Document Type and Number:
WIPO Patent Application WO/2020/103555
Kind Code:
A1
Abstract:
Provided are an optical imaging lens (100) and an imaging device, the optical imaging lens (100) sequentially from an object side to an imaging surface (S15) along the optical axis comprises: a first group (Q1), a diaphragm (ST), and a second group (Q2), wherein, the first group (Q1) has a negative optical power, the first group (Q1) sequentially comprises a biconcave first lens (L1) having a negative optical power and a biconvex second lens (L2) having a positive optical power from the object side to the imaging surface (S15); the second group (Q2) has a positive optical power, the second group (Q2) sequentially comprises a third lens (L3) having a positive optical power with the object side surface (S5) being convex and the image side surface (S6) being concave, a biconcave fourth lens (L4) having a negative optical power, a biconvex fifth lens (L5) having a positive optical power, and a sixth lens (L6) having a positive optical power with the object side surface (S10) being convex and the image side surface (S11) being concave from the object side to the imaging surface (S15), wherein, the fourth lens (L4) and the fifth lens (L5) form a bonded body having a positive optical power; the diaphragm (ST) is disposed between the first group (Q1) and the second group (Q2). The optical imaging lens (100) and imaging device can provide good imaging quality.
