Abstract

An optical imaging lens assembly is provided. The optical imaging lens includes a first lens (E1), a second lens (E2), a third lens (E3), a fourth lens (E4), a fifth lens (E5), a sixth lens (E6) and a seventh lens (E7) which are provided in sequence from an object side to an image side along an optical axis and have refractive powers. The first lens has a positive refractive power. The fourth lens has a positive refractive power. The sixth lens has a negative refractive power. The seventh lens has a negative refractive power. An object-side surface (S7) of the fourth lens is a concave surface, and an image-side surface (S8) is a convex surface. An object-side surface (S9) of the fifth lens is a convex surface.
