Description

Technical Field

[0001] This application belongs to the field of optics, and particularly relates to a camera lens. Background Art

[0002] In recent years, with the development of science and technology, people's requirements for mobile phone lenses have become higher and higher, and mobile phone lenses with high imaging quality have been increasingly favored. However, due to the trend of portable electronic products towards miniaturization, the total length requirement for camera lenses has become increasingly strict, resulting in reduced design freedom and increased design difficulty. Generally speaking, the larger the pixel, the larger the image plane, making the volume of traditional-structured camera lenses also become larger and more difficult to match with thin and light electronic products such as mobile phones, restricting the popularization and application of camera lenses. However, when reducing the size of the camera lens, it is difficult to ensure the characteristics of a large image plane, resulting in the compression of the imaging quality of the camera lens and unable to meet the imaging needs of users. Therefore, how to meet the requirements of wide-angle and large image plane design under the condition of a small head, while obtaining high imaging quality and small aberration has also become a bottleneck that is difficult to break through.

[0039] The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0040] It should be noted that in this specification, the expressions such as first, second, and third are only used to distinguish one feature from another feature, and do not represent any limitation on the feature. Therefore, without departing from the teachings of the present application, the first lens discussed below may also be referred to as the second lens or the third lens.

[0041] It should also be understood that the terms "include", "include with", "have", "contain", and / or "contain with", when used in this specification, indicate the presence of the stated features, elements, and / or components, but do not exclude the presence or addition of one or more other features, elements, components, and / or their combinations. In addition, when an expression such as "at least one of......" appears after the list of listed features, it modifies the entire list of listed features, rather than modifying a single element in the list. In addition, when describing the embodiments of the present application, the use of "may" means "one or more embodiments of the present application". And the term "exemplary" is intended to refer to an example or illustration.

[0042] In the drawings, for the sake of convenience of explanation, the thickness, size, and shape of the lens have been slightly exaggerated. Specifically, the spherical or aspherical shapes shown in the drawings are shown by way of example. That is, the spherical or aspherical shapes are not limited to the spherical or aspherical shapes shown in the drawings. The drawings are only examples and are not drawn strictly to scale.

[0043] In the description of the present application, the paraxial region refers to the region near the optical axis. If the lens surface is convex and the position of the convex surface 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 position of the concave surface is not defined, it means that the lens surface is concave at least in the paraxial region. The surface of each lens closest to the object to be photographed is called the far light surface of the lens, and the surface of each lens closest to the imaging surface is called the near light surface of the lens.

[0044] Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. It should also be understood that terms (such as those defined in a common dictionary) should be interpreted as having a meaning consistent with their meaning in the context of the relevant art, and will not be interpreted in an idealized or overly formal manner unless expressly so defined herein.

[0045] It should be noted that, without conflict, the embodiments in this application and the features in the embodiments can be combined with each other. The features, principles, and other aspects of this application will be described in detail below with reference to the drawings and in combination with the embodiments.

[0046] Exemplary embodiments

[0047] The exemplary camera lens of this application includes: a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens, a seventh lens, an eighth lens, and a ninth lens. Among them, each lens is independent of each other, and there is an air gap between each lens on the optical axis.

[0048] In the exemplary embodiment of this application, the camera lens includes: a first lens with a positive focal power; a second lens with a negative focal power; a third lens with a positive focal power, whose object side is convex and whose image side is convex; a fourth lens with a positive focal power; a fifth lens with a focal power; a sixth lens with a positive focal power; a seventh lens with a focal power; an eighth lens with a positive focal power; a ninth lens with a negative focal power, whose object side is concave and whose image side is convex. In the embodiment of this application, the first lens has a positive focal power and can play a main converging role; the second lens has a negative focal power and can converge the light rays of a large field of view; the third lens has a positive focal power, the fourth lens has a positive focal power, the sixth lens has a positive focal power, the eighth lens has a positive focal power, and the ninth lens has a negative focal power, which is beneficial to meeting the design requirements of a wide angle and a large image plane.

