Abstract
The present disclosure discloses an imaging lens assembly, along an optical axis from an object side to an imaging side including sequentially a first lens assembly and a second lens assembly. The first lens assembly has a positive refractive power and along the optical axis from the object side to the imaging side includes sequentially: a first lens, having a positive refractive power and its object-side surface is convex; a second lens, having a negative refractive power; and a third lens, having a positive refractive power or a negative refractive power. The second lens assembly has a negative refractive power and along the optical axis from the object side to the imaging side sequentially includes: a fourth lens, having a negative refractive power; and a fifth lens, having a positive refractive power or a negative refractive power and its object-side surface is convex at a paraxial position.
