Abstract:
1. An optical image 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 refractive power; a third lens element with refractive power made of plastic material, wherein an object-side surface and an image-side surface of the third lens element are aspheric; and a fourth lens element with negative refractive power made of plastic material, and having a concave image-side surface, wherein an object-side surface and the image-side surface of the fourth lens element are aspheric, and the fourth lens element has at least one inflection point formed on at least one of the object-side surface and the image-side surface thereof; wherein the Abbe number of the first lens element is V1, the Abbe number of the second lens element is V2, the Abbe number of the third lens element is V3, the Abbe number of the fourth lens element is V4, a focal length of the optical image lens assembly is f, a focal length of the first lens element is f1, and the following relationships are satisfied:
