Description

Technical Field

[0001] This invention relates to the field of optical imaging equipment technology, and more specifically, to an optical camera lens. Background Technology

[0002] With the rapid advancement of intelligent technology in electronic products in recent years, the market's demand for diversified electronic products has been increasing. In many application scenarios, human-computer interaction has become increasingly important. To make electronic products more responsive and have a wider field of view in interactive experiences, the optical camera lenses mounted on these products need to have a large field of view. However, large field-of-view, seven-element optical camera lenses use a large number of lenses, which can easily generate internal reflection stray light on the lens surface. This stray light, along with the light rays participating in imaging, can severely affect image quality when it reaches the imaging plane. Especially if the front-end support of the optical camera lens cannot intercept stray light in time, the energy of subsequent stray light will be further superimposed, making it even more difficult to eliminate. Therefore, how to design the shape of the front-end lens and the inner diameter of the support of the optical camera lens to reduce stray light while ensuring a large field of view is an urgent problem to be solved. Summary of the Invention

[0003] The main objective of this invention is to provide an optical camera lens that solves the problem of severe stray light in existing optical camera lenses.

[0004] To achieve the above objectives, according to one aspect of the present invention, an optical camera lens is provided, comprising: seven lenses, the seven lenses being sequentially arranged from the object side to the image side of the optical camera lens, including a first lens to a seventh lens; a plurality of bearing members, at least including a second bearing member located on the image side of a second lens and at least partially in contact with the image side surface of the second lens; a lens barrel for accommodating the lenses and the bearing members; wherein the half field of view of the optical camera lens is greater than 100°; the radius of curvature R3 of the object side surface of the second lens, the radius of curvature R4 of the image side surface of the second lens, and the inner diameter d2s of the object side surface of the second bearing member satisfy the following: -2.8 < (R3 + R4) / d2s < -0.35.

[0005] According to another aspect of the present invention, an optical camera lens is provided, comprising: seven lenses, the seven lenses being sequentially arranged from the object side to the image side of the optical camera lens, including a first lens to a seventh lens; a plurality of bearing members, among which at least one second bearing member is located on the image side of a second lens and is at least partially in contact with the image side surface of the second lens; a lens barrel for accommodating the lenses and the bearing members; wherein the half field of view of the optical camera lens is greater than 100°; among the plurality of bearing members, at least one fifth bearing member is located on the image side of a fifth lens and is at least partially in contact with the image side surface of the fifth lens, and the effective focal length f6 of the sixth lens, the air gap T56 between the fifth and sixth lenses on the optical axis of the optical camera lens, the maximum thickness CP5 of the fifth bearing member, and the inner diameter d5m of the image side surface of the fifth bearing member satisfy the following: -3.4 < f6*(T56 / CP5) / d5m < -0.5. This application provides a seven-element optical camera lens with a half field of view greater than 100°. Since ultra-wide-angle optical camera lenses are prone to internal reflection stray light, this application reduces the generation of stray light by setting multiple support members. At the same time, by controlling the spacing between the fifth and sixth lenses, the effective focal length of the sixth lens, and the thickness and inner diameter of the fifth support member, the light incident on the sixth and seventh lenses can be reasonably controlled, thereby reducing the generation of stray light.

[0006] According to another aspect of the present invention, an optical camera lens is provided, comprising: seven lenses, the seven lenses being sequentially arranged from the object side to the image side of the optical camera lens, including a first lens to a seventh lens; a plurality of bearing members, at least including a second bearing member located on the image side of a second lens and at least partially in contact with the image side surface of the second lens; a lens barrel for accommodating the lenses and the bearing members; wherein the half field of view of the optical camera lens is greater than 100°; the effective focal length f3 of the third lens, the outer diameter D2s of the object side surface of the second bearing member, the inner diameter d2s of the object side surface of the second bearing member, and the effective focal length f2 of the second lens satisfy the following: -17.0mm < f3*(D2s-d2s) / f2 < -9.8mm. This application provides a seven-element optical camera lens with a half field of view greater than 100°. Since ultra-wide-angle optical camera lenses are prone to internal reflection stray light, this application reduces the generation of stray light by setting multiple support members. At the same time, by controlling the effective focal length of the second and third lenses and the inner and outer diameters of the second support member, it can intercept stray light at the lens edge.

[0007] According to another aspect of the present invention, an optical camera lens is provided, comprising: seven lenses, the seven lenses being sequentially arranged from the object side to the image side of the optical camera lens as a first lens to a seventh lens; a plurality of bearing members, at least one of the bearing members being a second bearing member located on the image side of a second lens and at least partially in contact with the image side surface of the second lens; a lens barrel for accommodating the lenses and the bearing members; wherein the half field of view of the optical camera lens is greater than 100°; at least one of the plurality of bearing members is located on the image side of a fourth lens and at least partially in contact with the image side surface of the fourth lens.

