4s is the inner diameter of the object side surface of the fourth supporting member. Satisfying 1.5 < D5s / d4s < 2.5 can reduce the problem of poor stability caused by a sudden increase in the radial step difference. The outer diameter of the object side surface of the fifth supporting member ensures the supporting stability of the two lenses closest to the image side.

[0063] In an exemplary embodiment, the radius of curvature of the object side surface of the first lens is greater than zero, the radius of curvature of the image side surface is less than zero, and the optical imaging lens according to the present application can satisfy: 1.0 < (D1s / d1s) + (R1 / R2) < 2.0, where D1s is the outer diameter of the object side surface of the first support member, d1s is the inner diameter of the object side surface of the first support member, R1 is the radius of curvature of the object side surface of the first lens, and R2 is the radius of curvature of the image side surface of the first lens. Satisfying 1.0 < (D1s / d1s) + (R1 / R2) < 2.0 can effectively improve the light blocking efficiency of the first support member and the stability of the first interval. Further, when the inner and outer diameters of the first support member are within this range, the baking deformation and assembly eccentricity of the first support member can be significantly reduced, and the light leakage and stray light caused by spacer deformation and assembly eccentricity can be reduced. In addition, after the radius of curvature of the first lens satisfies the above relationship, the gap stability after assembly can be ensured, and the degradation of the shooting performance caused by the change of the gap can be reduced.

[0064] In an exemplary embodiment, the radius of curvature of the object side surface of the fourth lens is less than zero, the radius of curvature of the object side surface of the fifth lens is greater than zero, and the optical imaging lens according to the present application can satisfy: 0.2 < |f5 / R10| × (EP45 / CT5) < 1.3, where f5 is the effective focal length of the fifth lens, R10 is the radius of curvature of the image side surface of the fifth lens, EP45 is the distance between the fourth support member and the fifth support member along the optical axis direction, and CT5 is the central thickness of the fifth lens on the optical axis. Satisfying 0.2 < |f5 / R10| × (EP45 / CT5) < 1.3, the central thickness and edge thickness of the fifth lens can be in a relatively reasonable range, reducing the risk of welding marks during the molding of the fifth lens, thereby reducing the risk of stray light caused by welding marks, improving the cleanliness of the lens imaging, reducing the demolding force when the plastic lens is demolded after molding, reducing the deviation of the surface shape from the designed curve caused by the demolding deformation of the lens, and improving the MTF quality of the lens.

[0065] In an exemplary embodiment, the optical imaging lens according to the present application can satisfy: 1.5 < R1 / R2 + D0s / d0smin < 2.0, where R1 is the radius of curvature of the object side surface of the first lens, R2 is the radius of curvature of the image side surface of the first lens, D0s is the outer diameter of the object side end surface of the lens barrel, and d0smin is the minimum inner diameter of the front end portion of the lens barrel facing the object side. Satisfying 1.5 < R1 / R2 + D0s / d0smin < 2.0, controlling the radius of curvature of the first lens is beneficial to reducing the processing angle and the aperture of the first lens; restricting the outer diameter of the object side end surface of the lens barrel and the minimum opening aperture is beneficial to the design of the head of the lens barrel without affecting the light, meeting the characteristics of a small head.

[0066] In an exemplary embodiment, the optical imaging lens according to the present application can satisfy: 4.8mm-1 <|f56 / (R10+R12) / (T56-CP5)|<13.0mm -1 Where f56 is the combined focal length of the fifth and sixth lenses, R10 is the radius of curvature of the image-side surface of the fifth lens, R12 is the radius of curvature of the image-side surface of the sixth lens, T56 is the air gap between the fifth and sixth lenses on the optical axis, and CP5 is the maximum thickness of the fifth support component along the optical axis. It must meet the requirement of 4.8mm. -1 <|f56 / (R10+R12) / (T56-CP5)|<13.0mm -1 This constrains the combined focal length of the fifth and sixth lenses, the radius of curvature of the object sides of the fifth and sixth lenses, the air gap on the optical axis, and the maximum thickness of the fifth support component. This facilitates the control of the overall shape of the fifth and sixth lenses and ensures the stability of the air gap between the two lenses on the optical axis, which is more conducive to adjusting field curvature and improving lens performance in the later stages.

