Description

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 constantly increasing. However, the photosensitive devices of camera lens are generally limited to Charge Coupled Device (CCD) or Complementary Metal-Oxide Semiconductor Sensor (CMOS sensor). In addition, with the advance of the semiconductor manufacturing technology, the pixel size of the photosensitive devices become smaller, accompanying with 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 conventionally equipped in mobile phone cameras adopts a three-piece or four-piece lens structure. Also, with the development of technology and the increasingly diverse demands of users, the pixel area of photosensitive devices is becoming smaller and smaller and the requirement of the system on the imaging quality is increasingly higher, such that a six-piece lens structure gradually emerges in lens designs. Therefore, it is urgent to provide a wide-angle camera lens with excellent optical characteristics, ultra-thin and fully corrected chromatic aberrations.
