Abstract
A lens includes a light incident surface and a light output surface. In a coordinate system, the light incident surface satisfies a formula (1): cis a curvature of the light incident surface. ris a distance from the center of the lens to a joint point between the light input surface and a radius which is substantially perpendicular to the central axis of the lens. uis a normalized radius of the light incident surface. arepresents the aspheric coefficient. Qis a polynomial of order m and represents that the sum of ais equal to the sum of the root mean square of the slope of the light incident surface. The light output surface satisfies a formula (2):
