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, a second lens, a third lens, a fourth lens, a fifth lens, and a sixth lens with a refractive power respectively; a center thickness CT3 of the third lens on the optical axis and a center thickness CT4 of the fourth lens on the optical axis satisfy 1.0≤CT4/CT3<1.5; and a spacing distance T34 between the third lens and the fourth lens on the optical axis and a spacing distance T45 between the fourth lens and the fifth lens on the optical axis satisfy 4.0<T34/T45<15.5.
