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 and a concave image-side surface; a second lens having refractive power and a concave image-side surface; a third lens having refractive power; a fourth lens having refractive power; a fifth lens having positive refractive power; a sixth lens having refractive power, a convex object-side surface and a concave image-side surface; and a seventh lens having refractive power and a concave object-side surface. Half of a maximum field-of-view HFOV of the optical imaging lens assembly and a total effective focal length f of the optical imaging lens assembly satisfy: tan(HFOV)*f≥4.34 mm.
