Abstract
The disclosure provides an optical imaging lens assembly, which sequentially includes, from an object side to an image side along an optical axis: a first lens with a negative refractive power; a second lens with a refractive power, an image-side surface thereof being a convex surface; a third lens with a refractive power, an object-side surface thereof being a convex surface; and a fourth lens with a negative refractive power, an object-side surface thereof being a convex surface while an image-side surface being a concave surface. ImgH is a half of a diagonal length of an effective pixel region on an imaging surface of the optical imaging lens assembly, and a spacing distance Tof the first lens and the second lens on the optical axis, a spacing distance Tof the second lens and the third lens on the optical axis and ImgH satisfy: 0.4<(T+T)/ImgH<0.6.
