Title:
CAMERA OPTICAL LENS
Document Type and Number:
WIPO Patent Application WO/2022/007029
Kind Code:
A1
Abstract:
A camera optical lens (10). The camera optical lens sequentially comprises, from an object side to an image side: a first lens (L1) with a negative refractive power, a second lens (L2) with a positive refractive power, a third lens (L3) with a positive refractive power, a fourth lens (L4) with a positive refractive power, and a fifth lens (L5) with a negative refractive power. A focal length of the whole photographing optical lens (10) is f, a focal length of the third lens (L3) is f3, a radius of curvature of an object-side surface of the second lens (L2) is R3, a radius of curvature of an image-side surface of the second lens (L2) is R4, an on-axis thickness of the first lens (L1) is d1, an on-axis distance from an image-side surface of the first lens (L1) to the object-side surface of the second lens (L2) is d2, and the following relational expressions are satisfied: 2.50 ≤ f3/f ≤ 6.00; -2.00 ≤ R4/R3 ≤ -1.00; and 1.00 ≤ d1/d2 ≤ 1.80. The camera optical lens (10) exhibits good optical performances, and also meets the design requirements of a large aperture, a wide angle and ultra-thinness.
