摘要

A miniature image capturing lens includes an aperture diaphragm; and a lens system consisting of a first lens having a positive refracting power in which a convex surface of the first lens is directed toward an image; and a meniscus-shaped second lens in which a concave surface of the meniscus is directed toward an object. The aperture diaphragm, the first lens and the second lens are aligned in this order from the object side, the fist and second lenses have at least one aspherical surface. The following conditional formulas are satisfied:;where f1 is a focal length of the first lens, f is a focal length of the entire image capturing lens, R1 is a radius of curvature of the object side surface of the first lens, and R2 is a radius of curvature of the image side surface of the second lens.
