[0002] With the development of science and technology, wide-angle lenses, especially ultra-wide-angle lenses, fisheye lenses, etc., play an important role in more and more places, such as photography, security, measurement, projection, entertainment, automobiles, etc. The short focal field characteristics of the wide-angle lens will form a unique barrel distortion, which will bring a strong visual impact to the observer. Generally speaking, the photosensitive element of the optical system is either a CCD image sensor or a CMOS image sensor. With the advancement of semiconductor manufacturing technology, the pixel size of the image sensor is continuously reduced, the pixel of the optical system is higher and higher, and the image quality is also higher and higher.

[0038] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The present application will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.

[0039] The features, principles, and other aspects of the present application are described in detail below.

[0040] An optical camera lens according to the exemplary embodiments of the present application can include, in order from the object side to the image side along the optical axis, a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens, a seventh lens, an eighth lens, and a ninth lens; the first lens has negative refractive power; the second lens has positive refractive power; the third lens has positive refractive power; the fourth lens has positive refractive power or negative refractive power; the fifth lens has positive refractive power; the sixth lens has positive refractive power; the seventh lens has negative refractive power; the eighth lens has positive refractive power; and the ninth lens has negative refractive power.

[0041] In the exemplary embodiments, the optical camera lens according to the present application can satisfy: 1.5 < tan(Semi-FOV) x f / R18 < 2.5, where Semi-FOV is the maximum half field of view of the optical camera lens, f is the effective focal length of the optical camera lens, and R18 is the radius of curvature of the image side surface of the ninth lens.

[0042] In the exemplary embodiments, the optical camera lens according to the present application can satisfy: 24.0 < T56 / T23 < 27.0, where T56 is the air separation of the fifth lens and the sixth lens on the optical axis, and T23 is the air separation of the second lens and the third lens on the optical axis.

[0043] The optical camera lens according to the exemplary embodiments of the present application can include, in order from the object side to the image side along the optical axis, a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens, a seventh lens, an eighth lens, and a ninth lens; the first lens has negative refractive power; the second lens has positive refractive power; the third lens has positive refractive power; the fourth lens has positive refractive power or negative refractive power; the fifth lens has positive refractive power; the sixth lens has positive refractive power; the seventh lens has negative refractive power; the eighth lens has positive refractive power; and the ninth lens has negative refractive power. The optical camera lens satisfies 1.5 < tan(Semi-FOV) x f / R18 < 2.5, where Semi-FOV is a maximum half field of view of the optical camera lens, f is an effective focal length of the optical camera lens, and R18 is a radius of curvature of an image side surface of the ninth lens; and the optical camera lens satisfies 24.0 < T56 / T23 < 27.0, where T56 is an air gap of the fifth lens and the sixth lens on the optical axis, and T23 is an air gap of the second lens and the third lens on the optical axis. By reasonably distributing the positive and negative refractive powers of the lenses in the optical camera lens, the total length of the focal length of the optical camera lens can be shortened, the imaging quality can be improved, and wide-angle and large-image features can be achieved. If the value of tan(Semi-FOV) x f / R18 is too large, the radius of curvature R18 will be too small, which will affect the control of the field curvature. If the value of tan(Semi-FOV) x f / R18 is too small, the field of view and the image height will be insufficient. Controlling tan(Semi-FOV) x f / R18 within a reasonable range can ensure a sufficiently large field of view, a relatively large image height, and good field curvature. If the value of T56 / T23 is too large, the edge gap of the front end lens will be too small, which will affect the assembly. If the value of T56 / T23 is too small, the front end structure will be too long, which will affect the total length of the system. Controlling T56 / T23 within a reasonable range can reduce the length of the front lens structure and ensure that the size of the head of the lens is small.

[0044] In the exemplary embodiments, the optical camera lens according to the present application can satisfy -3.5 < R3 / R4 < -2.5, where R3 is a radius of curvature of an object side surface of the second lens, and R4 is a radius of curvature of an image side surface of the second lens. Satisfying -3.5 < R3 / R4 < -2.5 can ensure that the refractive power of the second lens is not too large, and the sensitivity of the second lens is reduced.

[0045] In the exemplary embodiments, the optical camera lens according to the present application can satisfy -3.5 < f2 / R4 - f3 / R5 < -2.5, where R4 is a radius of curvature of an image side surface of the second lens, R5 is a radius of curvature of an object side surface of the third lens, f2 is an effective focal length of the second lens, and f3 is an effective focal length of the third lens. Satisfying -3.5 < f2 / R4 - f3 / R5 < -2.5 can effectively control the astigmatism of the optical camera lens, and thus the imaging quality of the off-axis field can be improved.

