Document Type and Number:

WIPO Patent Application WO/2021/128236

Kind Code:

A1

Abstract:

A camera optical lens (10, 20, 30, 40, 50), sequentially including, from an object side to an image side: a first lens (L1) having a negative refractive power, a second lens (L2) having a positive refractive power, a third lens (L3) having a positive refractive power, a fourth lens (L4) having a negative refractive power, a fifth lens (L5) having a positive refractive power, and a sixth lens (L6) having a negative refractive power, wherein the focal length of the camera optical lens (10, 20, 30, 40, 50) is f, the focal length of the first lens (L1) is f1, the radius of curvature of an object side surface of the sixth lens (L6) is R11, the radius of curvature of an image side surface of the sixth lens (L6) is R12, the axial distance from an image side surface of the first lens (L1) to an object side surface of the second lens (L2) is d2, the axial distance from an image side surface of the second lens (L2) to an object side surface of the third lens (L3) is d4, the maximum field-of-view angle of the camera optical lens (10, 20, 30, 40, 50) is FOV, and the following relational expressions are satisfied: 100.00° ≤ FOV ≤ 135.00°; 3.00 ≤ R11/R12 ≤ 20.00; 0.30 ≤ d2/d4 ≤ 1.00; and -3.00 ≤ f1/f ≤ -1.80. The camera optical lens (10, 20, 30, 40, 50) can obtain low TTL while obtaining a high imaging performance.
