Patent attributes
The present application relates to the optical lens technical field and discloses a camera optical lens including, from an object side to an image side: an aperture, and a first, second, third, fourth and fifth lenses, each lens having, in sequence, a positive, negative, negative, positive and negative refractive power respectively. The camera optical lens satisfies following conditions: 1.00≤f1/f≤1.10; 0.40≤f4/f≤0.60; and 11.00≤R9/R10≤12.00; where mm denotes a unit of a focal length; f denotes a focal length of the camera optical lens; f1 denotes a focal length of the first lens; f4 denotes a focal length of the fourth lens; R9 denotes a curvature radius of an object-side surface of the fifth lens; and R10 denotes a curvature radius of an image-side surface of the fifth lens. The camera optical lens both has good optical performance and meets a design requirement of big aperture, ultra-thinness and wide angle.
