Title:
CAMERA OPTICAL LENS
Document Type and Number:
WIPO Patent Application WO/2021/196256
Kind Code:
A1
Abstract:
Disclosed is a camera optical lens (10), sequentially comprising, from an object side to an image side, a first lens (L1) having a positive refractive power, a second lens (L2) having a negative refractive power, a third lens (L3) having a negative refractive power, a fourth lens (L4) having a positive refractive power, and a fifth lens (L5) having a negative refractive power, wherein the overall focal length of the optical camera lens (10) is f, the focal length of the first lens (L1) is f1, the focal length of the third lens (L3) is f3, the radius of curvature of the object side surface of the second lens (L2) is R3, the radius of curvature of the image side surface of the second lens (L2) is R4, the radius of curvature of the object side surface of the third lens (L3) is R5, the radius of curvature of the image side surface of the third lens (L3) is R6, the on-axis thickness of the third lens (L3) is d5, and the on-axis thickness of the fourth lens (L4) is d7, which satisfy the following relational expressions: 0.75 ≤ f1/f ≤ 0.95; -4.50 ≤ f3/f ≤ -3.00; 2.00 ≤ (R5+R6)/(R5-R6) ≤ 8.00; 3.00 ≤ d7/d5 ≤ 5.00; and -12.00 ≤ R3/R4 ≤ -2.50. The camera optical lens (10) also meets the design requirements of a large aperture, a wide angle and ultra-thinness while having an excellent optical performance.