This application provides a seven-element optical camera lens with a half-field of view greater than 100°. Since ultra-wide-angle optical cameras are prone to internal reflection stray light, this application, by setting multiple support members, helps to reduce the generation of stray light. Simultaneously, by controlling the effective focal length, radius of curvature, center thickness, and spacing between the fourth and fifth lenses, the processability and light adjustment capabilities of the fourth and fifth lenses can be effectively improved, and stray light generation can be reduced.

[0015] Furthermore, among the multiple supporting components, there is at least a fourth supporting component located 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 supporting component located on the image side of the fifth lens and in at least partial contact with the image side surface of the fifth lens. The radius of curvature R8 of the image side surface of the fourth lens, the interval EP45 between the fourth supporting component and the fifth supporting component, the center thickness CT5 of the fifth lens on the optical axis of the optical camera lens, the radius of curvature R9 of the object side surface of the fifth lens, and the effective focal length f5 of the fifth lens satisfy the following: -0.75 < R8*(EP45+CT5) / (R9*f5) < -0.35.

[0016] Furthermore, among the multiple supporting components, there is at least a fifth supporting component located on the image side of the fifth lens and in at least partial contact with the image side surface of the fifth lens, and a sixth supporting component located on the image side of the sixth lens and in at least partial contact with the image side surface of the sixth lens.

[0022] This application provides a seven-element optical camera lens with a half field of view greater than 100°. Since ultra-wide-angle optical camera lenses are prone to internal reflection stray light, this application reduces the generation of stray light by setting multiple support members. At the same time, by controlling the front lens and the support members between the lenses, especially the radius of curvature of the second lens and the inner diameter of the second support member, the stray light generated by the edge light hitting the structural area can be constrained to a certain extent, and the stray light is intercepted, effectively reducing the edge stray light.

[0042] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0043] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0044] In this invention, unless otherwise stated, directional terms such as "upper," "lower," "top," and "bottom" are generally used in relation to the direction shown in the accompanying drawings, or in relation to the vertical, perpendicular, or gravitational direction of the component itself; similarly, for ease of understanding and description, "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not intended to limit this invention.

[0045] It should be noted that in this specification, the terms "first," "second," "third," etc., are used only to distinguish one feature from another and do not imply any limitation on the features. Therefore, without departing from the teachings of this application, the first lens discussed below may also be referred to as the second lens or the third lens.

[0046] In the accompanying drawings, the thickness, size, and shape of the lenses have been slightly exaggerated for ease of illustration. Specifically, the shapes of the spherical or aspherical surfaces shown in the drawings are illustrated by way of example. That is, the shapes of the spherical or aspherical surfaces are not limited to those shown in the drawings. The drawings are for illustrative purposes only and are not drawn strictly to scale.

[0047] In this paper, the paraxial region refers to the region near the optical axis. If the lens surface is convex and the location of that convexity is not defined, it means that the lens surface is convex at least in the paraxial region; if the lens surface is concave and the location of that concaveness is not defined, it means that the lens surface is concave at least in the paraxial region. The determination of the surface shape in the paraxial region can be based on the judgment method commonly used by those knowledgeable in the field, using the R value (R refers to the radius of curvature of the paraxial region, usually the R value in the lens data in optical software) to determine convexity or concavity. For the object side, a positive R value indicates a convex surface, and a negative R value indicates a concave surface; for the image side, a positive R value indicates a concave surface, and a negative R value indicates a convex surface.

[0048] To address the problem of severe stray light in existing optical camera lenses, this invention provides an optical camera lens.

[0049] First Implementation Method

[0050] like Figures 1 to 19As shown, the optical camera lens includes seven lenses, multiple support members, and a lens barrel P0. The seven lenses, from the object side to the image side of the optical camera lens, include a first lens to a seventh lens in sequence. Among the multiple support members, at least one is a second support member located on the image side of the second lens and in at least partial contact with the image side surface of the second lens. The lens barrel P0 is used to accommodate the lenses and the support members. The half field of view of the optical camera lens is greater than 100°. The radius of curvature R3 of the object side surface of the second lens, the radius of curvature R4 of the image side surface of the second lens, and the inner diameter d2s of the object side surface of the second support member satisfy the following condition: -2.8 < (R3 + R4) / d2s < -0.35.

[0051] This application provides a seven-element optical camera lens with a half-field of view greater than 100°. Since ultra-wide-angle optical cameras are prone to internal stray light, this application, by setting multiple support members, helps to reduce stray light generation. Simultaneously, by controlling the front lens and the support members between the lenses, especially the radius of curvature of the second lens and the inner diameter of the second support member, it can, to a certain extent, constrain stray light generated by edge rays hitting the structural area, and intercept stray light, effectively reducing edge stray light. Figure 2 A schematic diagram of the stray light optical path of an optional embodiment of this application is shown. Figure 19 As shown, this application, through the setting of the bearing component, can achieve a higher level of stability than... Figure 20 The existing technology shown has less stray light energy.

[0052] This application also controls the curvature radius of the object side and image side of the second lens to prevent the second lens from being too curved, which helps to reduce the difficulty of lens processing and forming. At the same time, it enables the optical camera lens to have a better ability to balance chromatic aberration and distortion, thereby improving the image quality.

