Abstract
An optical coupling lens includes main section, beam splitting section, first lens, second lens and third lens. A first groove is formed in the main section. A second groove is formed in the first groove. The beam splitting section includes a first total reflecting surface and a second total reflecting surface. A dihedral-angle between the first total reflecting surface and the second total reflecting surface is predetermined. The first lens is defined in the first groove. The first lens includes a beam splitter. The beam splitter includes a first light emitting surface. The first light emitting surface is connected to the first total reflecting surface. The second lens is defined in the second groove. The second lens is corresponding to the first lens. The third lens defined in the second groove. The third lens is corresponding to the second total reflecting surface.
