Abstract
The present disclosure relates to the technical field of optical lens and discloses a camera optical lens satisfying following conditions: 10.00<f4/f<31.00; 2.80<v3/v2<4.00; 1.60<n4<2.10; and 5.00<d5/d6<21.00; where f denotes a focal length of the camera optical lens; f4 denotes a focal length of the third lens; v2 denotes an abbe number of the first lens; v3 denotes an abbe number of the second lens; n4 denotes a refractive index of the d line of the third lens; d5 denotes an on-axis thickness of the second lens, and d6 denotes an on-axis distance from the image-side surface of the second lens to the object-side surface of the third lens. The camera optical lens in the present disclosure satisfies a design requirement of wide angle, large aperture and fingerprint recognition while having good optical performance.
