Document Type and Number:
WIPO Patent Application WO/2020/164236
Kind Code:
A1
Abstract:
An optical imaging lens, successively comprising 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) and a fifth lens (E5) having focal power. The first lens (E1) has positive focal power, an object side surface (S1) thereof is convex and an image side surface (S2) thereof is convex; the second lens (E2) has a negative focal power, an object side surface (S3) thereof is convex and an image side surface (S4) thereof is concave; the distance TTL between the object side surface (S1) of the first lens (E1) and an imaging plane (S13) of the optical imaging lens on the optical axis and the total effective focal length f of the optical imaging lens satisfy TTL/f≤1.0; and the aperture number Fno of the optical imaging lens satisfies Fno<2.0.