[0053] Preferably, the radius of curvature R3 of the object side of the second lens, the radius of curvature R4 of the image side of the second lens, and the inner diameter d2s of the object side of the second support member satisfy the following: -2.790 < (R3 + R4) / d2s < -0.355.

[0054] In this embodiment, the outer diameter D0s of the object-side end face of the lens barrel P0, the outer diameter D0m of the image-side end face of the lens barrel P0, and the effective focal length f of the optical camera lens satisfy the following relationship: 1.6 < (D0s - D0m) / f < 2.7. By limiting (D0s - D0m) / f within a reasonable range, the outer diameters of the object-side and image-side end faces of the lens barrel P0 can be reasonably controlled, effectively controlling the overall diameter of the lens barrel P0 and preventing structural interference when it is fitted with the module. Simultaneously, by reasonably controlling the effective focal length of the optical camera lens, the distance between the image plane and the lens can be directly controlled, ensuring that the module length remains within the design range. Preferably, 1.605 < (D0s - D0m) / f < 2.695.

[0055] In this embodiment, the effective focal length f1 of the first lens, the inner diameter d0s of the object-side end face of the lens barrel P0, the outer diameter D2s of the object-side side face of the second support member, and the effective focal length f2 of the second lens satisfy the following condition: 2.7 ≤ f1*(d0s / D2s) / f2 < 4.3. By limiting f1*(d0s / D2s) / f2 within a reasonable range, the effective focal lengths of the first and second lenses are controlled, which can effectively adjust the spherical aberration range of the lens and thus balance the spherical aberration generated by other lens groups. Simultaneously, a reasonable design of the outer diameter of the second support member can effectively control the annular area of ​​the second support member, making it less prone to deformation and improving assembly stability and consistency. Preferably,

[0056] In this embodiment, the combined focal length f12 of the first and second lenses, the air gap T12 between the first and second lenses on the optical axis of the lens, the air gap T23 between the second and third lenses on the optical axis, the maximum thickness CP2 of the second support member, and the inner diameter d2s of the object side of the second support member satisfy the following condition: -1.9mm < f12*(T12+T23+CP2) / d2s < -1.3mm. By limiting f12*(T12+T23+CP2) / d2s within a reasonable range, controlling the combined focal length of the first and second lenses and the corresponding air gap allows for reasonable control of the contribution range of optical power and the contribution rate of negative spherical aberration. Simultaneously, controlling the inner diameter of the second support member allows for reasonable blocking of invalid edge light rays, improving image quality. Preferably, -1.855mm < f12*(T12+T23+CP2) / d2s < -1.305mm.

[0057] In this embodiment, the plurality of supporting members includes at least a fourth supporting member located on the image side of the fourth lens and in at least partial contact with the image side of the fourth lens. The effective focal length f4 of the fourth lens, the inner diameter d4s of the object side of the fourth supporting member, the effective focal length f5 of the fifth lens, and the inner diameter d4m of the image side of the fourth supporting member satisfy the following condition: 2.0 < f4 / d4s + f5 / d4m < 2.9. By limiting f4 / d4s + f5 / d4m within a reasonable range, and by reasonably allocating the effective focal lengths of the fourth and fifth lenses, the optical power of the middle section of the system is controlled within a small range, which can reduce the deflection angle of light and effectively reduce the system sensitivity. At the same time, by controlling the inner diameter of the fourth supporting member, a reasonable amount of light can be obtained, achieving the brightness required by the design. Preferably, 2.05 < f4 / d4s + f5 / d4m < 2.85.

[0058] In this embodiment, the plurality of supporting members includes at least a fifth supporting member located on the image side of the fifth lens and in at least partial contact with the image side surface of the fifth lens. The effective focal length f6 of the sixth lens, the air gap T56 between the fifth and sixth lenses on the optical axis of the camera lens, the maximum thickness CP5 of the fifth supporting member, and the inner diameter d5m of the image side surface of the fifth supporting member satisfy the following condition: -3.4 < f6*(T56 / CP5) / d5m < -0.5. By limiting f6*(T56 / CP5) / d5m within a reasonable range, and by controlling the effective focal length of the sixth lens and the aforementioned air gap, the light at this location can be effectively diffused appropriately, thereby obtaining the image plane size required by the design. At the same time, by controlling the inner diameter and thickness of the fifth supporting member, the light incident on the sixth and seventh lenses can be reasonably controlled, reducing the generation of stray light. Preferably, -3.380 < f6*(T56 / CP5) / d5m < -0.505.

[0059] In this embodiment, the effective focal length f3 of the third lens, the outer diameter D2s of the object-side surface of the second support member, the inner diameter d2s of the object-side surface of the second support member, and the effective focal length f2 of the second lens satisfy the following condition: -17.0mm < f3*(D2s-d2s) / f2 < -9.8mm. By limiting f3*(D2s-d2s) / f2 within a reasonable range, the effective focal lengths of the second and third lenses are controlled, which balances the overall field curvature of the lens. Simultaneously, by coordinating the inner and outer diameters of the second support member, the assembly step difference can be controlled within a reasonable range, and the annular area of ​​the second support member can be controlled, which is beneficial for improving assembly stability. Preferably, -16.95mm < f3*(D2s-d2s) / f2 < -9.85mm.

