ABSTRACT:
The present invention relates to an optical coupling lens and light source module. An optical coupling lens is provided for converging a light flux emitted from a light source to an entrance aperture. The optical coupling lens satisfies a predetermined condition according to a third-order astigmatisms coefficient of the optical coupling lens. A light source module includes: a light source; an optical waveguide; and an optical unit including one or more of an optical coupling lens for converging a light flux emitted from the light source onto the optical waveguide. At least one optical coupling lens satisfies predetermined condition according to a third-order astigmatism coefficient of the optical coupling lens.