[0067] In an exemplary embodiment, the optical imaging lens according to this application satisfies: 4.0 < (D3s - d3s) / (CP3 + T34) < 23.0, where D3s is the outer diameter of the object-side surface of the third support member, d3s is the inner diameter of the object-side surface of the third support member, CP3 is the maximum thickness of the third support member along the optical axis, and T34 is the air gap between the third lens and the fourth lens on the optical axis. Satisfying 4.0 < (D3s - d3s) / (CP3 + T34) < 23.0 constrains the air gap between the third lens and the fourth lens on the optical axis, as well as the maximum thickness of the third support member and the inner and outer diameters of the object-side surface. This facilitates stable support between the third lens, the fourth lens, and the third support member, reduces lens sensitivity, and improves lens performance.

[0068] In an exemplary embodiment, the optical imaging lens according to this application satisfies: 0 < (CP4 / T45) / (D4m / d4s) < 5.5, where CP4 is the maximum thickness of the fourth support member along the optical axis, T45 is the air gap between the fourth and fifth lenses on the optical axis, D4m is the outer diameter of the image-side surface of the fourth support member, and d4s is the inner diameter of the object-side surface of the fourth support member. By controlling CP4, T45, D4m, and d4s to satisfy the above relationship, the light-blocking efficiency of the fourth support member and the stability of the fourth gap can be effectively improved. Furthermore, when the inner and outer diameters of the fourth support member are within this range, the baking deformation and assembly misalignment of the fourth support member can be significantly reduced, ensuring the gap stability after assembly and reducing the decline in shooting performance caused by gap changes.

[0069] In an exemplary embodiment, the optical imaging lens according to the present application can satisfy: 0 < (D4m - D3m) / (f × tan(Semi-FOV)) < 1.0, where D4m is the outer diameter of the image side surface of the fourth supporting member, D3m is the outer diameter of the image side surface of the third supporting member, f is the effective focal length of the optical imaging lens, and Semi-FOV is the maximum half field angle of the optical imaging lens. Satisfying 0 < (D4m - D3m) / (f × tan(Semi-FOV)) < 1.0 is beneficial to controlling the outer diameters of the image side surfaces of the third supporting member and the fourth supporting member while forming a large viewing angle of the lens, obtaining a relatively stable aperture step difference. After assembling the third supporting member, the fourth lens, and the fourth supporting member, a stable step difference can be obtained, which can also ensure that the lens has the characteristics of a small volume and maintains high image quality.

[0070] In an exemplary embodiment, the optical imaging lens according to the present application can satisfy: (CP4 + CP5) / (T45 + T56) < 1.2, where CP4 is the maximum thickness of the fourth supporting member along the optical axis direction, CP5 is the maximum thickness of the fifth supporting member along the optical axis direction, T45 is the air gap between the fourth lens and the fifth lens on the optical axis, and T56 is the air gap between the fifth lens and the sixth lens on the optical axis. When the maximum thicknesses of the fourth supporting member and the fifth supporting member and the air gaps at their positions are controlled within the above ranges, it can be ensured that there will be no obvious deformation after the supporting members are assembled, and there will be no obvious deformation during the manufacturing process of high-temperature baking, improving the light blocking efficiency, reducing the risk of stray light, and improving the MTF performance of the lens group after assembly to obtain the best imaging effect.

[0071] In an exemplary embodiment, the optical imaging lens according to the present application can satisfy: 1.5 < EP23 / CT3 + CT4 / EP34 < 4.5, where EP23 is the distance between the second supporting member and the third supporting member along the optical axis direction, CT3 is the central thickness of the third lens on the optical axis, CT4 is the central thickness of the fourth lens on the optical axis, and EP34 is the distance between the third supporting member and the fourth supporting member along the optical axis direction. Satisfying 1.5 < EP23 / CT3 + CT4 / EP34 < 4.5, the central thicknesses and edge thicknesses of the third lens and the fourth lens can be in a relatively reasonable range, reducing the risk of welding marks during the molding of the third lens and the fourth lens, thereby reducing the risk of stray light caused by welding marks and improving the cleanliness of the lens imaging.

