Abstract
An optical lens adapted to receive an image beam from an imaging element is provided. The optical lens sequentially includes a first lens, a second lens, a third lens, and a fourth lens with refracting power along an optical axis from a light incidence side to a light exit side, and the first lens to the fourth lens each include a light incidence surface facing the light incidence side and a light exit surface facing the light exit side. The first lens has positive refracting power. The second lens has negative refracting power. The third lens has positive refracting power. The first lens or the third lens is made of glass. The optical lens receives the image beam from the light incidence side. The image beam forms a stop on the light exit side, and the image beam forms the minimum beam cross-section at a location of the stop.
