Document Type and Number:
WIPO Patent Application WO/2021/134270
Kind Code:
A1
Abstract:
A camera optical lens (10), sequentially comprising, from an object side to an image side, a first lens (L1), a second lens (L2), a third lens (L3), a fourth lens (L4) and a fifth lens (L5); at least one of the first lens (L1) to the fifth lens (L5) has a free-form surface, the focal length of the first lens (L1) is f1, the focal length of the second lens (L2) is f2, the focal length of the third lens (L3) is f3, and the radius of curvature of an image side surface of the second lens (L2) is R4, and the following relational expressions are satisfied: f1 ≥ 0.00; f2 ≥ 0.00; f3 ≤ 0.00; and R4 ≤ 0.00. Such a camera optical lens is ultra-thin and wide-angle, and has good optical performance; in addition, as there is at least one lens having a free-form surface, aberration can be effectively corrected, further improving the performance of an optical system.
