For convenience, the aspheric surfaces of each lens use the aspheric surfaces shown in condition (1) below. However, the present disclosure is not limited to the polynomial form of aspheric surfaces represented by a condition (1).

z=(cr²)/{1+[1−k+1)(c²r²)]^1/2}+A4r⁴+A6r⁶+A8r⁸+A10r¹⁰+A12r¹²+A14r¹⁴+A16r¹⁶+A18r¹⁸+A20r²⁰ (1)

Here, k denotes a conic coefficient, and A4, A6, A8, A10, A12, A14, A16, A18, and A20 each denote an aspheric coefficient, respectively, c denotes an curvature at a center of an optical surface, r denotes a vertical distance between a point on a curve of the aspheric surface and the optical axis, and Z denotes an aspheric depth (i.e., a vertical distance between a point of the aspheric surface from which a distance to the optical axis is r, and a tangent plane tangent to a vertex on an aspheric optical axis).

Design data of the inflection point and the arrest point of each lens in the camera optical lens 10 according to Embodiment 1 of the present disclosure are shown in Tables 3 and 4. Here, P1R1 and P1R2 denote the object side surface and image side surface of the first lens L1, respectively. P2R1 and P2R2 denote the object side surface and image side surface of the second lens L2, respectively. P3R1 and P3R2 denote the object side surface and image side surface of the third lens L3, respectively. P4R1 and P4R2 denote the object side surface and image side surface of the fourth lens L4, respectively. P5R1 and P5R2 denote the object side surface and image side surface of the fifth lens L5, respectively. Data in an “inflection point” column are a vertical distance from an inflexion point provided on a surface of each lens to the optical axis of the camera optical lens 10. Data in an “arrest point” column are a vertical distance from an arrest point provided on the surface of each lens to the optical axis of the camera optical lens 10.

FIG. 14 and FIG. 15 are schematic diagrams of a longitudinal aberration and a lateral color of the camera optical lens 40 after light having a wavelength of 905 nm, 940 nm and 975 nm passes through the camera optical lens 40 according to Embodiment 4, respectively. FIG. 16 is a schematic diagram of a field curvature and a distortion of the camera optical lens 40 after light having a wavelength of 905 nm passes through the camera optical lens 40 according to Embodiment 4. A field curvature S in FIG. 16 is a field curvature in a sagittal direction, and T is a field curvature in a meridian direction.

Table 21 below lists the corresponding values of each condition in this embodiment according to the above conditions. It can be appreciated that the camera optical lens 40 of this embodiment satisfies the above conditions.

In this embodiment, the camera optical lens 40 has an entrance pupil diameter ENPD of 1.582 mm, a full-field image height IH of 2.265 mm, and a field of view FOV 67.06° in a diagonal direction. The camera optical lens 40 satisfies design requirements of large aperture, wide angle and ultra-thinness, and has on-axis and off-axis chromatic aberrations fully corrected, thereby having excellent optical performance.

Comparative Embodiment

Comparative Embodiment involves symbols having the same meanings as Embodiment 1, and only differences therebetween are listed below.

In this Comparative Embodiment, the object-side surface of the first lens L1 is concave in the paraxial region, the image-side surface of the first lens L1 is convex in the paraxial region, and the object-side surface of the fourth lens L4 is convex in the paraxial region. The first lens L1 is made of a plastic material.

FIG. 17 shows a camera optical lens 50 according to Comparative Embodiment.

Table 17 and Table 18 show the design data of the camera optical lens 50 of the Comparative Embodiment.
