Patent ID: 7796349

Claim:
A miniature image capture lens, comprising: an aperture diaphragm having an aperture through which an image is captured; and a wafer-level lens system, comprising: a first lens group, including: a first substrate; a first lens disposed on a first side of the first substrate; a second lens disposed on a second side of the first substrate a second lens group, including: a second substrate; a third lens disposed on a first side of the second substrate; a fourth lens disposed on a second side of the second substrate, wherein the first lens, the second lens, the third lens and the fourth lens are aspherical and the miniature image capture lens meets the following conditions: L/f e <1.6; f 1 /f e =0.5˜1.5; f 2 /f e =−1˜−3; T group2 /T BFL =0.8˜1.2; and T air /T group2 =0.4˜0.8, wherein L: total track length (TTL) from the first lens to an image plane, f e : effective focal length of whole lens system, f 1 : effective focal length of the first lens, f 2 : effective focal length of the second lens, T group2 : thickness of the second lens group, T air : distance between the second lens and the third lens, and T lens2 : thickness of the second lens, T lens2 : thickness of the second lens, and T BFL : back focal length from the last lens surface to the image plane.
