More Information
Summary:A multi-beam laser device is used to make a micro-retarder plate, which comprises a plurality of the first retardation state areas and the second retardation state areas alternating with each other. The device comprises an infra-red laser, a beam splitter, and a driving means. The beam splitter is used to split the laser beam into a plurality of equal intensity parallel beams and bring the parallel beams into focus. The driving mechanism is used to drive the beam splitter in one direction, and the beam splitter will scan a plurality of parallel scan lines by the direction on a surface.
