Abstract
An optical coupling lens includes a light incident surface, a light output surface perpendicular to the light incident surface, a reflection surface interconnected between the light incident surface and the light output surface, a first converging lens and a second converging lens formed on the light incident surface, and third converging lens formed on the light output surface and has a semi-cylindrical shape. Optical axes of the first converging lens and the second converging lens are perpendicular to the light incident surface and located on a common imaginary plane. A central axial plane of the third converging lens is perpendicular to the light output surface. An intersecting line between the central axial plane and the common imaginary plane is located on the reflection surface. A width of the third converging lens is equal to a diameter of each of the first converging lens and the second converging lens.
