Title:
OPTICAL IMAGING LENS
Document Type and Number:
WIPO Patent Application WO/2020/007081
Kind Code:
A1
Abstract:
An optical imaging lens, comprising sequentially from an object side to an image side along an optical axis: a first lens (E1), a second lens (E2), a third lens (E3), a fourth lens (E4), a fifth lens (E5), a sixth lens (E6) and a seventh lens (E7). The first lens (E1) has a positive focal power, the object side surface (S1) thereof being a convex surface; the second lens (E2) has a focal power, the image side surface (S4) thereof being a concave surface; the third lens (E3) has a focal power; the fourth lens (E4) has a focal power; the fifth lens (E5) has a focal power; the sixth lens (E6) has a focal power, the object side surface (S11) thereof being a concave surface, and the image side surface (S12) thereof being a convex surface; the seventh lens (E7) has a negative focal power, the object side surface (S13) thereof being a concave surface, and the image side surface (S14) thereof being a convex surface; and the distance T45 between the fourth lens (E4) and the fifth lens (E5) on the optical axis, the distance T56 between the fifth lens and the sixth lens on the optical axis, and the total effective focal length f of the optical imaging lens satisfy 0.5mm-1＜T45/(T56×f)＜2mm-1.
