[0042] It should be noted that, in the absence of conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

It should be pointed out that, for those of ordinary skill in the art, without departing from the concept of the present application, several deformations and improvements can also be made, which all belong to the protection scope of the present application. For example, the lens groups, lens barrels and supporting members in the various embodiments of the present application can be arbitrarily combined, and are not limited to the lens groups in one embodiment can only be combined with the lens barrels, supporting members, etc. of the embodiment.

[0043] The present application will be described in detail below with reference to the accompanying drawings and in combination with embodiments. Figure 1 The structure arrangement diagram of an optical imaging lens according to the present application and a schematic diagram of some parameters are shown. 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 shown in the figure. Figure 1 It is shown in Figure 1 Only some parameters of the lens barrel and the supporting member of an optical imaging lens of the present application are shown as examples to facilitate a better understanding of the present invention. Figure 1 As shown, EP01 is 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, EP23 is 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 is 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 is the distance from the fourth supporting member to the fifth supporting member along the optical axis direction, EP50 is the distance from the image side face of the fifth supporting member to the image side end face of the lens barrel along the optical axis direction, d0s is the inner diameter of the object side end face of the lens barrel, d0m is the inner diameter of the image side end face of the lens barrel, D1s is the outer diameter of the object side surface of the first supporting member, D1m is the outer diameter of the image side surface of the first supporting member, D2s is the outer diameter of the object side surface of the second supporting member, D4s is the outer diameter of the object side surface of the fourth supporting member, d4s is the inner diameter of the object side surface of the fourth supporting member, D5s is the outer diameter of the object side surface of the fifth supporting member, D5m is the outer diameter of the image side surface of the fifth supporting member, d5s is the inner diameter of the object side surface of the fifth supporting member, d4s is the inner diameter of the object side surface of the fourth supporting member, D3m is the outer diameter of the image side surface of the third supporting member, and d1s is the inner diameter of the object side surface of the first supporting member.

[0044] The optical imaging lens according to the exemplary embodiment of the present application may include a lens barrel, a lens group and a supporting member group arranged in the lens barrel. The lens group may include, in order from the object side to the image side along the optical axis: a first lens with positive optical power, a second lens with positive optical power or negative optical power, a third lens with negative optical power, a fourth lens with positive optical power, a fifth lens with positive optical power, and a sixth lens with negative optical power.

[0045] In an exemplary embodiment, the support member group of the optical imaging 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 disposed between the first lens and the second lens and at least partially contacts the image side surface of the first lens. The second support member is disposed between the second lens and the third lens and at least partially contacts the image side surface of the second lens. The third support member is disposed between the third lens and the fourth lens and at least partially contacts the image side surface of the third lens. The fourth support member is disposed between the fourth lens and the fifth lens and at least partially contacts the image side surface of the fourth lens. The fifth support member is disposed between the fifth lens and the sixth lens and at least partially contacts the image side surface of the fifth lens.

[0046] In an exemplary embodiment, the optical imaging lens may further include auxiliary support members disposed between the support members and the lenses. For example, the optical imaging lens may include at least one auxiliary spacer element disposed between the third support member and the fourth lens. Again, for example, the optical imaging lens may include at least one auxiliary spacer element disposed between the fifth support member and the sixth lens.

[0047] It should be understood that the present application does not specifically limit the number of support members. Any number of support members may be included between any two lenses, and any number of support members may also be included in the entire optical imaging lens. The support members help the optical imaging lens intercept redundant refracted and reflected light paths, reducing the generation of stray light and ghost images. Adding auxiliary supports between the support members and the lens barrel is beneficial to improving problems such as poor assembly stability and low performance yield due to large step differences between lenses.

[0048] In an exemplary embodiment, the optical imaging lens may further include a diaphragm for restricting the light beam to further improve the imaging quality of the optical lens. Exemplarily, the diaphragm may be disposed on the object side of the first lens. The diaphragm is beneficial for converging the light entering the optical lens, reducing the maximum aperture of the optical lens, and reducing the assembly sensitivity of the system. However, it should be noted that the position of the diaphragm disclosed herein is merely an example and not a limitation; in alternative embodiments, the diaphragm may also be disposed at other positions according to actual needs.

[0049] In an exemplary embodiment, the optical imaging lens according to the present application may satisfy: 1.4 < T45 / CT5 < 3.5, where T45 is the air interval between the fourth lens and the fifth lens on the optical axis, and CT5 is the central thickness of the fifth lens.

