[0110] Yc92, the vertical distance between the critical point of the image-side surface of the ninth lens and the optical axis. Detailed Implementation

[0111] The camera lens assembly comprises nine lenses, which are arranged sequentially from the object side to the image side along the light path as the first lens, second lens, third lens, fourth lens, fifth lens, sixth lens, seventh lens, eighth lens, and ninth lens.

[0112] In the camera optical lens assembly, each of the first to ninth lenses can have an air gap between any two adjacent lenses on the optical axis. That is, the first, second, third, fourth, fifth, sixth, seventh, eighth, and ninth lenses can be nine single, non-bonded lenses. Since the manufacturing process of bonded lenses is more complex than that of non-bonded lenses, especially since the bonding surfaces of the two lenses need to have highly precise curvature to achieve a high degree of fit during bonding, and misalignment during bonding can also lead to poor fit, affecting the overall optical imaging quality. Therefore, in the camera optical lens assembly of this invention, any two adjacent lenses can have an air gap on the optical axis, effectively avoiding the problems caused by bonded lenses and allowing for greater flexibility in the design of each lens surface, which helps to reduce volume and correct aberrations.

[0113] The first lens may have positive refractive power; thereby, it can provide the main converging ability to effectively compress the overall length of the camera optical lens assembly, achieving the requirement of miniaturization. The object-side surface of the first lens may be concave near the optical axis; thereby, the incident light path of the camera optical lens assembly can be adjusted to enhance image quality. The image-side surface of the first lens may be concave near the optical axis; thereby, it helps to adjust the refractive power of the first lens and correct off-axis aberrations. At least one of the object-side surface and the image-side surface of the first lens may have at least one critical point off-axis; thereby, it helps to further control the degree of change of the surface of the first lens to improve peripheral image quality. The object-side surface of the first lens may have at least one convex critical point off-axis; thereby, it helps to reduce the effective radius of the first lens in a wide-angle configuration, thereby further reducing the volume of the camera optical lens assembly, and thus allowing it to be configured in more electronic devices or devices with more stringent space constraints. Please refer to... Figure 28 This is a schematic diagram of the convex critical point C of the object-side surface 111 of the first lens in the first embodiment of the present invention.

[0114] The second lens can have positive refractive power. This allows it to complement or correct the optical path behind the first lens.

[0115] The eighth lens has positive refractive power; thereby, it can provide the main positive refractive power and effectively reduce the beam size in front of the imaging plane. The image-side surface of the eighth lens is convex near the optical axis; thereby, the back focal length can be adjusted, and the overall length of the imaging optical lens group can be further shortened. At least one of the object-side and image-side surfaces of the eighth lens may have at least one critical point off-axis; thereby, it helps to improve the illumination around the imaging plane and correct peripheral image aberrations. Please refer to... Figure 28 This is a schematic diagram of the critical point C between the object-side surface 181 and the image-side surface 182 of the eighth lens in the first embodiment of the present invention.

[0116] The ninth lens may have a negative refractive power; thereby, the principal point and the back focal length can be adjusted, and light rays can be incident on the imaging surface at a better angle. The image-side surface of the ninth lens is concave near the optical axis; thereby, it helps to further adjust the back focal length to meet the requirements of miniaturization. The image-side surface of the ninth lens has at least one convex critical point off the axis; thereby, the combination of the central and peripheral optical paths can be controlled, and the imaging optical lens group can have an appropriate back focal length. Please refer to Figure 28 , which is a schematic diagram of the critical point C of the object-side surface 191 and the image-side surface 192 of the ninth lens in the first embodiment of the present invention. Figure 28 Illustrate the critical points of the object-side surface of the first lens, the object-side surface of the eighth lens, the image-side surface of the eighth lens, the object-side surface of the ninth lens, and the image-side surface of the ninth lens in the first embodiment as an exemplary illustration. However, in each embodiment of the present invention, in addition to the first lens, the eighth lens, and the ninth lens, other lenses may also have one or more critical points.

[0117] The radius of curvature of the object-side surface of the eighth lens is R15, and the radius of curvature of the image-side surface of the eighth lens is R16, which satisfy the following conditions: -0.75 < (R15 + R16) / (R15 - R16). Thereby, it helps to provide a shape configuration with sufficient structural strength for the eighth lens and also helps to enhance the imaging quality. Among them, the following conditions may also be satisfied: -0.50 < (R15 + R16) / (R15 - R16). Among them, the following conditions may also be satisfied: -0.30 < (R15 + R16) / (R15 - R16) < 4.0. Among them, the following conditions may also be satisfied: 0.0 < (R15 + R16) / (R15 - R16) < 3.50. Among them, the following conditions may also be satisfied: 0.30 < (R15 + R16) / (R15 - R16) < 3.0.

[0118] The F-number of the imaging optical lens group is Fno, which satisfies the following conditions: Fno < 2.60. Thereby, the aperture configuration can be further strengthened, and the imaging optical lens group can provide sufficient light intake. Among them, the following conditions may also be satisfied: 1.0 < Fno < 2.30. Among them, the following conditions may also be satisfied: 1.20 < Fno < 2.10.

