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

$\begin{matrix} z = (c r^{2}) / {1 + {[1 - (k + 1) (c^{2} r^{2})]}^{1 / 2}} + A 4 r^{4} + A 6 r^{6} + A 8 r^{8} + A 1 0 r^{1 0} + A 1 2 r^{1 2} + A 1 4 r^{1 4} + A 1 6 r^{1 6} + A 18 r^{1 8} + A 2 0 r^{2 0} & (1) \end{matrix}$

In equation (1) above, k is the conic coefficient, A4, A6, A8, A10, A12, A14, A16, A18, A20 are the aspheric coefficients, c is the curvature at the center of the optical surface, r is the vertical distance between the point on the curved line of the aspheric surface and an optical axis, and z is a depth of the aspheric surface (the vertical distance between the point on the aspheric surface, with a distance of r from the optical axis, and the tangent plane to the vertex on the aspheric surface)

Table 3 and Table 4 show design data of inflection points and arrest points of each lens of the camera optical lens 10 according to the first embodiment of the present disclosure. P1R1 and P1R2 represent the object-side surface and the image-side surface of the first lens L1, respectively. P2R1 and P2R2 represent the object-side surface and the image-side surface of the second lens L2, respectively. P3R1 and P3R2 represent the object-side surface and the image-side surface of the third lens L3, respectively. P4R1 and P4R2 represent the object-side surface and the image-side surface of the fourth lens L4, respectively. P5R1 and P5R2 represent the object-side surface and the image-side surface of the fifth lens L5, respectively. The data corresponding to the column “inflection point position” is the vertical distance from the inflection point provided on the surface of each lens to the optical axis of the camera optical lens 10. The data corresponding to the column “arrest point position” is a vertical distance from the arrest point provided on the surface of each lens to the optical axis of the camera optical lens 10.

FIG. 26 and FIG. 27 show schematic diagrams of a longitudinal aberration and a lateral color of light with wavelengths of 470 nm, 510 nm, 555 nm, 610 nm and 650 nm after passing through the camera optical lens 70 according to the comparative embodiment, respectively. FIG. 28 shows a field curvature and a distortion of light with a wavelength of 555 nm after passing through the camera optical lens 70 according to the comparative embodiment. The field curvature S in FIG. 28 is a field curvature in a sagittal direction, and the field curvature T is a field curvature in a meridian direction.

The following Table 29 lists the values corresponding to each conditional in the comparative embodiment according to the above conditionals. For the camera optical lens 70 of the comparative embodiment, (R3+R4)/(R3−R4)=3.00, which does not satisfy the relation 3.20≤(R3+R4)/(R3−R4)≤4.70.

In the comparative embodiment, the entrance pupil diameter ENPD of the camera optical lens 70 is 0.414 mm, the full-field image height IH is 1.480 mm, and the field of view FOV in the diagonal direction is 194.00°. The on-axis and off-axis color aberrations of the camera optical lens 70 have not been fully corrected.
