For convenience, the aspheric surface of each lens surface uses the aspheric surface shown in following formula (1). However, the present disclosure is not limited to the aspheric polynomial form shown in formula (1).

$\begin{matrix} z = ({cr}^{2}) / {1 + {[1 - (k + 1) (c^{2} r^{2})]}^{1 / 2}} + A 4 r^{4} + A 6 r^{6} + A 8 r^{8} + A 10 r^{10} + A 12 r^{12} + A 14 r^{14} + A 16 r^{16} ++ A 18 r^{18} + A 20 r^{20} + A 22 r^{22} + A 24 r^{24} + A 26 r^{26} + A 28 r^{28} + A 30 r^{30} & (1) \end{matrix}$

Where k denotes a conic coefficient, A4, A6, A8, A10, A12, A14, A16, A18, A20, A22, A24, A26, A28 and A30 denote aspheric coefficients, c denotes a curvature at a center of an optical surface, r denotes a vertical distance between a point on an aspheric curve and an optical axis, and z denotes an aspheric depth (a vertical distance between a point on the aspheric surface, with a distance r from the optical axis, and a tangent plane tangent to a vertex on the aspheric optical axis).

Table 3 and Table 4 show design data of inflection points and arrest points of each lens in the camera optical lens 10 according to Embodiment 1 of the present disclosure. P1R1 and P1R2 respectively denote the object side surface and the image side surface of the first lens L1, P2R1 and P2R2 respectively denote the object side surface and the image side surface of the second lens L2, P3R1 and P3R2 respectively denote the object side surface and the image side surface of the third lens L3, P4R1 and P4R2 respectively denote the object side surface and the image side surface of the fourth lens L4, P5R1 and P5R2 respectively denote the object side surface and the image side surface of the fifth lens L5, P6R1 and P6R2 respectively denote the object side surface and the image side surface of the fifth lens L6. The corresponding data in the column “Inflection Point Position” is a vertical distance from the inflection points on the surface of each lens to the optical axis of the camera optical lens 10. The corresponding data in the column “Arrest Point Position” is a vertical distance from the arrest points on the surface of each lens to the optical axis of the camera optical lens 10.

FIG. 6 and FIG. 7 respectively show longitudinal aberration and lateral color of light with wavelengths of 650 nm, 610 nm, 555 nm, 510 nm, 470 nm, and 435 nm after passing through the camera optical lens 20 according to Embodiment 2. FIG. 8 shows field curvature and distortion of light with a wavelength of 555 nm after passing through the camera optical lens 20 according to Embodiment 2. The field curvature S in FIG. 8 is the field curvature in a sagittal direction, and T is the field curvature in a meridian direction.

As shown in Table 25, Embodiment 2 satisfies relational expressions.

In the embodiment, the entrance pupil diameter ENPD of the camera optical lens 20 is 3.436 mm, the full field of view image height IH is 3.133 mm, and the field of view FOV in the diagonal direction is 50.37°, the camera optical lens 20 meets the design requirements of large-aperture and ultra-thinness, the on-axis and off-axis chromatic aberration are fully corrected, and has excellent optical characteristics.

Embodiment 3

Embodiment 3 is substantially the same as Embodiment 1, the reference signs have the same meaning as Embodiment 1, and only differences are listed below.

FIG. 9 shows a camera optical lens 30 according to Embodiment 3 of the present disclosure.

FIG. 22 and FIG. 23 respectively show longitudinal aberration and lateral color of light with wavelengths of 650 nm, 610 nm, 555 nm, 510 nm, 470 nm, and 435 nm after passing through the camera optical lens 60 according to Comparative Embodiment. FIG. 24 shows field curvature and distortion of light with a wavelength of 555 nm after passing through the camera optical lens 60 according to Comparative Embodiment. The field curvature S in FIG. 24 is the field curvature in a sagittal direction, and T is the field curvature in a meridian direction.

Table 25 below lists values corresponding to each relational expression in Comparative Embodiment according to the above relational expressions. The camera optical lens 60 of Comparative Embodiment does not satisfy the above relational expression 0.10≤d8/TTL≤0.20.

In Comparative Embodiment, the entrance pupil diameter ENPD of the camera optical lens 60 is 3.625 mm, the full field of view image height IH is 3.133 mm, and the field of view FOV in the diagonal direction is 41.50°, the camera optical lens 60 does not meet the design requirements of large-aperture and ultra-thinness.
