For convenience, an aspheric surface of each lens surface uses the aspheric surfaces shown in the below condition (1). However, the present invention is not limited to the aspherical polynomials form shown in the condition (1).

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

Where, K is a conic coefficient, A4, A6, A8, A10, Al2, A14, A16, A18, A20 are aspheric surface coefficients. c is the curvature at the center of the optical surface. r is a vertical distance between a point on an aspherical curve and the optic axis, and z is an aspherical depth (a vertical distance between a point on an aspherical surface, having a distance of r from the optic axis, and a surface tangent to a vertex of the aspherical surface on the optic axis).

Table 3 and Table 4 show design data of inflexion points and arrest points of respective lens in the camera optical lens 10 according to Embodiment 1 of the present invention. P1R1 and P1R2 represent the object side surface and the image side surface of the first lens L1, P2R1 and P2R2 represent the object side surface and the image side surface of the second lens L2, P3R1 and P3R2 represent the object side surface and the image side surface of the third lens L3, P4R1 and P4R2 represent the object side surface and the image side surface of the fourth lens L4, and P5R1 and P5R2 represent the object side surface and the image side surface of the fifth lens L5. The data in the column named “inflexion point position” refers to vertical distances from inflexion points arranged on each lens surface to the optical axis of the camera optical lens 10. The data in the column named “arrest point position” refers to vertical distances from arrest points arranged on each lens surface to the optical axis of the camera optical lens 10.

FIG. 2 and FIG. 3 respectively illustrate a longitudinal aberration and a lateral color of light with wavelengths of 650 nm, 610 nm, 555 nm, 510 nm, 470 nm and 435 nm after passing the camera optical lens 10 according to Embodiment 1. FIG. 4 illustrates a field curvature and the distortion of light with a wavelength of 555 nm after passing the camera optical lens 10 according to Embodiment 1, in which a field curvature S is a field curvature in a sagittal direction and T is a field curvature in a tangential direction.

Table 17 in the following shows various values of Embodiments 1, 2, 3 and Comparative Embodiment, and also values corresponding to parameters which are specified in the above conditions.

As shown in Table 17, Embodiment 1 satisfies the above conditions.

In the present embodiment, the entrance pupil diameter (ENPD) of the camera optical lens 10 is 1.764 mm. The image height of 1.0H is 3.384 mm. The FOV is 84.00°. Thus, the camera optical lens 10 satisfies design requirements of large aperture, ultra-thin and wide-angle while the on-axis and off-axis aberrations are sufficiently corrected, thereby achieving excellent optical characteristics.

Embodiment 2

FIG. 10 and FIG. 11 respectively illustrate a longitudinal aberration and a lateral color of light with wavelengths of 650 nm, 610 nm, 555 nm, 510 nm, 470 nm and 435 nm after passing the camera optical lens 30 according to Embodiment 3. FIG. 12 illustrates a field curvature and a distortion of light with a wavelength of 555 nm after passing the camera optical lens 30 according to Embodiment 3, in which a field curvature S is a field curvature in a sagittal direction and T is a field curvature in a tangential direction.

Table 17 in the following lists values corresponding to the respective conditions. In the present Embodiment 3 in order to satisfy the above conditions.

In the present embodiment, an entrance pupil diameter (ENPD) of the camera optical lens is 1.663 mm. An image height of 1.0H is 3.384 mm. An FOV is 87.40°. Thus, the camera optical lens 30 satisfies design requirements of large aperture, ultra-thin and wide-angle while the on-axis and off-axis aberrations are sufficiently corrected, thereby achieving excellent optical characteristics.

Comparative Embodiment

Comparative Embodiment is basically the same as Embodiment 1 and involves symbols having the same meanings as Embodiment 1, and only differences therebetween will be described in the following. A third lens L3 has a positive refractive power. An object side surface of the third lens L3 is convex in a paraxial region and an image side surface of the third lens L3 is concave in the paraxial region. An object side surface of a fourth lens L4 is convex in the paraxial region.

FIG. 13 shows a schematic diagram of a structure of a camera optical lens 40 according to Comparative Embodiment in the present invention. Tables 13 and 14 show the design data of a camera optical lens 40 in Comparative Embodiment in the present invention.
