     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 the photosensitive devices of general camera lens are no other 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 shrink, coupled with the current development trend of electronic products being that their functions should be better and their shape should be thin and small, miniature camera lens with good imaging quality therefor has 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. And, with the development of technology and the increase of the diverse demands of users, and under this circumstances that the pixel area of photosensitive devices is shrinking steadily and the requirement of the system for the imaging quality is improving constantly, the five-piece, six-piece and seven-piece lens structure gradually appear in lens design. There is an urgent need for ultra-thin wide-angle camera lenses which have good optical characteristics and the chromatic aberration of which is fully corrected.

       FIG. 10  and  FIG. 11  show the longitudinal aberration and lateral color schematic diagrams after light with a wavelength of 470.0 nm, 555.0 nm and 650.0 nm passes the camera optical lens  30  in the third embodiment.  FIG. 12  shows the field curvature and distortion schematic diagrams after light with a wavelength of 555.0 nm passes the camera optical lens  30  in the third embodiment. 
     As shown in Table 13, the third embodiment satisfies the various conditions. 
     In this embodiment, the pupil entering diameter of the camera optical lens is 1.691 mm, the full vision field image height is 2.933 mm, the vision field angle in the diagonal direction is 81.78°, it has wide-angle and is ultra-thin, its on-axis and off-axis chromatic aberrations are fully corrected, and it has excellent optical characteristics.
