Title:
IMAGING OPTICAL LENS
Document Type and Number:
WIPO Patent Application WO/2021/128150
Kind Code:
A1
Abstract:
Provided is an imaging optical lens (10), which sequentially comprises from the object side to the image side: a first lens (L1) with negative refractive power, a second lens (L2) with negative refractive power, and a third lens (L3) with positive refractive power, a fourth lens (L4) with positive refractive power, a fifth lens (L5), a sixth lens (L6), and a seventh lens (L7); the focal length of the imaging optical lens (10) is f, the on-axis thickness of the first lens (L1) is d1, the on-axis thickness of the second lens (L2) is d3, the on-axis thickness of the third lens (L3) is d5, and the on-axis thickness of the fifth lens (L5) is d9, the radius of curvature of the object side of the third lens (L3) is R5, the radius of curvature of the image side of the third lens (L3) is R6, and the maximum field of view of the imaging optical lens (10) is FOV, meeting the following relationship: 100.00°≤FOV≤135.00°; 2.00≤(d1+d5)/d3≤4.00; 0.50≤(R5+R6)/(R5-R6)≤10.00; 0.05≤d9/f≤0.20. The imaging optical lens (10) can obtain high imaging performance while obtaining low TTL.
