Document Type and Number:
WIPO Patent Application WO/2021/127879
Kind Code:
A1
Abstract:
Disclosed is a camera optimal lens, sequentially containing, from an object side to an image side: a first lens (L1), a second lens (L2), a third lens (L3), a fourth lens (L4), a fifth lens (L5), a sixth lens (L6), a seventh lens (L7), and an eighth lens (L8), wherein the focal length of the camera optical lens (10) is f, the focal length of the first lens (L1) is f1, the focal length of the second lens (L2) is f2, the radius of curvature of the object side surface of the fifth lens (L5) is R9, the radius of curvature of the image side surface of the fifth lens (L5) is R10, the on-axis thickness of the fourth lens (L4) is d7, and the on-axis distance from the image side surface of the fourth lens (L4) to the object side surface of the fifth lens (L5) is d8, which satisfy the following relational expressions: 0.92 ≤ f1/f ≤ 1.90; f2 ≤ 0; -0.90 ≤ (R9 + R10)/(R9 - R10) ≤ -0.10; and 2.50 ≤ d7/d8 ≤ 20.00. The camera optical lens (10) has a large aperture, a wide angle, ultra-thinness, etc., and has a good optical performance.
