Title:
CAMERA OPTICAL LENS
Document Type and Number:
WIPO Patent Application WO/2022/047979
Kind Code:
A1
Abstract:
A camera optical lens (10). The camera optical lens (10) comprises, from an object side to an image side: a first lens (L1) having positive refractive power; a second lens (L2) having positive refractive power; a third lens (L3) having positive refractive power; a fourth lens (L4) having negative refractive power; a fifth lens (L5) having negative refractive power; a sixth lens (L6) having positive refractive power; and a seventh lens (L7) having negative refractive power, wherein the focal length of the camera optical lens (10) is f, the focal length of the second lens (L2) is f2, the focal length of the seventh lens (L7) is f7, the central radius of curvature of the object side surface of the fifth lens (L5) is R9, the central radius of curvature of the image side surface of the fifth lens (L5) is R10, and the following relations are met: 1.50 ≤ f2/f ≤ 5.00, -9.50 ≤ (R9+R10)/(R9-R10) ≤ -1.20, and -2.00 ≤ f7/f ≤ -0.60. The camera optical lens (10) satisfies large-aperture, wide-angle, and ultra thin design requirements while having good optical performance.
