Abstract

A miniature image pick-up lens system includes an aperture stop; a first lens; and a meniscus-shaped second lens having a concave surface on a side of an object. The stop, the first lens and the second lens are aligned in that order from the object side to an image side. The first lens has positive refractive power and has a convex surface formed with a grating structure on a side of the image, and an aspherical surface on the side of the object. The second lens has at least one aspheric surface. The two lenses are made of a same optical plastic. The system satisfies the following condition: (1) 1.4 < T/f < 1.7; wherein f indicates a focal length of all system, and T indicates a length from the aperture stop to the image pick-up surface.
