Patent ID: 11480771

Abstract:
The present invention relates to the technical field of optical lens and discloses a camera optical lens satisfying following conditions: −3.50≤f2/f≤−1.50, 6.50≤d1/d2≤13.50, −0.20≤(R9+R10)/(R9−R10)≤−0.05, and 3.00≤R6/f≤10.00; where f denotes a focal length of the camera optical lens, f2 a focal length of the second lens, d1 an on-axis thickness of the first lens, d2 an on-axis distance from an image-side surface of the first lens to an object-side surface of the second lens, R6 a curvature radius of an image-side surface of the third lens, R9 a curvature radius of an object-side surface of the fifth lens, and R10 a curvature radius of an image-side surface of the fifth lens. The camera optical lens in the present disclosure satisfies a design requirement of large aperture, ultra-thinness and wide angle while having good optical functions.