[0060] In this embodiment, the radius of curvature R6 of the image-side surface of the third lens, the radius of curvature R5 of the object-side surface of the third lens, and the inner diameter d2m of the image-side surface of the second support member satisfy the following condition: 1.6 < (R6 - R5) / d2m < 2.7. By limiting (R6 - R5) / d2m within a reasonable range, the radius of curvature of the third lens is controlled, which is beneficial for lens processing and shaping. Simultaneously, it effectively controls the degree of light convergence, improving system brightness. Furthermore, controlling the inner diameter of the second support member effectively absorbs stray light, improving image quality. Preferably, 1.63 < (R6 - R5) / d2m < 2.69.

[0061] In this embodiment, the plurality of supporting components includes at least a fourth supporting component located on the image side of the fourth lens and in at least partial contact with the image side of the fourth lens, and a fifth supporting component located on the image side of the fifth lens and in at least partial contact with the image side of the fifth lens. The radius of curvature R8 of the image side of the fourth lens, the interval EP45 between the fourth and fifth supporting components, the center thickness CT5 of the fifth lens on the optical axis of the optical camera lens, the radius of curvature R9 of the object side of the fifth lens, and the effective focal length f5 of the fifth lens satisfy the following condition: -0.75 < R8*(EP45+CT5) / (R9*f5) < -0.35. By limiting R8*(EP45+CT5) / (R9*f5) within a reasonable range, the manufacturability and light adjustment capability of the fourth and fifth lenses can be effectively improved. At the same time, in conjunction with the center thickness and interval parameters of the lenses, the distance between the various components on the optical axis can be effectively controlled, thereby effectively controlling the overall length of the lens. Preferably, -0.74 < R8*(EP45+CT5) / (R9*f5) < -0.36.

[0062] In this embodiment, the plurality of bearing members include at least a fifth bearing member located on the image side of the fifth lens and in at least partial contact with the image side surface of the fifth lens, and a sixth bearing member located on the image side of the sixth lens and in at least partial contact with the image side surface of the sixth lens. The effective focal length f6 of the sixth lens, the interval EP56 between the fifth bearing member and the sixth bearing member, the effective focal length f7 of the seventh lens, the maximum thickness CP6 of the sixth bearing member, the center thickness CT6 of the sixth lens on the optical axis of the optical camera lens, and the center thickness CT7 of the seventh lens on the optical axis satisfy the following: 2.0 < |f6*EP56+f7*CP6| / (CT6*CT7) < 9.0. By limiting |f6*EP56+f7*CP6| / (CT6*CT7) within a reasonable range, the effective focal lengths of the sixth and seventh lenses can be controlled, thus controlling the system's astigmatism. Simultaneously, by coordinating the thickness of the seventh lens with the spacing between the fifth and sixth support members, the edge thickness of the two lenses can be reasonably controlled, thereby obtaining the lens thickness ratio parameters within the design requirements. Preferably, 2.2 < |f6*EP56+f7*CP6| / (CT6*CT7) < 8.9.

[0063] In this embodiment, the plurality of supporting members includes at least a fourth supporting member located on the image side of the fourth lens and in at least partial contact with the image side of the fourth lens. The effective focal length f4 of the fourth lens, the Abbe number V4 of the fourth lens, the outer diameter D4s of the object side of the fourth supporting member, and the inner diameter d4s of the object side of the fourth supporting member satisfy the following condition: 21.0 < f4*V4 / (D4s+d4s) < 35.5. By limiting f4*V4 / (D4s+d4s) within a reasonable range, controlling the effective focal length and Abbe number of the fourth lens allows for reasonable control of the light transmission of the fourth lens, improving overall illuminance. Simultaneously, controlling the inner and outer diameters of the fourth supporting member allows for the acquisition of a reasonable annular area, which can absorb stray light while reducing the risk of deformation. Preferably, 21.05 < f4*V4 / (D4s+d4s) < 35.4.

[0064] In this embodiment, the plurality of supporting members includes at least a sixth supporting member located on the image side of the sixth lens and in at least partial contact with the image side of the sixth lens. The effective focal length f7 of the seventh lens, the outer diameter D6m of the image side of the sixth supporting member, the effective focal length f6 of the sixth lens, and the outer diameter D6s of the object side of the sixth supporting member satisfy the following condition: 1.1 < f7*D6m / (f6*D6s) < 2.9. By limiting f7*D6m / (f6*D6s) within a reasonable range, the effective focal lengths of the sixth and seventh lenses are controlled, which can better connect the incident light angles and obtain a reasonable overall focal length, so that the module chip is positioned in a reasonable design position. At the same time, controlling the outer diameters on both sides of the sixth supporting member obtains a better supporting gradient, thus ensuring assembly stability. Preferably, 1.15 < f7*D6m / (f6*D6s) < 2.85.

