Abstract:
1. An optical imaging lens assembly, comprising five non-cemented lenses with refractive power, sequentially arranged from an object side to an image side comprising: a first lens element with positive refractive power; a second lens element with negative refractive power; a third lens element with refractive power having a concave object-side surface, and at least one of the object-side surface and an image-side surface thereof being aspheric; a plastic fourth lens element with positive refractive power having both apsheric object-side surface and image-side surface; and a plastic fifth lens element with negative refractive power having a concave object-side surface and a convex image-side surface, and both object-side surface and image-side surface thereof being aspheric; wherein f is a focal length of the optical imaging lens assembly, f
