By properly controlling the distribution of positive and negative optical power across the system's components, the system's low-order aberrations can be effectively balanced, tolerance sensitivity can be reduced, and system miniaturization can be maintained.

[0045] In an exemplary embodiment, the optical camera lens of the present application may satisfy the conditional equation 13.0 < f5 / R9 + f5 / R10 < 37.0, where f5 is the effective focal length of the fifth lens element, R9 is the radius of curvature of the object-side surface of the fifth lens element, and R10 is the radius of curvature of the image-side surface of the fifth lens element. By controlling the effective focal length of the fifth lens element, the radius of curvature of the object-side surface of the fifth lens element, and the radius of curvature of the image-side surface of the fifth lens element to satisfy the conditional equation 13.0 < f5 / R9 + f5 / R10 < 37.0, the contribution of higher-order spherical aberration to the system can be controlled to a certain extent, resulting in a system with good imaging quality.

[0046] In an exemplary embodiment, the optical camera lens of the present application may satisfy the conditional equation 4.0 < |f9| / f1 < 31.0, where f9 is the effective focal length of the ninth lens element and f1 is the effective focal length of the first lens element.

[0047] In an exemplary embodiment, the optical camera lens of the present application may satisfy the conditional equation -9.0 < R2 / R1 < -4.0, where R2 is the radius of curvature of the image-side surface of the first lens, and R1 is the radius of curvature of the object-side surface of the first lens. By controlling the ratio of the radius of curvature of the image-side surface of the first lens to the radius of curvature of the object-side surface of the first lens within this range, the optical power of the system's first lens can be effectively controlled, achieving better light deflection at the first lens, and achieving better imaging effects.

By controlling the effective focal length of the second lens element, the radius of curvature of the object-side surface of the second lens element, and the radius of curvature of the image-side surface of the second lens element to satisfy the conditional equation: -7.0 < f2 / R3 + f2 / R4 < -5.0, the focal length and distortion of the system can be rationally controlled, ultimately keeping the focal length and distortion of the system within a certain range.

By controlling the ratio of the radius of curvature of the object-side surface of the fourth lens element to the radius of curvature of the image-side surface of the fourth lens element within this range, the deflection angle of light rays on the lens element can be reduced, enabling the system to better achieve deflection of the optical path.

[0051] In an exemplary embodiment, the optical camera lens of the present application may satisfy the conditional equation 0.5 < |(R11 + R12) / f6 | < 3.5, where R11 is the radius of curvature of the object-side surface of the sixth lens element, R12 is the radius of curvature of the image-side surface of the sixth lens element, and f6 is the effective focal length of the sixth lens element. By controlling the radius of curvature of the object-side surface of the sixth lens element, the radius of curvature of the image-side surface of the sixth lens element, and the effective focal length of the sixth lens element to satisfy the conditional equation 0.5 < |(R11 + R12) / f6 | < 3.5, the deflection of incident light at the sixth lens element can be effectively controlled, thereby reducing the system's sensitivity to decentering and tilt.

[0052] In an exemplary embodiment, the optical camera lens of the present application may satisfy the conditional equation 1.5 < T56 / T45 < 2.5, where T56 is the air spacing on the optical axis between the fifth and sixth lenses, and T45 is the air spacing on the optical axis between the fourth and fifth lenses. By controlling the ratio of the air spacing on the optical axis between the fifth and sixth lenses to the air spacing on the optical axis between the fourth and fifth lenses within a certain range, the system's field curvature can be effectively maintained, thereby achieving good imaging quality in the system's off-axis field of view.

[0053] In an exemplary embodiment, the optical camera lens of the present application can satisfy the conditional equation: 23.0 < CT1 / T12 < 43.0, where CT1 is the center thickness of the first lens on the optical axis, and T12 is the air gap between the first and second lenses on the optical axis. By controlling the ratio of the center thickness of the first lens on the optical axis to the air gap between the first and second lenses on the optical axis within a certain range, the amount of system distortion can be properly controlled, ultimately keeping the system distortion within a certain range.

