Multibeam laser device for fabricating a microretarder by heating process |
摘要 |
A multi-beam laser device is used to make a microretarder plate, which comprises a plurality of first retardation state areas and second retardation state areas alternating with each other. The device comprises an infrared 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.
