A beam splitter is an optical device that splits beams (such as laser beams) into two (or more) beams. Beam splitters typically come in the form of a reflective device that can split beams into exactly 50/50, half of the beam being transmitted through the splitter and half being reflected. Fig.2 outlines the uses of beam splitters.http://www.jxzb-mechanical.com/peeling-machine/
