Abstract

The present disclosure provides an optical imaging lens assembly, the optical imaging lens assembly sequentially includes, along an optical axis from an object side to an image side: a first lens having a refractive power, where an object-side surface thereof is a concave surface and an image-side surface thereof is a convex surface; a second lens having a 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 refractive power, where an object-side surface thereof is a convex surface and an image-side surface thereof is a concave surface; and a seventh lens having a negative refractive power.

Dependent claims

An optical imaging lens assembly comprising, along an optical axis from an object side to an image side sequentially:

a first lens having a refractive power, wherein an object-side surface thereof is concave in a paraxial region thereof and an image-side surface thereof is convex in a paraxial region thereof;
a second lens having a 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 refractive power, wherein an object-side surface thereof is convex—in a paraxial region thereof, and an image-side surface thereof is concave in a paraxial region thereof;
and
a seventh lens having a negative refractive power,
wherein half of a diagonal length ImgH of an effective pixel area on an image plane of the optical imaging lens assembly satisfies:
6.0 mm<ImgH<7.0 mm.
