摘要： A lens module (10) for image capture comprises a first positive meniscus lens (16) having a focal length F1 and comprising a first convex optical surface (18) facing the object side (12), and a second concave optical surface (20) facing the image side (14), and a second positive meniscus lens (22) having a focal length F2 and comprising a third concave optical surface (24) facing the object side (12), and a fourth convex optical surface (26) facing the image side (14). The four surfaces follow the equations: Zi=CURViYi2/(1+(1−(1−Ki)CURVi2Yi2)1/2)+(Ai)Yi2+(Bi)Yi4+(Ci)Yi6+(Di)Yi8 and Mi=1−(1+Ki)(CURVi)2(Ri)2 wherein: i is the surface number, Ki is the conic constant of the i-th surface, CURVi is the curvature of the i-th surface at the optical axis, Ai, Bi, Ci, and Di are aspheric coefficients of the i-th surface, and Ri is the effective radius of the aperture of the i-th surface. The following relations can be satisfied: 0.70
