Title:
CAMERA OPTICAL LENS
Document Type and Number:
WIPO Patent Application WO/2021/128275
Kind Code:
A1
Abstract:
A camera optical lens (10, 20, 30), 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 maximum field-of-view angle of the camera optical lens (10, 20, 30) is FOV, the focal length of the fifth lens L5 is f5, the focal length of the sixth lens L6 is f6, 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, and the following relational expressions are satisfied: 100.00° ≤ FOV ≤ 135.00°; -10.00 ≤ f5/f6 ≤ -1.00; and 1.00 ≤ R5/R6 ≤ 20.00. The camera optical lens (10, 20, 30) can obtain low TTL while obtaining a high imaging performance.