[0046] In exemplary embodiments, the optical camera lens according to the present application can satisfy: 13.0 < R7 / SAG41 + R8 / SAG42 < 21.0, wherein R7 is the curvature radius of the object side surface of the fourth lens, R8 is the curvature radius of the image side surface of the fourth lens, SAG41 is the on-axis distance between the intersection of the object side surface of the fourth lens and the optical axis and the effective radius vertex of the object side surface of the fourth lens, and SAG42 is the on-axis distance between the intersection of the image side surface of the fourth lens and the optical axis and the effective radius vertex of the image side surface of the fourth lens. If the value of the condition formula is too large, the sagittal height of the fourth lens is too small, which can cause the curvature radius of the fourth lens to be too large and the refractive power to be weakened. Therefore, satisfying 13.0 < R7 / SAG41 + R8 / SAG42 < 21.0 controls the condition formula within a reasonable range, which is conducive to better balancing the refractive powers of the lenses.

[0047] In exemplary embodiments, the optical camera lens according to the present application can satisfy: 13.0 < R7 / SAG41 + R8 / SAG42 < 21.0, wherein R7 is the curvature radius of the object side surface of the fourth lens, R8 is the curvature radius of the image side surface of the fourth lens, SAG41 is the on-axis distance between the intersection of the object side surface of the fourth lens and the optical axis and the effective radius vertex of the object side surface of the fourth lens, and SAG42 is the on-axis distance between the intersection of the image side surface of the fourth lens and the optical axis and the effective radius vertex of the image side surface of the fourth lens. If the value of the condition formula is too large, the sagittal height of the fourth lens is too small, which can cause the curvature radius of the fourth lens to be too large and the refractive power to be weakened. Therefore, satisfying 13.0 < R7 / SAG41 + R8 / SAG42 < 21.0 controls the condition formula within a reasonable range, which is conducive to better balancing the refractive powers of the lenses.

[0048] In exemplary embodiments, the optical camera lens according to the present application can satisfy: 0 < f7 / SAG71 + SAG72 / T78 < 3.5, wherein f7 is the effective focal length of the seventh lens, T78 is the air gap of the seventh lens and the eighth lens on the optical axis, SAG71 is the on-axis distance between the intersection of the object side surface of the seventh lens and the optical axis and the effective radius vertex of the object side surface of the seventh lens, and SAG72 is the on-axis distance between the intersection of the image side surface of the seventh lens and the optical axis and the effective radius vertex of the image side surface of the seventh lens. If the value of the condition formula is too large, the assembly of the seventh lens and the eighth lens is difficult, and if the value is too small, the axial length of the two lenses is too large. Therefore, satisfying 0 < f7 / SAG71 + SAG72 / T78 < 3.5 controls the condition formula within a reasonable range, which is conducive to better balancing the realization of module miniaturization.

[0049] In exemplary embodiments, the optical camera lens according to the present application can satisfy: -3.0 < SAG91 / T89 + SAG92 / CT9 < 0, wherein CT9 is the center thickness of the ninth lens on the optical axis, T89 is the air gap of the eighth lens and the ninth lens on the optical axis, SAG91 is the on-axis distance between the intersection of the object side of the ninth lens and the optical axis and the effective radius vertex of the object side of the ninth lens, and SAG92 is the on-axis distance between the intersection of the image side of the ninth lens and the optical axis and the effective radius vertex of the image side of the ninth lens. If the value of the condition is too large, the middle thickness of the ninth lens is too small, the lens stability is prone to decline, and if the value is too small, the lens length is too long. Therefore, satisfying -3.0 < SAG91 / T89 + SAG92 / CT9 < 0 is conducive to better balancing the miniaturization of the module.

[0050] In exemplary embodiments, the optical camera lens according to the present application can satisfy: 7.0 < R15 / f8 - R16 / CT8 < 17.0, wherein R15 is the curvature radius of the object side of the eighth lens, R16 is the curvature radius of the image side of the eighth lens, f8 is the effective focal length of the eighth lens, and CT8 is the center thickness of the eighth lens on the optical axis. Satisfying 7.0 < R15 / f8 - R16 / CT8 < 17.0 can effectively control the deflection angle of the system light beam at the eighth lens, effectively reduce the sensitivity of the system, and achieve good processing characteristics.

[0051] In exemplary embodiments, the optical camera lens according to the present application can satisfy: -3.5 < |R13-R14| / f7 < -1.5, wherein R13 is the curvature radius of the object side of the seventh lens, R14 is the curvature radius of the image side of the seventh lens, and f7 is the effective focal length of the seventh lens. Satisfying -3.5 < |R13-R14| / f7 < -1.5 can effectively control the deflection angle of the system light beam at the seventh lens, effectively reduce the sensitivity of the system, and reduce aberration and ghost image intensity.