[0119] The focal length of the imaging optical lens group is f, the radius of curvature of the object-side surface of the eighth lens is R15, and the radius of curvature of the image-side surface of the eighth lens is R16, which can satisfy the following conditions: 1.0 < |f / R15| + |f / R16|. Thereby, the shape configuration of the eighth lens helps to correct aberration to improve the imaging quality. Among them, the following conditions may also be satisfied: 1.33 < |f / R15| + |f / R16| < 8.0.

[0120] The distance from the object side surface of the first lens to the imaging surface on the optical axis is TL, and the maximum imaging height of the imaging optical lens group is ImgH (i.e., half of the total diagonal length of the effective sensing area of the electronic photosensitive component). It can meet the following conditions: TL / ImgH < 3.0. Thereby, it helps to ensure that the imaging optical lens group can achieve an appropriate balance between miniaturization and module manufacturability. Among them, the following conditions can also be met: TL / ImgH < 2.0. Among them, the following conditions can also be met: 1.0 < TL / ImgH < 1.50.

[0121] The focal length of the imaging optical lens group is f, and the radius of curvature of the image side surface of the eighth lens is R16, and the radius of curvature of the object side surface of the ninth lens is R17. It can meet the following conditions: 1.20 < |f / R16| + |f / R17|. Thereby, the back focal length can be further shortened to make better use of the limited space. Among them, the following conditions can also be met: 1.60 < |f / R16| + |f / R17| < 8.0.

[0122] The perpendicular distance between the critical point of the object side surface of the eighth lens and the optical axis is Yc81, and the perpendicular distance between the critical point of the image side surface of the ninth lens and the optical axis is Yc92. It can meet the following conditions: 0.50 < Yc92 / Yc81 < 2.30. Thereby, it helps to correct the off-axis aberration at the image side end and control the back focal length of the system at the same time. Among them, the following conditions can also be met: 0.50 < Yc92 / Yc81 < 1.75. Please refer to Figure 28 , which is a schematic diagram of the parameters Yc81 and Yc92 in the first embodiment of the present invention.

[0123] The number of lenses in the imaging optical lens group with an Abbe number less than 40 is V40. It can meet the following conditions: 4 ≤ V40. Thereby, it helps to strengthen the correction of chromatic aberration. Among them, the number of lenses in the imaging optical lens group with an Abbe number less than 26 is V26. It can meet the following conditions: 3 ≤ V26. Among them, the number of lenses in the imaging optical lens group with an Abbe number less than 20 is V20. It can meet the following conditions: 2 ≤ V20.

[0124] The distance from the object side surface of the first lens to the imaging surface on the optical axis is TL, and the focal length of the imaging optical lens group is f. It can meet the following conditions: TL / f < 4.0. Thereby, the total length of the imaging optical lens group can be effectively controlled to be configured in devices with more diverse uses. Among them, the following conditions can also be met: TL / f < 1.40. Among them, the following conditions can also be met: 1.40 < TL / f < 3.50.

[0125] In the imaging optical lens group, the maximum viewing angle is FOV, which satisfies the following conditions: 90° < FOV < 150°. Thereby, the imaging optical lens group can capture the most commonly used image range to meet the needs of most products.

[0136] Each technical feature in the above-mentioned imaging optical lens group of the present invention can be combined and configured to achieve the corresponding effects.

[0137] In the imaging optical lens group disclosed by the present invention, the material of the lens can be glass or plastic. If the material of the lens is glass, the degree of freedom of the refractive power configuration of the imaging optical lens group can be increased, and the influence of the external environmental temperature change on imaging can be reduced. The glass lens can be made by techniques such as grinding or molding. If the lens material is plastic, the production cost can be effectively reduced. Among them, in the imaging optical lens group disclosed by the present invention, at least half of the lenses can be made of plastic material; thereby, the degree of freedom of the lens shape design can be increased, which is beneficial to lens manufacturing and aberration correction. In addition, a spherical surface or an aspherical surface (ASP) can be provided on the lens surface. The spherical lens can reduce the manufacturing difficulty. If an aspherical surface is provided on the lens surface, more control variables can be obtained thereby to eliminate aberrations, reduce the number of lenses, and effectively reduce the total length of the imaging optical lens group of the present invention. Further, the aspherical surface can be made by methods such as plastic injection molding or molding glass lenses.

[0138] In the imaging optical lens group disclosed by the present invention, if the lens surface is an aspherical surface, it means that all or a part of the optical effective area of the lens surface is an aspherical surface.

[0139] In the imaging optical lens group disclosed by the present invention, additives can be selectively added to any (or more) lens materials to change the light transmittance of the lens for light in a specific wavelength band, thereby reducing stray light and color deviation. For example: the additive can have the function of filtering light in the wavelength band of 600 nm to 800 nm in the system to help reduce excess red light or infrared light; or it can filter light in the wavelength band of 350 nm to 450 nm to reduce excess blue light or ultraviolet light. Therefore, the additive can avoid interference of light in a specific wavelength band on imaging. In addition, the additive can be uniformly mixed in the plastic and made into a lens by injection molding technology.

