Abstract

This invention provides an optical imaging lens assembly comprising, in order from an object side to an image side: a first lens element with positive refractive power having a convex object-side surface; a second lens element with negative refractive power having a convex object-side surface and a concave image-side surface; a third lens element having a convex image-side surface, the edge of the image-side surface of the third lens element within the clear aperture diameter tends to the image side; a fourth lens element with negative refractive power having a concave image-side surface; a first stop disposed between an object and the first lens element; and a second stop disposed between the second and fourth lens elements. With the aforementioned arrangement of optical lenses, the total track length of the optical imaging lens assembly can be reduced effectively, the sensitivity of the optical lens assembly can be attenuated, and the image quality can be improved.