[0065] In this embodiment, two of the seven lenses are glass lenses, and five are plastic lenses. This arrangement allows the optical camera lens to receive incident light at a wider angle, resulting in a broader "field of view" and thus meeting more application scenarios. At the same time, the hardness of the glass lenses effectively prevents many cosmetic scratches, making the lens more versatile in its operating conditions. Combined with a reasonable inter-lens support design, the lens maintains both good stability and a high level of image quality.

[0066] In this embodiment, the first lens and the fourth lens are spherical glass lenses to prevent scratches on the lens surface from affecting the imaging.

[0067] Second Implementation Method

[0068] like Figures 1 to 19As shown, the optical camera lens includes seven lenses, multiple support members, and a lens barrel P0. The seven lenses, from the object side to the image side of the optical camera lens, include a first lens to a seventh lens in sequence. Among the multiple support members, there is at least a second support member located on the image side of the second lens and in at least partial contact with the image side surface of the second lens. The lens barrel P0 is used to accommodate the lenses and the support members. The half field of view of the optical camera lens is greater than 100°. Among the multiple support members, there is at least a fifth support member located on the image side of the fifth lens and in at least partial contact with the image side surface of the fifth lens. The effective focal length f6 of the sixth lens, the air gap T56 between the fifth and sixth lenses on the optical axis of the optical camera lens, the maximum thickness CP5 of the fifth support member, and the inner diameter d5m of the image side surface of the fifth support member satisfy the following condition: -3.4 < f6*(T56 / CP5) / d5m < -0.5.

[0069] This application provides a seven-element optical camera lens with a half-field of view greater than 100°. Since ultra-wide-angle optical camera lenses are prone to internal stray light, this application, by setting multiple support members, helps to reduce the generation of stray light. Simultaneously, by controlling the spacing between the fifth and sixth lenses, the effective focal length of the sixth lens, and the thickness and inner diameter of the fifth support member, the light incident on the sixth and seventh lenses can be reasonably controlled, further reducing stray light generation. Figure 2 A schematic diagram of the stray light optical path of an optional embodiment of this application is shown. Figure 19 As shown, this application, through the setting of the bearing component, can achieve a higher level of stability than... Figure 20 The existing technology shown has less stray light energy.

[0070] This application can also effectively diffuse the light at the sixth lens appropriately through the above control, thereby obtaining the image plane size required by the design.

[0071] Preferably, the effective focal length f6 of the sixth lens, the air gap T56 between the fifth and sixth lenses on the optical axis of the optical camera lens, the maximum thickness CP5 of the fifth support member, and the inner diameter d5m of the image side of the fifth support member satisfy the following condition: -3.380 < f6*(T56 / CP5) / d5m < -0.505.

[0072] This embodiment may also include other parametric expressions from the first embodiment, which will not be elaborated here.

[0073] Third Implementation Method

[0074] like Figures 1 to 19As shown, the optical camera lens includes seven lenses, multiple support members, and a lens barrel P0. The seven lenses, from the object side to the image side of the optical camera lens, include a first lens to a seventh lens in sequence. Among the multiple support members, at least one second support member is located on the image side of the second lens and is at least partially in contact with the image side surface of the second lens. The lens barrel P0 is used to accommodate the lenses and the support members. The half field of view of the optical camera lens is greater than 100°. The effective focal length f3 of the third lens, the outer diameter D2s of the object side surface of the second support member, the inner diameter d2s of the object side surface of the second support member, and the effective focal length f2 of the second lens satisfy the following condition: -17.0mm < f3*(D2s-d2s) / f2 < -9.8mm.

[0075] This application provides a seven-element optical camera lens with a half-field of view greater than 100°. Since ultra-wide-angle optical cameras are prone to internal stray light, this application, by setting multiple support members, helps to reduce stray light generation. Simultaneously, by controlling the effective focal length of the second and third lenses and the inner and outer diameters of the second support member, it can intercept stray light from the lens edges. Figure 2 A schematic diagram of the stray light optical path of an optional embodiment of this application is shown. Figure 19 As shown, this application, through the setting of the bearing component, can achieve a higher level of stability than... Figure 20 The existing technology shown has less stray light energy.

[0076] This application can also balance the overall field curvature of the lens, while controlling the ring area of ​​the second support component, and controlling the assembly step difference within a reasonable range, which is conducive to improving assembly stability.

[0077] Preferably, the effective focal length f3 of the third lens, the outer diameter D2s of the object side of the second support member, the inner diameter d2s of the object side of the second support member, and the effective focal length f2 of the second lens satisfy the following: -16.95mm < f3*(D2s-d2s) / f2 < -9.85mm.

[0078] This embodiment may also include other parametric expressions from the first embodiment, which will not be elaborated here.

