Title:
OPTICAL IMAGING LENS
Document Type and Number:
WIPO Patent Application WO/2023/151456
Kind Code:
A1
Abstract:
An optical imaging lens (100). The optical imaging lens (100) sequentially comprises, from an object side to an image surface along an optical axis: a first lens (L1) having negative focal power, an object side surface (S1) of the first lens (L1) being a convex surface, and an image side surface (S2) of the first lens being a concave surface; a second lens (L2) having positive focal power, an image side surface (S4) of the second lens (L2) being a convex surface; a diaphragm (ST); a third lens (L3) having positive focal power, an object side surface (S5) and an image side surface (S6) of the third lens (L3) both being convex surfaces; a fourth lens (L4) having positive focal power, an object side surface (S7) and an image side surface (S8) of the fourth lens (L4) both being convex surfaces; and a fifth lens (L5) having negative focal power, an object side surface (S9) of the fifth lens (L5) being a concave surface, an image side surface (S10) of the fifth lens (L5) being a convex surface, and the fourth lens (L4) and the fifth lens (L5) constituting a cemented lens. The optical imaging lens (100) has advantages of being large in aperture, large in wide angle, small in volume, and high in resolution, and has a special form of distortion, such that the use requirements of an ADAS system can be satisfied better.
