Description:
FIELD OF THE PRESENT DISCLOSURE 
     The present disclosure relates to the field of optical lens, more particularly, to a camera optical lens suitable for handheld terminal devices, such as smart phones and digital cameras, and imaging devices such as monitors or PC lenses. 
     DESCRIPTION OF RELATED ART 
     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. 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, the five-piece, six-piece and seven-piece lens structures gradually appear in lens designs. There is an urgent need for ultra-thin, wide-angle camera lenses with good optical characteristics and fully corrected chromatic aberration.

       FIG. 2  and  FIG. 3  respectively illustrate 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 the camera optical lens  10  according to Embodiment 1.  FIG. 4  illustrates a field curvature and a 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 13 described below shows the various values of the Embodiments 1, 2, 3 and the values corresponding to the parameters which are specified in the conditions. 
     As shown in Table 13, Embodiment 1 satisfies the above conditions. 
     In this embodiment, an entrance pupil diameter of the camera optical lens is 1.944 mm. An image height of 1.0H is 3.147 mm. A FOV is 80.00°. Thus, the camera optical lens has a wide-angle and is ultra-thin. Its on-axis and off-axis chromatic aberrations are fully corrected, thereby achieving excellent optical characteristics. 
     Embodiment 2 
     Embodiment 2 is basically the same as Embodiment 1, the meaning of its symbols is the same as that of Embodiment 1, in the following, only the differences are listed. 
     Table 5 and table 6 show the design data of a camera optical lens  20  in Embodiment 2 of the present invention.

       FIG. 6  and  FIG. 7  respectively illustrate 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 the camera optical lens  20  according to Embodiment 2.  FIG. 8  illustrates a field curvature and the distortion of light with a wavelength of 555 nm after passing the camera optical lens  20  according to Embodiment 2, in which a field curvature S is a field curvature in a sagittal direction and T is a field curvature in a tangential direction. 
     As shown in Table 13, Embodiment 2 satisfies the above conditions. 
     In this embodiment, the entrance pupil diameter of the camera optical lens is 1.944 mm. The image height of 1.0H is 3.147 mm. The FOV is 82.80°. Thus, the camera optical lens has a wide-angle and is ultra-thin. Its on-axis and off-axis chromatic aberrations are fully corrected, thereby achieving excellent optical characteristics.

       FIG. 10  and  FIG. 11  respectively illustrate 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 the camera optical lens  30  according to Embodiment 3.  FIG. 8  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. 
     The following table 13, in accordance with the above conditions, lists the values in this embodiment corresponding to each condition. Apparently, the camera optical lens of this embodiment satisfies the above conditions. 
     In this embodiment, the entrance pupil diameter of the camera optical lens is 1.901 mm. The image height of 1.0H is 3.147 mm. The FOV is 80.00°. Thus, the camera optical lens has a wide-angle and is ultra-thin. Its on-axis and off-axis chromatic aberrations are fully corrected, thereby achieving excellent optical characteristics.