[0079] Fourth Implementation Method

[0080] like Figures 1 to 19As shown, the optical camera lens includes seven lenses, multiple support members, and a lens barrel P0. The seven lenses, from the object side to the image side, sequentially include a first lens to a seventh lens. At least one of the multiple support members is located on the image side of a second lens and is at least partially in contact with the image side surface of the second lens. The lens barrel P0 is used to house the lenses and the support members. The optical camera lens has a half-field of view greater than 100°. At least one of the multiple support members is located on the image side of a fourth lens and is at least partially in contact with the image side surface of the fourth lens. The fourth support member in partial contact, the fifth support member located on the image side of the fifth lens and in at least partial contact with the image side surface of the fifth lens, the radius of curvature R8 of the image side surface of the fourth lens, the interval EP45 between the fourth support member and the fifth support member, the center thickness CT5 of the fifth lens on the optical axis of the optical camera lens, the radius of curvature R9 of the object side surface of the fifth lens, and the effective focal length f5 of the fifth lens satisfy the following: -0.75<R8*(EP45+CT5) / (R9*f5)<-0.35.

[0081] This application provides a seven-element optical camera lens with a half-field of view greater than 100°. Since ultra-wide-angle optical camera lenses are prone to internal stray light, this application, by setting multiple support members, helps to reduce stray light generation. Simultaneously, by controlling the effective focal length, radius of curvature, center thickness of the fourth and fifth lenses, as well as the spacing between the fourth and fifth support members, the processability and light adjustment capabilities of the fourth and fifth lenses can be effectively improved, reducing stray light generation. Figure 2 A schematic diagram of the stray light optical path of an optional embodiment of this application is shown. Figure 19 As shown, this application, through the setting of the bearing component, can achieve a higher level of stability than... Figure 20 The existing technology shown has less stray light energy.

[0082] This application also allows for effective control of the distance between various components on the optical axis, thereby effectively controlling the overall length of the lens.

[0083] Preferably, the radius of curvature R8 of the image side of the fourth lens, the interval EP45 between the fourth and fifth support members, the center thickness CT5 of the fifth lens on the optical axis of the optical camera lens, the radius of curvature R9 of the object side of the fifth lens, and the effective focal length f5 of the fifth lens satisfy the following: -0.74 < R8*(EP45+CT5) / (R9*f5) < -0.36.

[0084] This embodiment may also include other parametric expressions from the first embodiment, which will not be elaborated here.

[0085] Optionally, the aforementioned optical camera lens may also include a filter for correcting color deviation and / or a protective glass for protecting the photosensitive element located on the imaging surface.

[0086] The optical camera lens in this application can employ multiple lenses, such as the seven lenses mentioned above. By rationally allocating the effective focal length, surface shape, center thickness of each lens, and on-axis distance between each lens, the aperture of the optical camera lens can be effectively increased, the sensitivity of the lens can be reduced, and the manufacturability of the lens can be improved, making the optical camera lens more conducive to production and processing and suitable for portable electronic devices such as smartphones.

[0087] In this application, at least one lens has an aspherical mirror surface. An aspherical lens is characterized by a continuously changing curvature from its center to its periphery. Unlike a spherical lens, which has a constant curvature from its center to its periphery, an aspherical lens has superior curvature radius characteristics, offering advantages in reducing distortion and astigmatism. By using an aspherical lens, aberrations occurring during image formation can be eliminated as much as possible, thereby improving image quality.

[0088] However, those skilled in the art will understand that the number of lenses constituting the optical camera lens can be changed to obtain the various results and advantages described herein without departing from the technical solutions claimed in this application. For example, although seven lenses are described as an example in the embodiments, the optical camera lens is not limited to including seven lenses. If necessary, the optical camera lens may also include other numbers of lenses.

[0089] Figure 1 A schematic diagram of the structure of an optical camera lens of this application is shown. Figure 1 The diagram also indicates parameters such as d2s, D6S, and d2m to clearly and intuitively explain their meaning. To better illustrate the optical camera lens structure and specific surface shapes, these parameters will not be shown in the accompanying diagrams when explaining specific examples.

[0090] Where Dis refers to the outer diameter of the object-side surface of the i-th bearing member, dis refers to the inner diameter of the object-side surface of the i-th bearing member, Dim refers to the outer diameter of the image-side surface of the i-th bearing member, and dim refers to the inner diameter of the image-side surface of the i-th bearing member, where i is a value from 1, 2, 3, 4, 5, and 6. EPij refers to the distance along the optical axis between the image-side surface of the i-th bearing member and the object-side surface of the j-th bearing member, where j > i, and i is a value from 1, 2, 3, 4, and 5, while j is a value from 2, 3, 4, 5, and 6. d0s is the inner diameter of the object-side end face of the lens barrel P0, and d0m is the inner diameter of the image-side end face of the lens barrel P0. The object-side end face of the lens barrel P0 is the surface of the lens barrel P0 closest to the object side, and the image-side end face of the lens barrel P0 is the surface of the lens barrel P0 closest to the image side.

[0091] The following description, with reference to the accompanying drawings, further illustrates examples of specific surface shapes and parameters of optical camera lenses applicable to the above embodiments.

[0092] It should be noted that any one of the following embodiments, from Embodiment 1 to Embodiment 8, is applicable to all implementation methods of this application.

[0093] Example 1

[0094] like Figures 3 to 5 The image shows an optical camera lens according to Embodiment 1 of this application.

