Abstract
An optical coupling lens includes a main portion and two reference portions. The main portion includes a first surface having at least one first converging lens formed thereon, a second surface having at least one second converging lenses formed thereon, and a reflecting surface. The second surface is substantially perpendicular to the first surface. An angle between the reflecting surface and the first surface is about 45 degrees. An optical axis of the first converging lens is substantially perpendicular to the first surface, and an optical axis of the second converging lens is substantially perpendicular to the second surface. Each reference portion includes a reference member. The reference member includes a reference point. A connecting line of the reference points of the reference portions is substantially parallel to the first surface and the second surface, and the connecting line is in a surface substantially coplanar with the reflecting surface.
