Abstract

An optical imaging lens assembly is disclosed. The optical imaging lens assembly includes, sequentially along an optical axis from an object side to an image side, a first lens to a fifth lens. The first lens may have a positive refractive power and a concave object-side surface. The second lens may have a positive or a negative refractive power and a concave object-side surface. The third lens may have a positive or a negative refractive power. The fourth lens may have a positive refractive power and a convex image-side surface. The fifth lens may have a negative refractive power, and an object-side surface of the fifth lens and an image-side surface of the fifth lens may both be concave surfaces. 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: CT3/CT4≥1.5.