[0095] like Figure 3 As shown, the optical camera lens, from the object side to the image side, includes, in sequence, a first lens E1, a second lens E2, a second support P2, a third lens E3, a fourth lens E4, a fourth support P4, a fifth lens E5, a fifth support P5, a sixth lens E6, a sixth support P6, and a seventh lens E7. The first lens E1 and the second lens E2 directly support each other. A support protrusion 10 is formed on the inner wall of the lens barrel P0 facing the optical axis, so that the image side of the third lens E3 and the object side of the fourth lens E4 rest on the support protrusion 10, thus enabling the support protrusion 10 to function as a support.

[0096] like Figure 3 As shown, the object-side surface of the first lens is S1, the image-side surface of the first lens is S2, the object-side surface of the second lens is S3, the image-side surface of the second lens is S4, the object-side surface of the third lens is S5, the image-side surface of the third lens is S6, the object-side surface of the fourth lens is S7, the image-side surface of the fourth lens is S8, the object-side surface of the fifth lens is S9, the image-side surface of the fifth lens is S10, the object-side surface of the sixth lens is S11, the image-side surface of the sixth lens is S12, the object-side surface of the seventh lens is S13, and the image-side surface of the seventh lens is S14.

[0100] Table 1 also shows the object side surface S15, the image side surface S16, and the imaging surface S17 of the filter.

[0101] In this embodiment, the first and fourth lenses are spherical lenses, while the object-side and image-side surfaces of the remaining lenses are aspherical. The surface shape of each aspherical lens can be defined using, but is not limited to, the following aspherical formula:

[0102]

[0103] Where x is the distance vector from the vertex of the aspherical surface at a height h along the optical axis; c is the paraxial curvature of the aspherical surface, c = 1 / R, that is, the paraxial curvature c is the reciprocal of the radius of curvature R in Table 1 above; k is the conic coefficient; Ai is the i-th order correction coefficient of the aspherical surface. Table 2 below gives the higher-order coefficients A4, A6, A8, A10, A12, A14, A16, A18, A20, A22, A24, A26, A28, A30 that can be used for each aspherical mirror in this embodiment.

[0105] Table 2

[0106] Figure 4 The on-axis chromatic aberration curve of the optical camera lens of Embodiment 1 is shown, which represents the deflection of the focal point of light of different wavelengths after passing through the optical camera lens. Figure 5 The astigmatism curve of the optical camera lens of Embodiment 1 is shown, which represents the meridional image plane curvature and the sagittal image plane curvature.

[0107] according to Figure 4 and Figure 5 As can be seen, the optical camera lens given in Example 1 can achieve good imaging quality.

[0108] Example 2

[0109] The difference from Embodiment 1 is that the parameters of the lens barrel P0 and the support component are different.

[0110] like Figure 6 The image shows an optical camera lens according to Embodiment 2 of this application. For the sake of brevity, descriptions similar to those in Embodiment 1 are omitted.

[0111] In Embodiment 2, the curvature radius, center thickness, and other parameters of the first to seventh lenses of the optical camera lens are the same as those in Embodiment 1, as are the inter-lens spacing and higher-order image coefficients, as shown in Tables 1 and 2. However, the parameters of the lens barrel P0, the thickness of the bearing member, the inner diameter and outer diameter of the bearing member, and the distance between the bearing members are different. In other words, the main structure used for imaging is the same, but the auxiliary structures used for imaging are different. Therefore, the imaging quality of the optical camera lens in this embodiment is as follows: Figure 4 and Figure 5 As shown.

[0112] like Figure 6 As shown, a fourth auxiliary support member P4b is also included between the fourth lens E4 and the fifth lens E5, and the fourth auxiliary support member P4b abuts against the image side of the fourth support member P4. This improves the abutment stability between the widely spaced fourth lens E4 and fifth lens E5, while also enhancing the interception effect on stray light.

[0113] Example 3

[0114] The difference from Embodiment 1 is that the parameters of the lens barrel P0, the support member, and the lens are different.

[0115] like Figures 7 to 9 The image shows an optical camera lens according to Embodiment 3 of this application. For the sake of brevity, descriptions similar to those in Embodiment 1 are omitted.

[0116] like Figure 7 As shown, the optical camera lens, from the object side to the image side, includes, in sequence, a first lens E1, a second lens E2, a second support P2, a third lens E3, a third support P3, a fourth lens E4, a fourth support P4, a fifth lens E5, a fifth support P5, a sixth lens E6, a sixth support P6, and a seventh lens E7. The first lens E1 and the second lens E2 directly support each other, and the lens structure has sufficient support area to ensure support stability.

[0117] Table 3 shows the basic structural parameters of the optical camera lens in Embodiment 3, where the units for radius of curvature, thickness / distance, and effective focal length are all millimeters (mm).

[0120] Table 3

[0121] Table 3 also shows the object side surface S15, the image side surface S16, and the imaging surface S17 of the filter.

[0122] In this embodiment, the first lens and the fourth lens are spherical lenses, and the object side and image side of the remaining lenses are aspherical.

