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 a positive refractive power; a second lens having a refractive power; a third lens having a refractive power; a fourth lens having a refractive power, a fifth lens having a refractive power, of which an image-side surface is a concave surface; a sixth lens having a refractive power; and a seventh lens having a negative refractive power. An effective focal length f of the optical imaging lens assembly and half of a maximal field-of-view angle HFOV of the optical imaging lens assembly satisfy: 5.5 mm<tan(HFOV)*f<6.5 mm. The optical imaging lens assembly of the present disclosure has at least one of the advantages of a large imaging plane, a large wide angle, a large aperture and ultra-thinness.
