Optical imaging lens assembly, image acquisition unit and electronic device

Abstract

Optical imaging lens assembly comprising eight lens elements (E1, E2, E3, E4, E5, E6, E7, E8), wherein the eight lens elements (E1, E2, E3, E4, E5, E6, E7, E8) are arranged in the order from an object side to an image side along a beam path as a first lens element (E1), a second lens element (E2), a third lens element (E3), a fourth lens element (E4), a fifth lens element (E5), a sixth lens element (E6), a seventh lens element (E7) and an eighth lens element (E8), and wherein each of the eight lens elements (E1, E2, E3, E4, E5, E6, E7, E8) has an object-side surface facing the object side and an image-side surface facing the image side;wherein the first lens element (E1) has a negative refractive power, the fourth lens element (E4) has a positive refractive power, the fifth lens element (E5) has a negative refractive power, the sixth lens element (E6) has a positive refractive power, the eighth lens element (E8) has a negative refractive power, and the object-side surface of the eighth lens element (E8) has at least one inflection point (P); wherein an axial distance between the object-side surface of the first lens element (E1) and the image-side surface of the eighth lens element (E8) is TD, a focal length of the optical imaging lens assembly is f, a central thickness of the third lens element (E3) is CT3, a central thickness of the seventh lens element (E7) is CT7, an axial distance between the seventh lens element (E7) and the eighth lens element (E8) is T78, and the following conditions are met: 3.00 <TD / CT3<7,00;3,50<TD / f<5,60; und0,10<CT7 / T78<0,60.;
