Abstract:
The present 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 concave object-side surface; and a third lens element with negative refractive power having a concave image-side surface, at least one of the object-side and image-side surfaces thereof being aspheric. With the aforementioned arrangement of lens elements, the total track length of the optical imaging lens assembly can be effectively reduced, the sensitivity of the optical system can be attenuated, a large field of view can be achieved and the image quality can be improved.
