Title:
CAMERA OPTICAL LENS
Document Type and Number:
WIPO Patent Application WO/2022/047980
Kind Code:
A1
Abstract:
A camera optical lens (10, 20, 30). The camera optical lens (10, 20, 30), from an object side to an image side, comprises: a first lens (L1) having negative refractive power, a second lens (L2) having positive refractive power, a third lens (L3) having negative refractive power, a fourth lens (L4) having positive refractive power, and a fifth lens (L5) having negative refractive power. The overall focal length of the camera optical lens (10, 20, 30) is f, the focal length of the first lens (L1) is f1, the focal length of the second lens (L2) is f2, the focal length of the third lens (L3) is f3, the on-axis thickness of the second lens (L2) is d3, the on-axis distance from an image side surface of the second lens (L2) to an object side surface of the third lens (L3) is d4, the center curvature radius of an object side surface of the fourth lens (L4) is R7, and the center curvature radius of an image side surface of the fourth lens (L4) is R8. The following relational expressions are satisfied: -3.00≤f1/f2≤-1.50; 1.80≤d3/d4≤4.00; 2.50≤R7/R8≤6.00; and f3/f≤-5.00. The camera optical lens (10, 20, 30) has good optical properties, and satisfies the design requirements of large aperture, wide angle, and ultra-thinness.
