Abstract
A micro-lens module including a first lens, a second lens, and an aperture stop is provided. The first lens is disposed between an object side and an image side, wherein a first surface of the first lens facing the object side is an aspheric surface, and the curvature radius of the aspheric surface is R. The second lens is disposed between the first lens and the image side, wherein a second surface of the second lens facing the image side is an aspheric surface, and the curvature radius of the aspheric surface is R. The aperture stop is disposed between the first lens and the second lens, wherein the distance from the first surface to the aperture stop is d, and the distance from the second surface to the aperture stop is d. The micro-lens module satisfies 6>d/d>2.5 and −2.5<R/R<1.5.