[0049] In the exemplary embodiment of this application, half of the diagonal length ImgH of the effective pixel area on the imaging surface of the camera lens and the effective radius DT11 of the object side of the first lens satisfy: 2.5 < ImgH / DT11 < 3.5. By controlling the ratio of the effective radius of the object side of the first lens to the image height, it can be ensured that the system has a smaller head size and processability. More specifically, half of the diagonal length ImgH of the effective pixel area on the imaging surface of the camera lens and the effective radius DT11 of the object side of the first lens satisfy: 2.51 < ImgH / DT11 < 3.49.

[0050] In an exemplary embodiment of the present application, half of the diagonal length ImgH of the effective pixel region on the imaging surface of the camera lens satisfies: ImgH > 6 mm. By controlling this parameter within a certain range of conditions, it can be ensured that the size of the imaging surface is close to one inch, a larger chip can be applied, and better image quality can be obtained. More specifically, half of the diagonal length ImgH of the effective pixel region on the imaging surface of the camera lens satisfies: ImgH > 6.01 mm.

[0051] In an exemplary embodiment of the present application, the effective radius DT11 of the object side surface of the first lens and the effective radius DT91 of the object side surface of the ninth lens satisfy: 0.4 < DT11 / DT91 < 0.6. If the value of this conditional expression is too small, it will result in too small a head size and insufficient light input. If the value is too large, it will result in too large a head size and affect the external performance of the lens. Therefore, controlling this conditional expression within a reasonable range can ensure sufficient F-number and a smaller head size, thus ensuring the appearance performance. More specifically, the effective radius DT11 of the object side surface of the first lens and the effective radius DT91 of the object side surface of the ninth lens satisfy: 0.4 < DT11 / DT91 < 0.59.

[0052] In an exemplary embodiment of the present application, the axial distance SD from the aperture of the camera lens to the image side surface of the ninth lens, the maximum semi-field angle Semi-FOV of the camera lens, and the effective radius DT11 of the object side surface of the first lens satisfy: 2 < SD × TAN(Semi-FOV) / DT11 < 4. If the value of this conditional expression is too large, it will result in too small an aperture of the first lens and affect the light input. If it is too small, it will result in insufficient field angle. Therefore, by controlling this expression within a certain range, it can be ensured that there is a sufficiently large field angle and a large light input. More specifically, the axial distance SD from the aperture of the camera lens to the image side surface of the ninth lens, the maximum semi-field angle Semi-FOV of the camera lens, and the effective radius DT11 of the object side surface of the first lens satisfy: 2.01 < SD × TAN(Semi-FOV) / DT11 < 3.99.

[0053] In an exemplary embodiment of the present application, the aperture value Fno of the camera lens and the maximum semi-field angle Semi-FOV of the camera lens satisfy: 1 < Fno / TAN(Semi-FOV) < 3. If the value of this conditional expression is too large, it will result in a relatively small light input. If it is too small, it will be difficult to control the imaging quality. Therefore, by controlling this conditional expression within a certain range, it can be ensured that there is sufficient image quality and a large light input. More specifically, the aperture value Fno of the camera lens and the maximum semi-field angle Semi-FOV of the camera lens satisfy: 1.01 < Fno / TAN(Semi-FOV) < 2.99.

[0054] In an exemplary embodiment of the present application, the on-axis distance TTL from the object side surface of the first lens to the imaging surface of the camera lens, and the entrance pupil diameter EPD of the camera lens satisfy: 1 < TTL / EPD < 3. By controlling the ratio of TTL and EPD within a reasonable range, the size of the system is effectively compressed, ensuring the ultra-thin characteristic of the lens to meet the requirements of miniaturization of the imaging system. More specifically, the on-axis distance TTL from the object side surface of the first lens to the imaging surface of the camera lens, and the entrance pupil diameter EPD of the camera lens satisfy: 1.01 < TTL / EPD < 2.99.

[0055] In an exemplary embodiment of the present application, the effective focal length f4 of the fourth lens, the central thickness CT4 of the fourth lens, and the edge thickness ET4 of the fourth lens satisfy: 50 < f4 / (CT4 - ET4) < 101. By defining the numerical values of this conditional expression, the refraction of light by the fourth lens can be reasonably utilized to control the astigmatism of the system and improve the imaging quality of the off-axis field of view. More specifically, the effective focal length f4 of the fourth lens, the central thickness CT4 of the fourth lens, and the edge thickness ET4 of the fourth lens satisfy: 50.01 < f4 / (CT4 - ET4) < 100.99.

