Patent ID: 7688531

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, including: a first surface disposed on a first substrate; a second substrate with a first side bonded to the first substrate; a second surface disposed on a second side of the second substrate; and a third surface disposed on a third substrate, wherein the first surface, the second surface and the third surface are aspherical and the following conditions are satisfied: L/f e <1.7; f 1 /f e =0.5˜1.5; f 2 /f e =−1˜−1.5; and −2 <f 3 /f e <2, wherein L: total track length (TTL) from the first surface to an image plane, f e : effective focal length of whole lens system, f 1 : effective focal length of the first surface, f 2 : effective focal length of the second surface, and f 3 : effective focal length of the third surface.
