Title:
CAMERA OPTICAL LENS
Document Type and Number:
WIPO Patent Application WO/2022/052258
Kind Code:
A1
Abstract:
A camera optical lens (10), the camera optical lens (10) comprising six lenses in total. In order from the object side to the image side, the six lenses are: a first lens (L1) having positive refractive power, a second lens (L2) having negative refractive power, a third lens (L3) having negative refractive power, a fourth lens (L4) having positive refractive power, a fifth lens (L5) having negative refractive power, and a sixth lens (L6). The focal length of the camera optical lens (10) is f, the focal length of the second lens (L2) is f2, the radius of curvature of the center of the object side surface of the fifth lens (L5) is R9, the radius of curvature of the center of the image side surface of the fifth lens (L5) is R10 and the following relationships are satisfied: -5.00≤f2/f≤-2.00; and 3.00≤R9/R10≤20.00. The camera optical lens (10) satisfies design requirements for a large aperture, long focal length and ultra-thinness while having a good optical performance.