[0124] Table 4

[0125] Figure 8 The on-axis chromatic aberration curve of the optical camera lens of Embodiment 3 is shown, which represents the deflection of the focal point of light of different wavelengths after passing through the optical camera lens. Figure 9 The astigmatism curve of the optical camera lens of Embodiment 3 is shown, which represents the meridional image plane curvature and the sagittal image plane curvature.

[0126] according to Figure 8 and Figure 9It can be seen that the optical camera lens given in Example 3 can achieve good imaging quality.

[0127] Example 4

[0128] The difference from Embodiment 3 is that the parameters of the lens barrel P0 and the support component are different.

[0129] like Figure 10 The image shows an optical camera lens according to Embodiment 4 of this application. For the sake of brevity, descriptions similar to those in Embodiment 1 are omitted.

[0130] The first to seventh lenses of the optical camera lens have the same parameters such as radius of curvature, center thickness, inter-lens spacing, and higher-order image coefficients, as shown in Tables 3 and 4. However, the parameters such as the lens barrel P0, the thickness of the bearing member, the inner diameter and outer diameter of the bearing member, and the distance between the bearing members are different. In other words, the main structure used for imaging is the same, but the auxiliary structures used for imaging are different. Therefore, the imaging quality of the optical camera lens in this embodiment is as follows: Figure 8 and Figure 9 As shown.

[0131] like Figure 10 As shown, there is no third support member P3 between the third lens E3 and the fourth lens E4. The inner wall of the lens barrel P0 has a support protrusion 10 facing the optical axis, so that the image side of the third lens E3 and the object side of the fourth lens E4 rest on the support protrusion 10, so that the support protrusion 10 acts as a support member.

[0132] Example 5

[0133] The difference from Embodiment 1 is that the parameters of the lens barrel P0, the support member, and the lens are different.

[0134] like Figures 11 to 13 The image shows an optical camera lens according to Embodiment 5 of this application. For the sake of brevity, descriptions similar to those in Embodiment 1 are omitted.

[0135] like Figure 11 As shown, the optical camera lens, from the object side to the image side, includes, in sequence, a first lens E1, a second lens E2, a second support P2, a third lens E3, a third support P3, a fourth lens E4, a fourth support P4, a fifth lens E5, a fifth support P5, a sixth lens E6, a sixth support P6, and a seventh lens E7. The first lens E1 and the second lens E2 directly support each other, and the lens structure has sufficient support area to ensure support stability.

[0136] Table 5 shows the basic structural parameters of the optical camera lens in Embodiment 5, where the units for radius of curvature, thickness / distance, and effective focal length are all millimeters (mm).

Table 6 gives the higher-order coefficients of each aspherical lens that can be used in this embodiment.

[0143] Table 6

[0144] Figure 12 The on-axis chromatic aberration curve of the optical camera lens of Embodiment 5 is shown, which represents the deflection of the focal point of light of different wavelengths after passing through the optical camera lens. Figure 13 The astigmatism curve of the optical camera lens of Embodiment 5 is shown, which represents the meridional image plane curvature and the sagittal image plane curvature.

[0145] according to Figure 12 and Figure 13 It can be seen that the optical camera lens given in Example 5 can achieve good imaging quality.

[0146] Example 6

[0147] The difference from Embodiment 5 is that the parameters of the lens barrel P0 and the support component are different.

[0148] like Figure 14 The image shows an optical camera lens according to Embodiment Six of this application. For the sake of brevity, descriptions similar to those in Embodiment One are omitted.

[0149] The first to seventh lenses of the optical camera lens have the same parameters such as radius of curvature, center thickness, inter-lens spacing, and higher-order image coefficients, as shown in Tables 5 and 6. However, the parameters such as the lens barrel P0, the thickness of the bearing member, the inner diameter and outer diameter of the bearing member, and the distance between the bearing members are different. In other words, the main structure used for imaging is the same, but the auxiliary structures used for imaging are different. Therefore, the imaging quality of the optical camera lens in this embodiment is as follows: Figure 12 and Figure 13 As shown.

[0150] like Figure 14As shown, a fourth auxiliary support member P4b is also included between the fourth lens E4 and the fifth lens E5, and the fourth auxiliary support member P4b abuts against the image side of the fourth support member P4. This improves the abutment stability between the widely spaced fourth lens E4 and fifth lens E5, while also enhancing the interception effect on stray light.

[0151] Example 7

[0152] The difference from Embodiment 1 is that the parameters of the lens barrel P0, the support member, and the lens are different.

[0153] like Figures 15 to 17 The image shows an optical camera lens according to Embodiment Seven of this application. For the sake of brevity, descriptions similar to those in Embodiment One are omitted.

[0154] like Figure 15 As shown, the optical camera lens, from the object side to the image side, includes, in sequence, a first lens E1, a second lens E2, a second support P2, a third lens E3, a third support P3, a fourth lens E4, a fourth support P4, a fourth auxiliary support P4b, a fifth lens E5, a fifth support P5, a sixth lens E6, a sixth support P6, and a seventh lens E7. The first lens E1 and the second lens E2 directly support each other, and the lens structure has sufficient support area to ensure support stability.
