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 having a positive refractive power; a second lens having a negative refractive power; a third lens having a refractive power; a fourth lens having a refractive power and an image-side surface of the fourth lens being a concave surface; and a fifth lens having a refractive power. ImgH, half of a diagonal length of an effective pixel region on an imaging surface of the optical imaging lens assembly, TTL, a distance from an object-side surface of the first lens to the imaging surface on the optical axis, and f, a total effective focal length of the optical imaging lens assembly satisfy: ImgH/(TTL/f)>45 mm, which makes the optical imaging lens assembly have the features of long focus, a large image surface, etc.