[0056] In an exemplary embodiment of the present application, the effective focal length f3 of the third lens, the curvature radius R5 of the object side surface of the third lens, and the curvature radius R6 of the image side surface of the third lens satisfy: -8 < f3 / (R5 + R6) < -2. Through the constraint of this conditional expression, the refraction of light by the third lens can be reasonably utilized. Therefore, controlling this conditional expression within a reasonable range is beneficial to better balance and achieve miniaturization of the module. More specifically, the effective focal length f3 of the third lens, the curvature radius R5 of the object side surface of the third lens, and the curvature radius R6 of the image side surface of the third lens satisfy: -7.99 < f3 / (R5 + R6) < -2.01.

[0057] In an exemplary embodiment of the present application, the effective focal length f of the camera lens, the effective focal length f1 of the first lens, and the effective focal length f2 of the second lens satisfy: -9 < f / (f1 + f2) < -6. If the numerical value of this conditional expression is too large, it will result in too large a focal length of the system, which will compress the designed field of view. If it is too small, it will result in too small a focal length of the system, resulting in insufficient image height. Therefore, controlling the numerical value of this conditional expression within a reasonable range can reasonably control the field of view and improve the pixels. More specifically, the effective focal length f of the camera lens, the effective focal length f1 of the first lens, and the effective focal length f2 of the second lens satisfy: -8.99 < f / (f1 + f2) < -6.01.

[0058] In an exemplary embodiment of the present application, the effective focal length f of the camera lens, the effective focal length f4 of the fourth lens, and the Abbe number V4 of the fourth lens satisfy: 10 < f / f4 × V4 < 20. If the value of this conditional expression is too small, it will cause insufficient diopter of the fourth lens, and if it is too large, it will cause insufficient field of view angle. Therefore, controlling this conditional expression within a reasonable range can ensure a sufficiently large image height and excellent imaging quality. More specifically, the effective focal length f of the camera lens, the effective focal length f4 of the fourth lens, and the Abbe number V4 of the fourth lens satisfy: 10.01 < f / f4 × V4 < 19.99.

[0059] In an exemplary embodiment of the present application, the effective focal length f9 of the ninth lens, the curvature radius R17 of the object side surface of the ninth lens, and the curvature radius R18 of the image side surface of the ninth lens satisfy: -50 < f9 / (R17 - R18) < -10. Through the constraint of this conditional expression, the deflection of light by the ninth lens can be reasonably utilized. Therefore, controlling this conditional expression within a reasonable range is beneficial to better balance and achieve miniaturization of the module. More specifically, the effective focal length f9 of the ninth lens, the curvature radius R17 of the object side surface of the ninth lens, and the curvature radius R18 of the image side surface of the ninth lens satisfy: -49.99 < f9 / (R17 - R18) < -10.01.

[0060] In an exemplary embodiment of the present application, the effective focal length f8 of the eighth lens, the effective focal length f9 of the ninth lens, and the air gap T89 between the eighth lens and the ninth lens on the optical axis satisfy: 45 < (f8 - f9) / T89 < 62. If the value of this conditional expression is too small, it will cause too large a gap between the eighth and ninth lenses and too long a system length, and if it is too large, it will cause too small a combined optical power of the eighth and ninth lenses and insufficient light convergence ability. Therefore, controlling this conditional expression within a reasonable range is beneficial to better balance and achieve miniaturization of the module. More specifically, the effective focal length f8 of the eighth lens, the effective focal length f9 of the ninth lens, and the air gap T89 between the eighth lens and the ninth lens on the optical axis satisfy: 45.01 < (f8 - f9) / T89 < 61.99.

[0061] In an exemplary embodiment of the present application, the curvature radius R11 of the object side surface of the sixth lens, and the curvature radius R12 of the image side surface of the sixth lens satisfy: 3 < (R11 + R12) / (R11 - R12) < 5. By controlling this conditional expression within a reasonable range, the incident angle of paraxial rays can be reduced, the outgoing rays can be converged, the effective focal length can be reduced, and the system convergence ability can be increased. More specifically, the curvature radius R11 of the object side surface of the sixth lens, and the curvature radius R12 of the image side surface of the sixth lens satisfy: 3.01 < (R11 + R12) / (R11 - R12) < 4.99.

