Abstract:
1. A compact 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 and a convex image-side surface, the object-side and image-side surfaces thereof being aspheric; and a second lens element with negative refractive power having a concave object-side surface and a concave image-side surface, at least one of the object-side and image-side surfaces thereof being aspheric, an air distance between itself and the first lens element; and wherein the compact imaging lens assembly further comprises an aperture stop and an electronic sensor for image formation; wherein the aperture stop is disposed between an imaged object and the first lens element, the electronic sensor is disposed at the image plane; wherein there are two lens elements with refractive power in the compact imaging lens assembly, a distance on the optical axis between the aperture stop and the electronic sensor is SL, a distance on the optical axis between the object-side surface of the first lens element and the electronic sensor is TTL, a radius of curvature on the object-side surface of the second lens element is R
