A miniature image capture lens is disclosed, comprising a wafer scale lens system, which comprises a first lens group including a first substrate, a first surface disposed on a first side of the first substrate, a second surface disposed on a second side of the first substrate, and a second lens group including a second substrate, a third surface disposed on a first side of the second substrate, and a fourth surface disposed on a second side of the second substrate, wherein the first surface, the second surface, the third surface and the fourth surface are aspherical, one of the first surface and the second surface, and one of the third surface and the fourth surface have a high refraction index Nd_h and a high abbe number Vd_h, another one of the first surface and the second surface, and another one of the third surface and the fourth surface have a low refraction index Nd_1 and a low abbe number Vd_1, and the miniature image capture lens meets the following conditions:
Nd_h = 1.58ˆ¼1.62;
Nd_1 = 1.48ˆ¼1.53;
Nd_1/Nd_h = 0.91ˆ¼0.97;
Vd_h = 35ˆ¼45;
Vd_1 = 25ˆ¼35;
and
Vd_1 / Vd_h = 1.2-2.2,
wherein one of the first and second surfaces is convex shaped and another one of the first and second surfaces is concave shaped, and one of the third and fourth surfaces is convex shaped and another one of the third and fourth surfaces is concave shaped.
