LENS ELEMENT AND OPTICAL COMMUNICATION APPARATUS WITH SAME

摘要

A lens element includes a first surface, a second surface, 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 at least one first communicating lens portion and the at least one second communicating lens portion. The lens element further includes a first testing lens portion, a second testing lens portion, a second deflecting surface, and a third deflecting surface. The second deflecting surface and the third deflecting surface deflect a detecting light converged by the first testing lens portion at a predetermined angle so that the detecting light passes out of the lens element through the second testing lens portion.
