Abstract:
1. A lens element comprising: a first surface for facing toward optical emitting elements or optical receiving elements; a second surface for facing toward optical fibers; at least one first communicating lens portion on the first surface; at least one second communicating lens portion on the second surface; and a first deflecting surface for deflecting optical signals between the least one first communicating lens portion and the at least one second communicating lens portion; wherein the lens element is shaped as a substantially right-angled triangular prism, the first surface and the second surface are the right-angled surfaces of the lens element, and the first deflecting surface is the bevel surface of the lens element; wherein the lens element further comprises a first testing lens portion, a second testing lens portion, a second deflecting surface, and a third deflecting surface, the first testing lens portion is configured for converging a detecting light, the second deflecting surface and the third deflecting surface are configured for deflecting the converged detecting light for a predetermined angle to direct the converged detecting light to pass out of the coupling lens through the second testing lens portion; wherein the second deflecting surface and the third deflecting surface are respectively located in grooves defined in the first deflecting surface.
