Title: Camera optical lens

Description:
TECHNICAL FIELD

     BACKGROUND 
     With the emergence of smart phones in recent years, the demand for miniature camera lens is continuously increasing, but in general, photosensitive devices of a camera lens are nothing more than a Charge Coupled Device (CCD) or a Complementary Metal-Oxide Semiconductor Sensor (CMOS sensor), and as progress of semiconductor manufacturing technology makes a pixel size of the photosensitive devices become smaller, in addition, a current development trend of electronic products requires better performance with 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, a camera lens traditionally equipped in a camera of a mobile phone generally constitutes three lenses. Although the common camera lens constituted by three lenses already has good optical performances, its configurations such as refractive power, lens spacing and lens shape still need to be optimized, therefore the camera lens may not meet design requirements on some optical performances such as large aperture, ultra-thinness and wide angle while maintaining good imaging quality.
