Abstract

The present disclosure discloses an optical imaging lens assembly including, sequentially from an object side to an image side along an optical axis, a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens, a seventh lens, and an eighth lens having refractive power. A center thickness CT6 of the sixth lens along the optical axis and a spaced interval T56 between the fifth lens and the sixth lens along the optical axis satisfy: 1.5<CT6/T56<2.6. A relative F number Fno of the optical imaging lens assembly satisfies: Fno≤1.7.
