Abstract

The present disclosure relates to the technical field of optical lenses, and discloses a camera optical lens. The camera optical lens includes six lenses. An order of the six lenses are sequentially from an object side to an image side, which is shown as follows: a first lens having a negative refractive power, and a second lens having a positive refractive power, a third lens having a positive refractive power, a fourth lens having a negative refractive power, a fifth lens having a positive refractive power, and a sixth lens having a negative refractive power. The camera optical lens provided by the present disclosure has excellent optical characteristics, and further has characteristics of large aperture, wide-angle, and ultra-thin, especially suitable for mobile phone camera lens assemblies and WEB camera lenses, which are composed of camera components having high pixels, such as CCD and CMOS.