[0140] In the camera optical lens assembly disclosed in this invention, if the lens surface is convex and the position of the convex surface is not defined, it means that the convex surface can be located near the optical axis of the lens surface; if the lens surface is concave and the position of the concave surface is not defined, it means that the concave surface can be located near the optical axis of the lens surface. If the refractive power or focal length of the lens is not defined in its region, it means that the refractive power or focal length of the lens can be the refractive power or focal length of the lens near the optical axis.

[0141] In the camera optical lens assembly disclosed in this invention, the critical point on the lens surface refers to the point of tangency on the tangent line between the plane perpendicular to the optical axis and the lens surface, and the critical point is not located on the optical axis.

[0142] In the camera optical lens assembly disclosed in this invention, the imaging surface of the camera optical lens assembly can be a plane or a curved surface with any curvature, depending on the corresponding electronic photosensitive component, especially a curved surface with a concave surface facing the object side.

[0143] In the imaging optical lens assembly disclosed in this invention, one or more imaging correction components (such as planar components) can be selectively disposed between the lens closest to the imaging plane and the imaging plane in the imaging optical path to achieve the effect of correcting image curvature (e.g., image bending). The optical properties of this imaging correction component, such as curvature, thickness, refractive index, position, and surface type (convex or concave, spherical or aspherical, diffractive surface, and Fresnel surface, etc.), can be adjusted according to the requirements of the imaging device. Generally, a preferred configuration of the imaging correction component is to place a thin plano-concave component with a concave surface in the object-side direction near the imaging plane.

[0144] In the camera optical lens assembly disclosed in this invention, at least one component with a deflecting optical path function, such as a prism or a mirror, can be selectively disposed between the object and the imaging plane in the imaging optical path. This provides a more flexible spatial configuration for the camera optical lens assembly, allowing the thinning and lightening of electronic devices to be unrestricted by the total optical length of the camera optical lens assembly. For further explanation, please refer to... Figure 31 and Figure 32 ,in Figure 31 This is a schematic diagram illustrating one configuration of the optical path deflection component of the present invention within a camera optical lens assembly, and Figure 32 This is a schematic diagram illustrating another configuration of the optical path deflection component of the present invention within a camera optical lens assembly. For example... Figure 31 and Figure 32 As shown, the camera optical lens assembly can travel along the light path from the subject (not shown) to the imaging plane IM, and sequentially includes a first optical axis OA1, an optical path deflection component LF, and a second optical axis OA2, wherein the optical path deflection component LF can be as follows: Figure 31The image shown is a lens group LG positioned between the subject and the camera lens assembly, or as... Figure 32 The diagram shows the lens group LG positioned between the imaging plane IM and the optical lens assembly for imaging. Please also refer to... Figure 33 This is a schematic diagram illustrating the configuration of the two optical path deflection components of the present invention within a camera optical lens assembly. For example... Figure 33 As shown, the camera optical lens assembly can also travel along the light path from the subject (not shown) to the imaging plane IM, and sequentially includes a first optical axis OA1, a first optical path reversing component LF1, a second optical axis OA2, a second optical path reversing component LF2, and a third optical axis OA3. The first optical path reversing component LF1 is disposed between the subject and the lens group LG of the camera optical lens assembly, and the second optical path reversing component LF2 is disposed between the lens group LG of the camera optical lens assembly and the imaging plane IM. Furthermore, the direction of light travel along the first optical axis OA1 can be as follows: Figure 33 The direction shown is the same as the direction of light travel along the third optical axis OA3. The camera lens assembly may also selectively be configured with more than three optical path deflection components; the present invention is not limited to the type, number, and position of the optical path deflection components disclosed in the figures.

[0145] The camera optical lens assembly disclosed in this invention may include at least one aperture stop, which may be located before the first lens, between the lenses, or after the last lens. The aperture stop may be of the type such as a glare stop or a field stop, and may be used to reduce stray light and help improve image quality.

[0146] In the camera optical lens assembly disclosed in this invention, the aperture can be configured as a front aperture or a center aperture. A front aperture means the aperture is positioned between the subject and the first lens, while a center aperture means the aperture is positioned between the first lens and the imaging plane. A front aperture allows for a longer distance between the exit pupil and the imaging plane, resulting in a telecentric effect and increasing the efficiency of image reception by the CCD or CMOS sensor. A center aperture helps to expand the field of view of the camera optical lens assembly.

[0147] This invention may appropriately incorporate a variable aperture component, which can be a mechanical component or a light control component, capable of electrically or by electrical signals controlling the size and shape of the aperture. The mechanical component may include movable parts such as a blade assembly or a shielding plate; the light control component may include a filter component, an electrochromic material, a liquid crystal layer, or other masking materials. This variable aperture component can enhance image adjustment capabilities by controlling the amount of light entering the image or the exposure time. Furthermore, this variable aperture component can also be the aperture of this invention, allowing adjustment of image quality, such as depth of field or exposure speed, by changing the aperture value.

[0148] Based on the above implementation methods, specific embodiments are presented below and described in detail with reference to the accompanying drawings.
