Abstract

The present disclosure discloses an optical imaging lens assembly including, sequentially from an object side to an image side along an optical axis, a first lens having positive refractive power; a second lens having refractive power; a third lens having positive refractive power with a concave object-side surface and a convex image-side surface; a fourth lens having positive refractive power with a concave object-side surface and a convex image-side surface; and a fifth lens having refractive power. Half of a maximal field-of-view Semi-FOV of the optical imaging lens assembly satisfies: Semi-FOV>48°.