[0054] In an exemplary embodiment, the optical camera lens of the present application may satisfy the condition 4.0 < CT3 / T34 < 12.0, where CT3 is the center thickness of the third lens on the optical axis, and T34 is the air spacing between the third and fourth lenses on the optical axis. By controlling the ratio of the center thickness of the third lens on the optical axis to the air spacing between the third and fourth lenses on the optical axis within a certain range, the manifestation of system coma can be properly controlled, resulting in excellent optical performance of the optical system.

[0055] In an exemplary embodiment, the optical camera lens of the present application can satisfy the conditional equation: -14.5 < f7 / R14 + f8 / R15 < 2.0, where f7 is the effective focal length of the seventh lens element, R14 is the radius of curvature of the image-side surface of the seventh lens element, f8 is the effective focal length of the eighth lens element, and R15 is the radius of curvature of the object-side surface of the eighth lens element. By controlling the effective focal length of the seventh lens element, the radius of curvature of the image-side surface of the seventh lens element, the effective focal length of the eighth lens element, and the radius of curvature of the object-side surface of the eighth lens element to satisfy the conditional equation: -14.5 < f7 / R14 + f8 / R15 < 2.0, the chief ray angle at the edge of the field of view can be controlled within a reasonable range, effectively reducing the sensitivity of the system.

[0056] In an exemplary embodiment, the optical camera lens of the present application may satisfy the conditional equation 2.0 < (CT7 + CT8 + CT9) / (T78 + T89) < 3.5, where CT7 is the center thickness of the seventh lens on the optical axis, CT8 is the center thickness of the eighth lens on the optical axis, CT9 is the center thickness of the ninth lens on the optical axis, T78 is the air spacing between the seventh and eighth lenses on the optical axis, and T89 is the air spacing between the eighth and ninth lenses on the optical axis. By controlling the ratio of the sum of the center thicknesses of the seventh lens, the eighth lens, and the ninth lens on the optical axis to the sum of the air spacing between the seventh and eighth lenses and the air spacing between the eighth and ninth lenses on the optical axis within a certain range, the field curvature generated by the front lens and the field curvature generated by the rear lens of the optical imaging system can be balanced, resulting in the optical imaging system having a reasonable field curvature.

[0057] In an exemplary embodiment, the optical camera lens of the present application may satisfy the conditional equation: -7.0 < f89 / R17 < 3.5, where f89 is the combined focal length of the eighth and ninth lenses, and R17 is the radius of curvature of the object-side surface of the ninth lens. By controlling the ratio of the combined focal length of the eighth and ninth lenses to the radius of curvature of the object-side surface of the ninth lens within this range, the contribution of higher-order spherical aberration to the system can be moderated, resulting in excellent imaging quality.

[0058] In an exemplary embodiment, the optical camera lens of the present application may satisfy the conditional expression 0.5 < |TAN(Semi-FOV) × f9| / (Fno × f) < 5.0, where Semi-FOV is half the maximum angular field of view of the optical camera lens, f9 is the effective focal length of the ninth lens element, Fno is the relative F-number of the optical camera lens, and f is the effective focal length of the optical camera lens. By controlling half the maximum angular field of view of the optical camera lens, the effective focal length of the ninth lens element, the relative F-number of the optical camera lens, and the effective focal length of the optical camera lens to satisfy the conditional expression 0.5 < |TAN(Semi-FOV) × f9| / (Fno × f) < 5.0, the optical system can achieve a large aperture while controlling the full angular field of view, thereby effectively controlling the imaging range of the system.