[0062] In an exemplary embodiment of the present application, the central thickness CT1 of the first lens, the central thickness CT2 of the second lens, the central thickness CT3 of the third lens, the central thickness CT4 of the fourth lens, and the sum ∑CT of the central thicknesses of the first lens and the ninth lens satisfy: 0.5 < (CT1 + CT2 + CT3 + CT4) / ∑CT < 0.6. Controlling this conditional expression within a reasonable range is beneficial to better balance and achieve miniaturization of the module. More specifically, the central thickness CT1 of the first lens, the central thickness CT2 of the second lens, the central thickness CT3 of the third lens, the central thickness CT4 of the fourth lens, and the sum ∑CT of the central thicknesses of the first lens and the ninth lens satisfy: 0.51 < (CT1 + CT2 + CT3 + CT4) / ∑CT < 0.59.

[0063] In an exemplary embodiment of the present application, the maximum edge thickness ETMAX among the edge thicknesses of the first lens to the ninth lens, and the maximum central thickness CTMAX among the central thicknesses of the first lens to the ninth lens satisfy: 0.8 < ETMAX / CTMAX < 1.1. Controlling this conditional expression can improve the imaging ability as much as possible on the basis that the mold is easier to form. Therefore, by controlling the value of this conditional expression within a certain range, the processability can be improved. More specifically, the maximum edge thickness ETMAX among the edge thicknesses of the first lens to the ninth lens, and the maximum central thickness CTMAX among the central thicknesses of the first lens to the ninth lens satisfy: 0.81 < ETMAX / CTMAX < 1.09.

[0064] In this exemplary embodiment, both the far-light surface and the near-light surface of any one of the first lens E1 to the ninth lens E9 are aspherical surfaces. The surface shape x of each aspherical lens can be defined by, but not limited to, the following aspherical formula:

[0065]

[0066] where x is the sagitta, the distance from the vertex of the aspherical surface when the aspherical surface is along the optical axis at a position with a height of h; 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); k is the conic coefficient; and Ai is the correction coefficient of the i-th order of the aspherical surface.

[0067] In this exemplary embodiment, the above camera lens may further include a diaphragm. The diaphragm can be set at an appropriate position as needed. For example, the diaphragm can be set between the far light and the first lens. Optionally, the above camera lens may further include a filter for correcting color deviation and / or a protective glass for protecting the photosensitive element located on the imaging surface.

[0068] The camera lens according to the above-described embodiment of the present application may employ multiple lenses, such as the nine lenses described above. By reasonably distributing the optical power, surface shape, central thickness of each lens, and the on-axis distance between each lens, etc., the camera lens has a smaller size and volume, has a wide imaging range and high imaging quality, and ensures the ultra-thinness of the camera lens.

[0069] In an exemplary embodiment, at least one of the lens surfaces of each lens is an aspherical surface, that is, at least one of the surfaces from the far-light surface of the first lens to the near-light surface of the ninth lens is an aspherical surface. The characteristics of an aspherical lens are 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 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 as much as possible the aberration that appears during imaging, thereby improving the imaging quality. Optionally, at least one of the far-light surface and the near-light surface of each of the first lens, the second lens, the third lens, the fourth lens, the fifth lens, the sixth lens, the seventh lens, the eighth lens, and the ninth lens is an aspherical surface. Optionally, both the far-light surface and the near-light surface of each of the first lens, the second lens, the third lens, the fourth lens, the fifth lens, the sixth lens, the seventh lens, the eighth lens, and the ninth lens are aspherical surfaces.

[0070] However, those skilled in the art should understand that without departing from the technical solutions claimed in the present application, the number of lenses constituting the camera lens can be changed to obtain the various results and advantages described in this specification. For example, although the nine lenses are described as an example in the embodiment, the camera lens is not limited to including nine lenses. If necessary, the camera lens may also include other numbers of lenses.