[0072] In an exemplary embodiment, the optical imaging lens according to the present application can satisfy: 21.5 < CTmax / CPn < 55.2, where CTmax is the maximum value of the central thicknesses of the first lens to the sixth lens on the optical axis, and CPn is the maximum thickness in the optical axis direction of the bearing member that is placed on the image side of the lens with the largest central thickness among the first lens to the sixth lens and at least partially contacts the image side surface of this lens. Satisfying 21.5 < CTmax / CPn < 55.2 is conducive to keeping the central thickness of the lens within a relatively reasonable range. In addition, controlling the maximum thickness of the bearing member that at least partially contacts the lens on the image side of the lens with the maximum central thickness of the optical imaging lens helps to avoid assembly interference and is more convenient for later adjustment of field curvature.

[0073] In an exemplary embodiment, the optical imaging lens according to the present application can satisfy: 0.4 mm < EP45 / |(f5 / f56)| < 2.0 mm, where EP45 is the distance between the fourth bearing member and the fifth bearing member in the optical axis direction, f5 is the effective focal length of the fifth lens, and f56 is the combined focal length of the fifth lens and the sixth lens. Satisfying 0.4 mm < EP45 / |(f5 / f56)| < 2.0 mm helps to balance the back-end focal length of the optical imaging lens by controlling the combined focal length of the fifth lens and the sixth lens, the effective focal length of the fifth lens, and the thickness of the edge of the fifth lens. The optical imaging lens can have a relatively stable imaging focal plane position and better stability during use.

[0074] In an exemplary embodiment, the optical imaging lens according to the present application can satisfy: 0.5 < V5 / V3 / (d5s / d3s) < 2.0, where V5 is the Abbe number of the fifth lens, V3 is the Abbe number of the third lens, d5s is the inner diameter of the object side surface of the fifth bearing member, and d3s is the inner diameter of the object side surface of the third bearing member. Satisfying 0.5 < V5 / V3 / (d5s / d3s) < 2.0 is conducive to the design of the third lens and the fifth lens and improves their molding feasibility; in addition, by controlling the inner diameters of the object side surfaces of the third bearing member and the fifth bearing member, it is beneficial to block the stray light paths generated by the third lens and the fifth lens and reduce the risk of stray light.

[0075] In an exemplary embodiment, the optical imaging lens according to the present application can satisfy: |Sag42 / EP34| < 2.0 and -1.0 < Sag51 / EP45 < 0, where reference Figure 10, Sag42 is the axial distance between the intersection of the image side of the fourth lens on the optical axis and the intersection of the object side of the fourth bearing member on the optical axis, Sag51 is the axial distance between the intersection of the object side of the fifth bearing member on the optical axis and the intersection of the image side of the fourth bearing member on the optical axis, EP34 is the spacing distance between the third bearing member and the fourth bearing member along the optical axis direction, and EP45 is the spacing distance between the fourth bearing member and the fifth bearing member along the optical axis direction. Satisfying |Sag42 / EP34| < 2.0 and -1.0 < Sag51 / EP45 < 0 can improve the smoothness and formability of the effective surface of the lens (the aspherical surface for transmitting effective light), ensure that the fourth lens and the fifth lens do not have a large curved surface shape, improve the stability during lens assembly, reduce assembly deformation, and improve imaging quality; at the same time, controlling the spacing distances between the third bearing member and the fourth bearing member and between the fourth bearing member and the fifth bearing member is beneficial to controlling the edge thicknesses of the fourth lens and the fifth lens, and is more conducive to their processing and forming.

[0076] 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 object side of the first lens to the image side of the sixth lens is an aspherical mirror surface. The characteristic of an aspherical lens is that the curvature continuously changes 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, an aspherical lens has better curvature radius characteristics and has the advantages of improving distortion aberration and improving astigmatism aberration. After using an aspherical lens, it is possible to eliminate the aberration that appears during imaging as much as possible, thereby improving imaging quality. Optionally, the object sides and image sides of all the lenses from the first lens to the sixth lens are aspherical mirror surfaces.

[0077] In an exemplary embodiment, the above optical imaging 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.

[0078] The optical imaging lens according to the above embodiment of the present application can use multiple lenses, such as the six lenses mentioned above. By reasonably distributing the optical power, surface shape of each lens, and the arrangement of each bearing member, etc., the span of each gear when the lens cooperates with the lens barrel is relatively uniform, enhancing the ability of light convergence and improving the imaging quality of the ultra-thin, large image plane optical imaging lens. 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 optical imaging lens can be changed to obtain the various results and advantages described in this specification. For example, although six lenses are used as an example in the embodiment, the optical imaging lens is not limited to including six lenses. If necessary, the optical imaging lens may further include other numbers of lenses.
