Abstract

An embodiment of the present 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 and a fifth lens with refractive power. The first lens has a positive refractive power, the fourth lens has a positive refractive power, and the fifth lens has a negative refractive power. An abbe number V1 of the first lens and an abbe number V2 of the second lens satisfy the following relationship 45<|V1−V2|<70.
