Abstract

The disclosure provides an optical imaging lens assembly, which includes nine lenses. From an object side to an image side, the nine lenses are sequentially: a first lens with positive refractive power, a second lens with positive refractive power, of which an object-side surface thereof is a convex surface while an image-side surface is a concave surface, a third lens with refractive power, of which an object-side surface thereof is a convex surface while an image-side surface is a concave surface, a fourth lens with refractive power, a fifth lens with refractive power, a sixth lens with refractive power, a seventh lens with positive refractive power, an eighth lens with refractive power, and a ninth lens with negative refractive power. The nine lenses are independent of one another and have air spaces on an optical axis.