[0050] In an exemplary embodiment, the optical imaging lens according to the present application may satisfy: 8.5 < f45 / EP45 < 16, where f45 is the combined focal length of the fourth lens and the fifth lens, and EP45 is the distance along the optical axis from the image side surface of the fourth support member to the object side surface of the fifth support member.

[0051] In an exemplary embodiment, the optical imaging lens according to the present application may satisfy: 3 < f4 / d4s×N4 < 5, where f4 is the effective focal length of the fourth lens, d4s is the inner diameter of the object side surface of the fourth support member, and N4 is the refractive index of the fourth lens.

[0052] The optical imaging lens according to an exemplary embodiment of the present application includes: a lens barrel, and a lens group and a support member group disposed in the lens barrel. The lens group sequentially includes, along the optical axis, from the object side to the image side: a first lens with a positive optical power, a second lens with a positive or negative optical power, a third lens with a negative optical power, a fourth lens with a positive optical power, a fifth lens with a positive optical power, and a sixth lens with a negative optical power. The support member group may include: a fourth support member and a fifth support member. The fourth support member is disposed between the fourth lens and the fifth lens and at least partially contacts the image side surface of the fourth lens. The fifth support member is disposed between the fifth lens and the sixth lens and at least partially contacts the image side surface of the fifth lens. The air interval T45 between the fourth lens and the fifth lens on the optical axis and the central thickness CT5 of the fifth lens satisfy: 1.4 < T45 / CT5 < 3.5. In this case, there is a relatively large interval distance between the fourth lens and the fifth lens, and it is easy to generate stray light problems that are difficult to improve between the fourth lens and the fifth lens. The present application further satisfies 8.5 < f45 / EP45 < 16 and 3 < f4 / d4s×N4 < 5. By adjusting the distance and air gap of the fourth support member and the fifth support member on the optical axis, the propagation space of light is reduced, and the generation of stray light is effectively suppressed. Reducing the inner diameter of the object side surface of the fourth support member can effectively block stray light. Controlling the effective focal length of the fourth lens, the combined focal length of the fourth lens and the fifth lens, and the refractive index of the fourth lens can effectively reduce the refraction angle of light and suppress the generation of stray light.

[0053] By controlling the conditional expressions T45 / CT5, f45 / EP45, and f4 / d4s×N4 within a reasonable range, that is, satisfying 1.4 < T45 / CT5 < 3.5, 8.5 < f45 / EP45 < 16, and 3 < f4 / d4s×N4 < 5, the design of the fourth support member and the fifth support member of the optical imaging lens provided by the present application is more reasonable. At the same time, by controlling the effective focal length of the fourth lens, the combined focal length of the fourth lens and the fifth lens, and the refractive index of the fourth lens, the beneficial effect of effectively suppressing stray light is achieved. The following combines Figures 8 to 11 to further illustrate that the optical imaging lens of the present application has the above beneficial effects.

[0054] Figure 8 and Fig.11 The T45 / CT5, f45 / EP45, and f4 / d4s×N4 of Figure 8 and Fig.11the stray light spots at the imaging surface therein are fewer and have weaker energy, while Fig. 9 and Fig.10 the T45 / CT5, f45 / EP45, and f4 / d4s×N4 of Fig. 9 and Fig.10 do not meet the above ranges of this application, and the distribution range of the stray light spots at the imaging surface in

[0055] In an exemplary embodiment, the optical imaging lens according to the present application can satisfy: 0.5 < R11 / R12 < 1.8 and -16 < f6 / V6 / D5m < -3, where R11 is the curvature radius of the object side surface of the sixth lens, R12 is the curvature radius of the image side surface of the sixth lens, f6 is the effective focal length of the sixth lens, V6 is the Abbe number of the sixth lens, and D5m is the outer diameter of the image side surface of the fifth support member. Satisfying 0.5 < R11 / R12 < 1.8 and -16 < f6 / V6 / D5m < -3 can effectively optimize the chromatic aberration of the optical imaging lens and the purple edge phenomenon that appears at the imaging edge. By controlling the curvature radius and focal length of the sixth lens, the divergence degree of different color lights can be reduced, and the chromatic aberration can be reduced; by controlling the Abbe number of the sixth lens and the outer diameter of the image side surface of the fifth support member, the dispersion phenomenon when the light enters and exits can be reduced, and the chromatic aberration can be greatly optimized.

