Abstract:
A slim lens assembly in accordance with the invention in order from an object side to an image side along an optical axis, comprises a first lens, a second lens, a third lens and a fourth lens. The first lens is with positive refractive power, which includes a convex surface facing an image side. The second lens is with positive refractive power, which includes a concave surface facing the image side. The third lens is with positive refractive power, which includes a concave surface facing the object side and a convex surface facing the image side. The fourth lens is with positive refractive power.

Claim (Index 4):
The slim lens assembly according to  claim 1 , wherein a composite focal length of the second lens element, the third element and the fourth element is f 234 , the focal length of the first lens element is f 1 , the focal length of the second lens element is f 2 , the focal length of the third lens element is f 3 , the focal length of the fourth lens element is f 4 , a radius of curvature of the image-side surface of the first lens is R 12  and they satisfy the relations: 0<f 234 /f 4 <1, 0<(f 1 +f 3 )/(f 2 +f 4 )<10, R 12 /f 1 <0.
