Title:
CAMERA OPTICAL LENS
Document Type and Number:
WIPO Patent Application WO/2021/128143
Kind Code:
A1
Abstract:
A camera optical lens (10, 20, 30, 40, 50), comprising, in order from an object side to an image side: a first lens (L1) having negative refraction power, a second lens (L2) having positive refraction power, a third lens (L3) having positive refraction power, a fourth lens (L4) having negative refraction power, a fifth lens (L5), a sixth lens (L6), and a seventh lens (L7). The maximum angle of field of view of the camera optical lens (10, 20, 30, 40, 50) is FOV, the focal length of the fourth lens (L4) is f4, the focal length of the camera optical lens (10, 20, 30, 40, 50) is f, the radius of curvature of the object side surface of the sixth lens (L6) is R11, the radius of curvature of the image side surface of the sixth lens (L6) is R12, and the following relational expressions are satisfied: 100.00°≤FOV≤135.00°; -5.00≤f4/f≤-2.00; and -20≤R11/R12≤-2.00. The camera optical lens (10, 20, 30, 40, 50) not only has good optical performance, but also meets wide-angle and ultrathin design requirements.