[0056] In an exemplary embodiment, the optical imaging lens according to the present application can satisfy: 2.5 < EPD / (d0s - d0m) < 5.0, where d0s is the inner diameter of the object side end surface of the lens barrel, d0m is the inner diameter of the image side end surface of the lens barrel, and EPD is the entrance pupil diameter of the optical imaging lens. Satisfying 2.5 < EPD / (d0s - d0m) < 5.0 can effectively improve the stray light. By controlling the inner diameter of the object side end surface of the lens barrel and the entrance pupil size, the amount of light entering the optical imaging lens can be adjusted, the probability of generating stray light can be reduced, and the imaging quality can be optimized.

[0057] In an exemplary embodiment, the optical imaging lens according to the present application can satisfy: 1.1 < EP50 / CT6 < 4.7, where EP50 is the distance from the image side surface of the fifth support member to the image side end surface of the lens barrel along the optical axis direction, and CT6 is the central thickness of the sixth lens on the optical axis. Satisfying 1.1 < EP50 / CT6 < 4.7 can effectively control the thickness of the lens, improve the processing and forming quality of the lens, reduce the influence of internal stress on its performance, and improve the performance of the optical imaging lens.

[0058] In an exemplary embodiment, the optical imaging lens according to the present application may satisfy: 0 < D5m × V5 / f5 < 7, where D5m is the outer diameter of the image side of the fifth supporting member, V5 is the Abbe number of the fifth lens, and f5 is the effective focal length of the fifth lens. Satisfying 0 < D5m × V5 / f5 < 7 can effectively improve imaging chromatic aberration and purple fringing. Reasonably setting the effective focal length and Abbe number of the fifth lens can reduce chromatic dispersion. Controlling the outer diameter of the image side of the fifth supporting member can reduce the light incident aperture, reduce chromatic aberration, and optimize imaging.

[0059] In an exemplary embodiment, the optical imaging lens according to the present application may satisfy: 0.2 < (D5s - d5s) / (D4s - d4s) < 1.2, where D5s is the outer diameter of the object side of the fifth supporting member, d5s is the inner diameter of the object side of the fifth supporting member, D4s is the outer diameter of the object side of the fourth supporting member, and d4s is the inner diameter of the object side of the fourth supporting member. Satisfying 0.2 < (D5s - d5s) / (D4s - d4s) < 1.2 can effectively avoid problems such as light leakage and stray light that affect imaging quality due to deformation of the supporting member caused by the long cantilever effect during the baking process of the lens.

[0060] In an exemplary embodiment, the optical imaging lens according to the present application may satisfy: 1 < T45 / EP45 < 2.5, where EP45 is the distance between the fourth supporting member and the fifth supporting member along the optical axis direction, and T45 is the air gap between the fourth lens and the fifth lens on the optical axis. Satisfying 1 < T45 / EP45 < 2.5 can effectively increase the edge thickness of the fourth lens and reduce the influence of unstable assembly caused by a large air gap.

[0061] In an exemplary embodiment, the optical imaging lens according to the present application may satisfy: 0.1 < EP34 / (T34 + CT4) < 1.1, where EP34 is the distance between the image side of the third supporting member and the object side of the fourth supporting member along the optical axis direction, T34 is the air gap between the third lens and the fourth lens on the optical axis, and CT4 is the central thickness of the fourth lens on the optical axis. Satisfying 0.1 < EP34 / (T34 + CT4) < 1.1 is beneficial to improving the structural strength of the lens, effectively improving assembly instability, increasing the assembly yield rate, and making the imaging performance of the lens more stable.

[0062] In an exemplary embodiment, the optical imaging lens according to the present application may satisfy: 1.5 < f4 / R7 < 5 and 0.8 < f4 / D3m < 2.1, where f4 is the effective focal length of the fourth lens, R7 is the radius of curvature of the object side surface of the fourth lens, and D3m is the outer diameter of the image side surface of the third bearing member. Satisfying 1.5 < f4 / R7 < 5 and 0.8 < f4 / D3m < 2.1 can effectively reduce the influence of the fourth lens on the overall chromatic aberration of the lens, control the radius of curvature and effective focal length of the fourth lens, suppress the degree of refraction of light, suppress the degree of light divergence, weaken the purple fringing phenomenon at the imaging edge, and control the outer diameter of the third bearing member, which can reduce the amount of light entering the third lens and can suppress the generation of chromatic aberration.