[0052] In exemplary embodiments, the optical camera lens according to the present application can satisfy: 2.5 < CT3 / CT7 < 3.5, wherein CT3 is the center thickness of the third lens on the optical axis, and CT7 is the center thickness of the seventh lens on the optical axis. Satisfying 2.5 < CT3 / CT7 < 3.5 controls the thickness ratio of the third lens and the seventh lens on the optical axis within a certain range, which can effectively compensate and balance each other and reduce the aberration of the entire system.

[0053] In exemplary embodiments, the optical camera lens according to the present application can satisfy: 5.5 < (SAG31+CT3) / (SAG11+CT1) < 24.5, wherein CT1 is the center thickness of the first lens on the optical axis, CT3 is the center thickness of the third lens on the optical axis, SAG11 is the on-axis distance between the intersection of the object side of the first lens and the optical axis and the effective radius vertex of the object side of the first lens, and SAG31 is the on-axis distance between the intersection of the object side of the third lens and the optical axis and the effective radius vertex of the object side of the third lens. A value of the condition formula that is too large results in a weak conditional ability of the first lens to incident light, and a value that is too small results in the first lens occupying too much space, affecting the design concept of the small head. Therefore, satisfying 5.5 < (SAG31+CT3) / (SAG11+CT1) < 24.5 helps to better balance the realization of module miniaturization.

[0054] In exemplary embodiments, the optical camera lens according to the present application can satisfy: 2.0 < R1 / f1+R17 / f9 < 3.0, wherein R1 is the curvature radius of the object side of the first lens, R17 is the curvature radius of the object side of the ninth lens, f1 is the effective focal length of the first lens, and f9 is the effective focal length of the ninth lens. Satisfying 2.0 < R1 / f1+R17 / f9 < 3.0 can reasonably distribute the optical power of the system, can make the system have good imaging quality and effectively reduce the sensitivity of the system.

[0055] In exemplary embodiments, at least one of the mirror surfaces of each of the first lens to the ninth lens is a non-spherical mirror surface. The present application does not specifically limit the specific number of spherical lenses and non-spherical lenses, and if the imaging quality is focused on, the lenses can all use non-spherical mirror surfaces. The characteristic of a non-spherical lens is that the curvature continuously changes from the center of the lens to the periphery of the lens. The characteristic of a spherical lens is that the curvature is constant from the center of the lens to the periphery. The non-spherical lens has better curvature radius characteristics and has the advantages of improving the distortion aberration and improving the astigmatism aberration. After using the non-spherical lens, the aberration that occurs during imaging can be eliminated as much as possible, thereby improving the imaging quality. Alternatively, the object side and the image side of each of the first lens to the ninth lens are non-spherical mirror surfaces.

[0056] In exemplary implementations, the effective focal length f1 of the first lens can be, for example, in a range from -9.0 mm to -8.0 mm, the effective focal length f2 of the second lens can be, for example, in a range from 6.0 mm to 7.0 mm, the effective focal length f3 of the third lens can be, for example, in a range from 15.0 mm to 18.0 mm, the effective focal length f4 of the fourth lens can be, for example, in a range from -120.0 mm to 5000.0 mm, the effective focal length f5 of the fifth lens can be, for example, in a range from 14.0 mm to 18.0 mm, the effective focal length f6 of the sixth lens can be, for example, in a range from 8.0 mm to 10.5 mm, the effective focal length f7 of the seventh lens can be, for example, in a range from -8.0 mm to -5.0 mm, the effective focal length f8 of the eighth lens can be, for example, in a range from 6.0 mm to 8.0 mm, the effective focal length f9 of the ninth lens can be, for example, in a range from -5.0 mm to -3.5 mm. The effective focal length f of the optical camera lens can be, for example, in a range from 6.0 mm to 7.0 mm. The maximum half field of view Semi-FOV of the optical camera lens can be, for example, in a range from 40.0° to 60.0°.

[0057] In exemplary implementations, the optical camera lens according to the present application further comprises a filter for correcting color deviation and / or a protection glass for protecting the photosensitive element located on the imaging plane.

[0058] The present application proposes an optical camera lens with large field of view, high pixel, miniaturization, and high imaging quality, etc. The optical camera lens according to the above embodiments of the present application can adopt multiple lenses, for example, nine lenses as mentioned above. By reasonably allocating the refractive power, surface type, central thickness of each lens, and on-axis distance between each lens, etc., the incident light can be effectively converged, the total optical length of the optical camera lens can be reduced, and the processability of the optical camera lens can be improved, so that the optical camera lens is more conducive to production and processing. However, those skilled in the art should understand that the number of lenses constituting the optical camera lens can be changed without departing from the technical solutions claimed by the present application, to obtain various results and advantages described in the specification. For example, although nine lenses are described in the embodiments, the optical camera lens is not limited to including nine lenses. If necessary, the optical camera lens can also include other numbers of lenses.
