OPTICAL FIBER CONNECTOR AND OPTICAL COUPLING LENS

摘要

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.

主权项

1. An optical coupling lens comprising:
a main section comprising a first surface and a second surface opposite to the first surface, a first groove being recessed from the first surface to the second surface; the first groove comprising a third surface; a second groove being recessed from the second surface to the first surface, the second groove comprising a fourth surface; a beam splitting section comprising a first total reflecting surface and a second total reflecting surface opposite to the first total reflecting surface, a dihedral-angle between the first total reflecting surface and the second total reflecting surface being predetermined; at least one first lens defined in the third surface and comprising a beam splitter comprising a first light emitting surface connected to the first total reflecting surface; at least one second lens defined in the fourth surface and comprising a light incident surface, the at least one second lens corresponding to the first lens one to one; and at least one third lens defined in the fourth surface and comprising a third light emitting surface, the at least one third lens corresponding to the second total reflecting surface.