[0063] In an exemplary embodiment, the optical imaging lens according to the present application may satisfy: 0.2 < EP23 / (CT2 + CT3) < 1.3, where EP23 is the distance along the optical axis from the image side surface of the second bearing member to the object side surface of the third bearing member, CT2 is the central thickness of the second lens on the optical axis, and CT3 is the central thickness of the third lens on the optical axis.

[0064] In an exemplary embodiment, the optical imaging lens according to the present application may satisfy: 0.8 < EP01 / SAG11 < 2, where EP01 is the distance along the optical axis from the object side end surface of the lens barrel to the object side surface of the first bearing member, and SAG11 is the axial distance between the intersection of the object side surface of the first lens and the optical axis and the vertex of the effective radius of the object side surface of the first lens. Satisfying 0.8 < EP01 / SAG11 < 2 can effectively ensure the supporting effect of the lens barrel on the lens and can protect the object side surface of the first lens at the same time.

[0065] In an exemplary embodiment, the optical imaging lens according to the present application may satisfy: 2.5 < f1 / (D1s - d1s) < 8, where f1 is the effective focal length of the first lens, d1s is the inner diameter of the object side surface of the first bearing member, and D1s is the outer diameter of the object side surface of the first bearing member. Satisfying 2.5 < f1 / (D1s - d1s) < 8 can effectively block the stray light generated by internal reflection of the first lens through the object side surface of the first bearing member and improve the imaging quality.

[0066] In an exemplary embodiment, the optical imaging lens according to the present application may satisfy: 1 < SAG32 / CT3 < 2.6 and 0.2 < SAG32 / EP23 < 1.4, where SAG32 is the axial distance between the intersection of the image side of the third lens and the optical axis and the vertex of the effective radius of the image side of the third lens, and EP23 is the distance along the optical axis from the central thickness CT3 of the third lens to the object side of the third support member from the image side of the second support member. Satisfying 1 < SAG32 / CT3 < 2.6 and 0.2 < SAG32 / EP23 < 1.4 can effectively improve the structural strength of the third lens, reduce the air gap, enhance the assembly stability, and improve the assembly yield.

Satisfying 0 < f12 / (D1m + D2s) < 2 can effectively suppress the generation of chromatic aberration. By controlling the outer diameters of the first support member and the second support member, the light flux of the optical imaging lens can be controlled, chromatic aberration can be effectively improved, and the imaging quality can be enhanced.

[0068] The optical imaging 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.

By controlling the curvature radius and focal length of the sixth lens, the divergence degree of different color lights can be reduced, and chromatic aberration can be decreased; by controlling the Abbe number of the sixth lens and the outer diameter of the image side of the fifth support member, the dispersion phenomenon when light enters and exits can be reduced, and the chromatic aberration can be greatly optimized.

[0069] An optical imaging 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 with a positive optical power, a second lens with a positive or negative optical power, a third lens with a negative optical power, a fourth lens with a positive optical power, a fifth lens with a positive optical power, and a sixth lens with a negative optical power. The support member group may include: a third support member disposed between the third lens and the fourth lens and at least partially in contact with the image side surface of the third lens; the effective focal length f4 of the fourth lens and the curvature radius R7 of the object side surface of the fourth lens satisfy: 1.5 < f4 / R7 < 5; and the effective focal length f4 of the fourth lens and the outer diameter D3m of the image side surface of the third support member satisfy: 0.8 < f4 / D3m < 2.1.

[0070] In an embodiment of the present application, at least one of the lens surfaces of each lens is an aspherical lens surface, that is, at least one of the lens surfaces from the object side surface of the first lens to the image side surface of the sixth lens is an aspherical lens surface. The characteristic of an aspherical lens is that the curvature changes continuously from the center of the lens to the periphery of the lens. Different from a spherical lens with a constant curvature from the center of the lens to the periphery of the lens, an aspherical lens has better 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 the imaging quality. Optionally, the object side surfaces and image side surfaces of all the lenses from the first lens to the sixth lens are aspherical lens surfaces.

[0071] 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.

[0072] The optical imaging lens according to the above-mentioned embodiment of the present application may use 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, which enhances the ability of light convergence and improves the imaging quality of the optical imaging lens. However, those skilled in the art should understand that the number of lenses constituting the optical imaging lens can be changed to obtain the various results and advantages described in this specification without departing from the technical solution claimed in the present application. For example, although six lenses are described as an example in the embodiment, the optical imaging lens is not limited to including six lenses. If necessary, the optical imaging lens may also include other numbers of lenses.
