WIPO Patent Application WO/2021/114234
Kind Code:
A1
Abstract:
Disclosed is a photographing optical lens (10), sequentially comprising, from an object side to an image side, a first lens (L1) with a positive refractive power, a second lens (L2) with a negative refractive power, a third lens (L3) with a negative refractive power, a fourth lens (L4), a fifth lens (L5), a sixth lens (L6) with a positive refractive power, and a seventh lens (L7) with a negative refractive power, wherein the focal length of the photographing optical lens (10) is f, the focal length of the third lens (L3) is f3, the Abbe number of the first lens (L1) is v1, and the Abbe number of the second lens (L2) is v2, which satisfy the following relational expressions: 2.80 ≤ v1/v2 ≤ 4.50; and -10.00 ≤ f3/f ≤ -3.00. The photographing optical lens (10) has a good optical performance, and meets the requirements of a large-aperture, wide-angle and ultra-thin design.
