Abstract
Embodiments of the present disclosure provide an optical imaging lens assembly, which comprises, sequentially along an optical axis from an object side to an image side: a first lens, having a positive refractive power; a second lens, having a negative refractive power; a third lens, having a positive refractive power; a fourth lens, having a negative refractive power; a fifth lens, having a positive refractive power; a sixth lens, having a positive refractive power; and a seventh lens, having a negative refractive power. A total effective focal length f of the optical imaging lens assembly and half of a maximal field-of-view Semi-FOV of the optical imaging lens assembly satisfy: f×tan(Semi-FOV)≥5.0 mm; and a center thickness CT1 of the first lens on the optical axis and an edge thickness ET1 of the first lens satisfy: 1.5<CT1/ET1<2.0.
