Document Type and Number:
WIPO Patent Application WO/2021/128238
Kind Code:
A1
Abstract:
Disclosed is a camera optical lens (10), relating to the field of optical lenses. The camera optical lens (10) sequentially includes, 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 radius of curvature of an object side surface of the third lens (L3) is R5, the radius of curvature of an image side surface of the third lens (L3) is R6, the axial distance from the image side surface of the third lens (L3) to an object side surface of the fourth lens (L4) is d6, the axial distance from an image side surface of the fourth lens (L4) to an object side surface of the fifth lens (L5) is d8, the maximum field-of-view angle of the camera optical lens (10) is FOV, and the following relational expressions are satisfied: 100.00° ≤ FOV ≤ 135.00°; 1.00 ≤ R5/R6 ≤ 20.00; and 1.00 ≤ d6/d8 ≤ 5.00. The camera optical lens (10) can obtain low TTL while obtaining a high imaging performance.
