CAMERA OPTICAL LENS

TECHNICAL FIELD

The present disclosure relates to the field of optical lens, and more particularly, to a camera optical lens suitable for handheld terminal devices such as smart phones or digital cameras and camera devices such as monitors or PC lenses.

BACKGROUND

With the emergence of smart phones in recent years, the demand for miniature camera lens is increasing day by day, but in general the photosensitive devices of camera lens are nothing more than Charge Coupled Device (CCD) or Complementary Metal-Oxide Semiconductor Sensor (CMOS sensor), and as the progress of the semiconductor manufacturing technology makes the pixel size of the photosensitive devices become smaller, plus the current development trend of electronic products towards better functions and thinner and smaller dimensions, miniature camera lenses with good imaging quality therefore have become a mainstream in the market.

In order to obtain better imaging quality, the lens that is traditionally equipped in mobile phone cameras adopts a three-piece or four-piece lens structure, or even a five-piece or six-piece structure. Also, with the development of technology and the increase of the diverse demands of users, and as the pixel area of photosensitive devices is becoming smaller and smaller and the requirement of the system on the imaging quality is improving constantly, an eight-piece lens structure gradually appears in lens designs. Although the common eight-piece lens has good optical performance, its settings on refractive power, lens spacing and lens shape still have some irrationality, which results in that the lens structure cannot achieve a high optical performance while satisfying design requirements for ultra-thin, wide-angle lenses having a big aperture.

In the present embodiment, an aspheric surface of each lens surface uses the aspheric surfaces shown in the above condition (1). However, the present disclosure is not limited to the aspherical polynomials form shown in the condition (1).

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 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, P6R1 and P6R2 represent the object side surface and the image side surface of the sixth lens L6, respectively, P7R1 and P7R2 represent the object side surface and the image side surface of the seventh lens L7, respectively, and P8R1 and P8R2 represent the object side surface and the image side surface of the eighth lens L8, respectively. The data in the column named “inflexion point position” refers to vertical distances from inflexion points arranged on each lens surface to the optic 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 optic axis of the camera optical lens 10.

FIG. 2 and FIG. 3 illustrate a longitudinal aberration and a lateral color of light with wavelengths of 656 nm, 587 nm, 546 nm, 486 nm and 436 nm after passing the camera optical lens 10 according to Embodiment 1. FIG. 4 illustrates a field curvature and a distortion of light with a wavelength of 546 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 21 below further lists various values of Embodiments 1, 2, and 3 and values corresponding to parameters which are specified in the above conditions.

As shown in Table 21, Embodiment 1 satisfies respective conditions.

In this embodiment, the entrance pupil diameter of the camera optical lens is 4.052 mm. The image height of 1.0H is 8.00 mm. The FOV (field of view) is 89.80°. Thus, the camera optical lens can achieve ultra-thin, wide-angle lenses while having on-axis and off-axis aberrations sufficiently corrected, thereby leading to better optical characteristics.

Embodiment 2

Embodiment 2 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.

FIG. 10 and FIG. 11 illustrate a longitudinal aberration and a lateral color of light with wavelengths of 656 nm, 587 nm, 546 nm, 486 nm and 436 nm after passing the camera optical lens 30 according to Embodiment 3. FIG. 12 illustrates field curvature and distortion of light with a wavelength of 546 nm after passing the camera optical lens 30 according to Embodiment 3.

Table 21 below further lists various values of the present embodiment and values corresponding to parameters which are specified in the above conditions. Obviously, the camera optical lens according to this embodiment satisfies the above conditions.

In this embodiment, the entrance pupil diameter of the camera optical lens is 4.071 mm. The image height of 1.0H is 8.00 mm. The FOV (field of view) is 90.00°. Thus, the camera optical lens can achieve ultra-thin, wide-angle lenses while having on-axis and off-axis aberrations sufficiently corrected, thereby leading to better optical characteristics.

Embodiment 4

Embodiment 4 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.

FIG. 18 and FIG. 19 illustrate a longitudinal aberration and a lateral color of light with wavelengths of 656 nm, 587 nm, 546 nm, 486 nm and 436 nm after passing the camera optical lens 50 according to Embodiment 5. FIG. 20 illustrates field curvature and distortion of light with a wavelength of 546 nm after passing the camera optical lens 50 according to Embodiment 5.

In this embodiment, the entrance pupil diameter of the camera optical lens is 4.02 mm. The image height of 1.0H is 8.00 mm. The FOV (field of view) is 90.00°. Thus, the camera optical lens can achieve ultra-thin, wide-angle lenses while having on-axis and off-axis aberrations sufficiently corrected, thereby leading to better optical characteristics.
