OPTICAL LENS

WIPO Patent Application WO/2024/067253

A1

An optical lens, comprising seven lenses in total, which are sequentially from an object side to an imaging surface along an optical axis: a first lens (L1) having negative focal power, an object side surface (S1) and an image side surface (S2) thereof both being concave surfaces; a second lens (L2) having positive focal power, an object side surface (S3) and an image side surface (S4) thereof both being convex surfaces; a diaphragm (ST); a third lens (L3) having positive focal power, an object side surface (S5) thereof being a concave surface, and an image side surface (S6) thereof being a convex surface; a fourth lens (L4) having positive focal power, an image side surface (S8) thereof being a convex surface; a fifth lens (L5) having negative focal power, an object side surface (S9) thereof being a concave surface, and an image side surface (S10) thereof being a convex surface; a sixth lens (L6) having focal power, an object side surface (S11) thereof being a concave surface, and an image side surface (S12) being a convex surface; and a seventh lens (L7) having focal power, an object side surface (S13) thereof being a convex surface, and an image side surface (S14) thereof being a concave surface. The total optical length TTL and an effective focal length f of the optical lens satisfy: TTL/f < 5.0. The optical lens has the advantages of large field of view, large aperture and miniaturization.