[0059] In an exemplary embodiment, the optical camera lens of the present application may satisfy the conditional formula -5.0<(SAG91+SAG92) / (SAG91-SAG92)<-2.0, wherein SAG91 is the on-axis distance from the intersection of the object side surface of the ninth lens and the optical axis to the effective radius vertex of the object side surface of the ninth lens, and SAG92 is the on-axis distance from the intersection of the image side surface of the ninth lens and the optical axis to the effective radius vertex of the image side surface of the ninth lens. By controlling the on-axis distance from the intersection of the object side surface of the ninth lens and the optical axis to the effective radius vertex of the object side surface of the ninth lens and the on-axis distance from the intersection of the image side surface of the ninth lens and the optical axis to the effective radius vertex of the image side surface of the ninth lens to satisfy the conditional formula -5.0<(SAG91+SAG92) / (SAG91-SAG92)<-2.0, the mid-thickness of the ninth lens can be effectively controlled, thereby improving the plasticity of the lens.

[0060] In an exemplary embodiment, the optical camera lens of the present application may include at least one aperture. The aperture can constrain the optical path and control the light intensity. The aperture can be positioned at an appropriate location in the optical camera lens, for example, between the object side and the first lens.

[0061] In an exemplary embodiment, optionally, the optical camera lens may further include a filter for correcting color deviation and / or a protective glass for protecting a photosensitive element located on the imaging surface.

[0062] The optical camera lens according to the above-mentioned embodiment of the present application can use multiple lenses, such as the nine lenses described above. By rationally controlling the positive and negative distribution of the optical power of each lens in the system, for example, setting the first, third, and fifth lenses to have positive optical power, the second, fourth, sixth, and seventh lenses to have negative optical power, and setting the eighth and ninth lenses to have positive or negative optical power, the low-order aberrations of the control system can be effectively balanced, and the sensitivity of the tolerance can be reduced, maintaining the miniaturization of the system. At the same time, by controlling the effective focal length f5 of the fifth lens and the curvature radius R9 of the object side surface of the fifth lens and the curvature radius R10 of the image side surface of the fifth lens to meet the conditional formula 13.0<f5 / R9+f5 / R10<37.0, the contribution of high-order spherical aberration to the system can be controlled to a certain extent, so that the system has good imaging quality.

[0063] Furthermore, according to the optical camera lens of the above-described embodiment of the present application, by properly controlling parameters such as the effective focal length, radius of curvature, center thickness, air spacing between adjacent lenses, and combined focal length of each lens, as well as parameters such as the total effective focal length, maximum field of view, and relative F-number of the optical camera lens, it is possible to balance the system's off-axis aberrations and properly control the system's focal length and distortion. This facilitates optimal light deflection of the system's light rays at each lens, resulting in better imaging effects; it also facilitates controlling the system's decentering sensitivity, resulting in better industrial process performance. Furthermore, it effectively ensures the system's field curvature, ensuring good imaging quality in the system's off-axis field of view; it properly controls the manifestation of system coma, ensuring excellent optical performance; and it can control the chief ray angle of the peripheral field of view within a reasonable range, effectively reducing the system's sensitivity. Furthermore, it enables the optical system to meet large aperture requirements while controlling the full field of view angle to effectively control the system's imaging range; and it also facilitates improving the plasticity of the lens.

[0064] In an embodiment of the present application, at least one aspherical mirror surface may be included in the mirror surfaces 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, that is, at least one aspherical mirror surface may be included from the object side surface of the first lens to the image side surface of the ninth lens. The characteristic of an aspherical lens is that the curvature changes continuously from the center of the lens to the periphery of the lens. Unlike a spherical lens with a constant curvature from the center of the lens to the periphery of the lens, an aspherical lens has a better curvature radius characteristic and has the advantages of improving distortion aberration and improving astigmatism aberration. After adopting an aspherical lens, the aberrations that occur during imaging can be eliminated as much as possible, thereby improving the imaging quality. Optionally, at least one of the object side surface and the image side surface of each lens in 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 mirror surface. Optionally, the object-side surface and the image-side 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 mirror surfaces.

[0065] However, those skilled in the art will appreciate that the number of lenses comprising the optical camera lens may be varied to achieve the various results and advantages described herein without departing from the claimed technical solutions. For example, while nine lenses are described in the embodiments, the optical camera lens is not limited to nine lenses. If desired, the optical camera lens may also include other numbers of lenses.
