Abstract
A lens module () for image capture comprises a first positive meniscus lens () having a focal length Fand comprising a first convex optical surface () facing the object side (), and a second concave optical surface () facing the image side (), and a second positive meniscus lens () having a focal length Fand comprising a third concave optical surface () facing the object side (), and a fourth convex optical surface () facing the image side (). The four surfaces follow the equations: Zi=CURViYi/(1+(1−(1−Ki)CURViYi))+(Ai)Yi+(Bi)Yi+(Ci)Yi+(Di)Yiand Mi=1−(1+Ki)(CURVi)(Ri)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<F/F<1.30 5<M/M<15.
