Title:
OPTICAL IMAGING LENS AND IMAGING DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/116241
Kind Code:
A1
Abstract:
An optical imaging lens (100) and an imaging device (400). The optical imaging lens (100) sequentially comprises from an object side to an imaging surface along an optical axis: a first lens (L1) having a negative focal power, an object side surface (S1) and an image side surface (S2) thereof being both concave surfaces; a second lens (L2) having a positive focal power, an object side surface (S3) thereof being a concave surface, and an image side surface (S4) being a convex surface; an aperture (ST); a third lens (L3) having a positive focal power, an object side surface (S5) and an image side surface (S6) thereof being both convex surfaces; a fourth lens (L4) having a negative focal power, an object side surface (S7) thereof being a convex surface, and an image side surface (S8) being a concave surface; a fifth lens (L5) having a positive focal power, an object side surface (S8) and an image side surface (S9) thereof being both convex surfaces; and a sixth lens (L6) having a focal power, an image side surface (S10) thereof being a convex surface near the optical axis, and an image side surface (S11) being a concave surface near the optical axis, wherein the optical imaging lens (100) comprises at least one aspherical lens and a spherical lens. The optical imaging lens (100) has advantages of large aperture, high resolution, good thermal stability, and small diameter.
