摘要:
Provided is a lens module for imaging an object on an image plane. In the order from the object side to the image side of the lens module, the lens module includes a first lens made of glass and having positive refraction power, a second lens made of plastic and having negative refraction power, a aperture stopper, a third lens having positive refraction power, and a fourth lens having negative refraction power. The lens module satisfies the following formula: Vd1−Vd2≧35; wherein, Vd1 is the Abbe number of the first lens in d light and Vd2 is the Abbe number of the second lens in the d light.
