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.

Abstract: A microfluidic chip including a substrate and at least a channel set is provided. The substrate has a surface, and the channel set is formed in the substrate and includes a channel, at a least a filler fillister, and at least a well fillister. The filler fillister and the well fillister are all connected to the channel, and the channel passes through the well fillister. The depth of the well fillister relative to the surface is longer than the depth of the channel relative to the surface. Hence, the well fillister can hinder the fluid flow in the channel and be used as a valve.
