Patent ID: 8314999

Claim:
An optical image lens assembly comprising, in order from an object side to an image side: a first lens element with positive refractive power, and having a convex object-side surface; a second lens element with negative refractive power; a third lens element with negative refractive power, and having a convex object-side surface and a concave image-side surface, wherein the third lens element is made of plastic material, and the object-side surface and the image-side surface of the third lens element are aspheric; and a fourth lens element with refractive power, and having a concave image-side surface, wherein the fourth lens element is made of plastic material, and the object-side surface and the image-side surface of the fourth lens element are aspheric; wherein an axial distance between the second lens element and the third lens element is T 23 , an axial distance between the third lens element and the fourth lens element is T 34 , a focal length of the optical image lens assembly is f, and a focal length of the third lens element is f 3 , the following relationships are satisfied: 0 <T 34 /T 23<1.5; and −1.3 <f/f 3<−0.36.
