CAMERA OPTICAL LENS
Document Type and Number:
WIPO Patent Application WO/2021/031239
Kind Code:
A1
Abstract:
The present invention provides a camera optical lens. The camera optical lens sequentially comprises, from an object side to an image side: a first lens, a second lens, a third lens, a fourth lens and a fifth lens; the focal length of the camera optical lens is f, the focal length of the first lens is f1, the focal length of the second lens is f2, the focal length of the third lens is f3, the focal length of the fifth lens is f5, the radius of curvature of an object side-surface of the second lens is R3, the radius of curvature of an image side-surface of the second lens is R4, the radius of curvature of an object-side surface of the fourth lens is R7, the radius of curvature of an image-side surface of the fourth lens is R8, the radius of curvature of an object-side surface of the fifth lens is R9, and the radius of curvature of an image-side surface of the fifth lens is R10, and the following relational expressions are satisfied: -0.50≤f1/f2≤-0.35; 5.00≤f3/f≤14.00; -3.10≤(f2+f5)/f≤-2.40; 3.00≤(R3+R4)/(R3-R4)≤4.00; 1.20≤(R7+R8)/(R7-R8)≤1.30; and 0.25≤(R9+R10)/(R9-R10)≤0.65.
