Document Type and Number:
WIPO Patent Application WO/2018/223616
Kind Code:
A1
Abstract:
Provided is an imaging lens, having a total effective focal length f and comprising a first lens (E1), a second lens (E2), a third lens (E3), a fourth lens (E4), a fifth lens (E5), and a sixth lens (E6) sequentially from an object side to an image side along an optical axis. The first lens (E1) has a positive focal power, and an object side surface (S1) thereof is a convex surface. The second lens (E2) has a negative focal power. The third lens (E3), the fourth lens (E4), the fifth lens (E5), and the sixth lens (E6) all have a positive or negative focal power. A distance TTL along the optical axis from the object side surface (S1) of the first lens (E1) to an imaging surface (S15) of the imaging lens and the total effective focal length f of the imaging lens satisfies TTL / f ≤ 1.05.
