Abstract
A camera optical lens is provided, including from an object side to an image side: a first lens having positive refractive power; a second lens having negative refractive power; a third lens having positive refractive power; a fourth lens having negative refractive power; a fifth lens having positive refractive power; a sixth lens having negative refractive power; a seventh lens having positive refractive power; an eighth lens having positive refractive power; and a ninth lens having negative refractive power, wherein the camera optical lens satisfies following conditions: 2.20≤f1/f≤5.00; and 3.00≤d13/d14≤15.00. The above camera optical lens can meet design requirements for large aperture, wide angle and ultra-thinness, while maintaining good imaging quality.
