[0099] The optical imaging lens group includes nine lenses, and the nine lenses are sequentially arranged from the object side to the image side along the optical path, namely, 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 nine lenses respectively have an object side surface facing the object side direction and an image side surface facing the image side direction.

[0100] The first lens has negative refractive power, thereby helping to expand the viewing angle to obtain a wider range of image information.

[0101] The second lens has negative refractive power, which can effectively share the refractive power of the first lens to avoid excessive curvature of the first lens and excessive aberration. The object side surface of the second lens can be convex near the optical axis, which can adjust the surface shape and refractive power of the second lens, which helps to improve the quality of the central image. The image side surface of the second lens is concave near the optical axis, which can adjust the surface shape of the image side of the second lens, which helps to reduce the aberration caused by the incident light of a large viewing angle.

[0102] The image-side surface of the third lens element may be convex near the optical axis, thereby balancing spherical aberration and coma.

[0103] The object side surface of the fourth lens can be concave near the optical axis, which helps to balance the incident angle of the large-angle light entering the fourth lens and avoid light divergence. The image side surface of the fourth lens is convex near the optical axis, which can provide the fourth lens with the ability to converge light and avoid insufficient deflection of light in the peripheral area, resulting in ineffective focusing.

[0104] The fifth lens may have positive refractive power, thereby helping to converge light to compress the volume. The object side surface of the fifth lens may be convex near the optical axis, thereby adjusting the surface shape and refractive power of the fifth lens, helping to compress the volume and correct aberrations.

[0105] The sixth lens may have negative refractive power, thereby balancing the refractive power of the seventh lens and reducing the back focal length. The image side surface of the sixth lens is concave near the optical axis, thereby adjusting the direction of light emission from the sixth lens, which helps to increase the imaging surface.

[0106] The object side surface of the seventh lens element may be convex near the optical axis, thereby helping to compress the back focus length and correct off-axis aberrations.

[0107] The eighth lens has negative refractive power, which can effectively control the back focal length of the optical imaging lens group to avoid the total length of the optical imaging lens group being too long. The object side surface of the eighth lens is concave near the optical axis, which can control the incident angle of the light incident on the object side surface of the eighth lens to avoid excessive incident angles that cause light divergence and poor peripheral relative illumination.

[0108] At least one of the nine lenses of the optical imaging lens group may have at least one inflection point. In detail, among the first to ninth lenses, one or more lenses may have at least one inflection point, and the single lens having at least one inflection point means that at least one of the object side surface and the image side surface of the single lens has at least one inflection point. Thereby, the degree of freedom of optical design can be increased, which is beneficial to lens manufacturing and aberration correction. Among them, at least one of the object side surface of the third lens and the image side surface of the third lens may have at least one inflection point; thereby, the peripheral surface design of the third lens can be adjusted to facilitate astigmatism correction. Among them, the object side surface of the third lens may have at least one inflection point. Among them, the image side surface of the eighth lens may have at least one inflection point; thereby, the incident angle of light on the imaging surface can be adjusted, and the peripheral light angle can be controlled to avoid dark corners around the image and reduce distortion. At least one of the object side surface of the ninth lens and the image side surface of the ninth lens may have at least one inflection point; thereby, the ability of the ninth lens to correct peripheral image aberrations is enhanced. Fig.33 , a schematic diagram showing an inflection point P on a lens surface according to the first embodiment of the present disclosure. Fig.33 , the object-side surface and image-side surface of the third lens E3, the object-side surface of the seventh lens E7, the object-side surface of the eighth lens E8 and the image-side surface of the ninth lens E9 each have one inflection point P, and the image-side surface of the eighth lens E8 and the object-side surface of the ninth lens E9 each have two inflection points P. Fig.33 The first embodiment of the present disclosure is shown as an exemplary illustration. However, in other embodiments of the present disclosure, each lens may have one or more inflection points.

In this way, the radius of curvature of the object side surface of the third lens and the radius of curvature of the image side surface of the fourth lens can be effectively balanced. By adjusting the radius of curvature of the object side surface of the third lens to balance the large-angle light entering the optical imaging lens group, and adjusting the radius of curvature of the image side surface of the fourth lens to converge the light, it is helpful to compress the volume of the optical imaging lens group. Among them, the following conditions can also be met: 0.30<(R5+R8) / (R5-R8)<8.00. Among them, the following conditions can also be met: 0.50<(R5+R8) / (R5-R8)<5.00.

Among them, the following conditions can also be satisfied: 1.10 < (R3 + R4) / (R3 - R4) < 6.00. Among them, the following conditions can also be satisfied: 1.20 < (R3 + R4) / (R3 - R4) < 4.00.

Thereby, it can adjust the ratio of the distance between the second lens and the third lens, the distance between the third lens and the fourth lens, the distance between the fourth lens and the fifth lens, and the distance between the seventh lens and the eighth lens, and helps to balance the spatial configuration of the lenses to reduce the sensitivity of the optical imaging lens group. Among them, the following conditions can also be satisfied: 0 < (T34 + T45 + T78) / T23 < 1.00. Among them, the following conditions can also be satisfied: 0.01 < (T34 + T45 + T78) / T23 < 0.75.

Among them, the following conditions can also be satisfied: 0.70 < T23 / (CT1 + CT2) < 2.50. Among them, the following conditions can also be satisfied: 0.80 < T23 / (CT1 + CT2) < 2.20.

Thereby, the refractive powers of the third lens, the seventh lens, and the ninth lens can be adjusted, which helps to balance the convergence or divergence of the large-angle incident light rays and improve the light-gathering quality of the entire field of view. Among them, the following conditions can also be satisfied: 0.05 < (|f / f3| + |f / f9|) / |f / f7| < 0.60.

[0116] The thickness of the fourth lens on the optical axis is CT4, and the thickness of the fifth lens on the optical axis is CT5, which can satisfy the following conditions: 0.40 < CT4 / CT5 < 2.50. Thereby, the ratio of the center thickness of the fourth lens to the center thickness of the fifth lens can be balanced, which helps to reduce manufacturing tolerances. Among them, the following conditions can also be satisfied: 0.60 < CT4 / CT5 < 2.00.

[0117] The focal length of the optical imaging lens group is f, and the focal length of the third lens is f3, which can satisfy the following conditions: |f / f3| < 0.45.

Among them, the following conditions can also be satisfied: 0.01 < |f / f3| < 0.25.

[0118] 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 optical imaging lens group is ImgH (which can be half of the total diagonal length of the effective sensing area of the electronic photosensitive element), which can satisfy the following conditions: 3.00 < TL / ImgH < 8.00. Thereby, the total optical length can be effectively compressed under a sufficient imaging size. Among them, the following conditions can also be satisfied: 4.00 < TL / ImgH < 7.00. Please refer to Fig.34, showing a schematic diagram of the parameter ImgH in the first embodiment of the present disclosure.

[0119] The maximum viewing angle of the optical imaging lens group is FOV, which can satisfy the following conditions: 150.0 degrees < FOV < 230.0 degrees. Thereby, the optical imaging lens group can have a sufficient imaging range to meet the field of view requirements of the application device.
