Claim Text:
1. A beam-splitting integrated optical element, comprising: a shell, comprising a first lens surface, a second lens surface, at least one first reflective surface and at least one second reflective surface, the second lens surface being perpendicular to the first lens surface, the at least one first reflective surface and the at least one second reflective surface being located above the first lens surface, wherein a bottom edge of each of the at least one first reflective surface close to the first lens surface and a bottom edge of each of the at least one second reflective surface close to the first lens surface are not connected to each other; at least one first lens, disposed on the first lens surface, each of the at least one first lens having a first optical axis; and at least one second lens, disposed on the second lens surface, each of the at least one second lens having a second optical axis, wherein the at least one first reflective surface is located above the at least one first lens and inclined to the first optical axis and the second optical axis, each of the at least one first reflective surface is adapted to reflect at least a portion of a first beam from the corresponding first lens so that the portion of the first beam is transmitted along a first direction parallel to the second optical axis, each of the at least one second reflective surface is located at at least one side of the corresponding second optical axis and located on a transmission path of another portion of the first beam, and inclining directions of the at least one first reflective surface and the at least one second reflective surface are opposite so that the another portion of the first beam transmitted to the at least one second reflective surface is transmitted along a second direction different from the first direction after being reflected by the at least one second reflective surface.
