ABSTRACT:
A beam shaper including a reflection device and a plurality of reflectors. The reflection device is disposed on a transmission path of an incident light beam and has a plurality of reflection surfaces capable of reflecting the incident light beam. The reflection surfaces are capable of splitting the incident light beam into a plurality of reflected light beams. The reflectors are separately disposed on transmission paths of the reflected light beams. The reflectors are capable of reflecting the reflected light beams, so that a shaped light spot is formed by superimposing light spots of the reflected light beams. The reflection device is disposed between the shaped light spot and the reflectors.
