Description:
FIELD OF THE PRESENT INVENTION 
     The present invention relates to the field of optical lens, and 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.

     For convenience, an aspheric surface of each lens surface uses the aspheric surfaces shown in the above condition (1). However, the present invention 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 invention. P1R1 and P1R2 represent the object side surface and the image side surface of the first lens L 1 , P2R1 and P2R2 represent the object side surface and the image side surface of the second lens L 2 , P3R1 and P3R2 represent the object side surface and the image side surface of the third lens L 3 , P4R1 and P4R2 represent the object side surface and the image side surface of the fourth lens L 4 , P5R1 and P5R2 represent the object side surface and the image side surface of the fifth lens L 5 , and P6R1 and P6R2 represent the object side surface and the image side surface of the sixth lens L 6 . 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 470 nm, 555 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 shows various values of Embodiments 1, 2 and 3 and values corresponding to parameters which are specified in the above conditions. 
     As shown in Table 13, Embodiment 1 satisfies the above conditions. 
     In this embodiment, the entrance pupil diameter of the camera optical lens  10  is 1.870 mm. The image height of 1.0H is 3.284 mm. The FOV (field of view) is 80.87°. 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. 6  and  FIG. 7  respectively illustrate a longitudinal aberration and a lateral color of light with wavelengths of 470 nm, 555 nm and 650 nm after passing the camera optical lens  20  according to Embodiment 2.  FIG. 8  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 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 various conditions. 
     In this embodiment, the entrance pupil diameter of the camera optical lens is 1.897 mm. The image height of 1.0H is 3.284 mm. The FOV is 74.25°. 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 3 
     Embodiment 3 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. 
     Tables 9 and 10 show design data of a camera optical lens  30  in Embodiment 3 of the present invention.

       FIG. 10  and  FIG. 11  respectively illustrate a longitudinal aberration and a lateral color of light with wavelengths of 470 nm, 555 nm and 650 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 13 in the following lists values corresponding to the respective conditions in this embodiment in order to satisfy the above conditions. 
     In this embodiment, the entrance pupil diameter of the camera optical lens is 1.871 mm. The image height of 1.0H is 3.284 mm. The FOV is 73.64°. 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.
