Abstract
An optical coupling lens includes an incident surface, a first total reflection surface, a second total reflection surface and an emergent surface orderly connected to each other end to end. The incident surface includes a first lens portion and a second lens portion thereon. The emergent surface includes a third lens portion thereon. The third lens portion is positioned adjacent to the second total reflection surface. The first lens portion converges incident light into a parallel light beam. The first total reflection surface reflects the light beam to an intersection between the second total reflection surface and the emergent surface. The third lens portion directs the portion of the light beam to an optical fiber. The second total reflection surface reflects the other portion of the light beam to the second lens portion. The second lens portion directs the other portion of the light beam to an optical detector.
