Patent ID: 11668900

Abstract:
A camera optical lens includes a first lens to a fifth lens. The camera optical lens satisfies 1.80≤f1/f≤3.50; 1.25≤d7/d9≤1.80; 0.40≤f4/f≤0.90; 3.50≤R9/R10≤7.50; and 1.00≤R3/R4≤2.00, where f denotes an total focal length of the camera optical lens, f1 denotes a focal length of the first lens, f4 denotes a focal length of a fourth lens, R3 denotes a curvature radius of an object side surface of a second lens, R4 denotes a curvature radius of an image side surface of the second lens, R9 denotes a curvature radius of an object side surface of the fifth lens, R10 denotes a curvature radius of an image side surface of the fifth lens, d7 denotes an on-axis thickness of the fourth lens, and d9 denotes an on-axis thickness of the fifth lens. The camera optical lens meets design requirements of a large aperture, a wide angle, and ultra-thinness while having good optical performance.
