LASER CUTTER AND SLITTER WITH SAME

摘要

This laser cutter (10) is a device for cutting a polarizing film (6) by applying a laser beam (L6) thereto. The laser cutter (10) is provided with: a laser beam oscillator (1) for oscillating a laser beam (L1); a bend mirror (3) for reflecting the laser beam, which is oscillated by the laser beam oscillator (1), to the polarizing film (6); and a condenser lens (5) disposed between the polarizing film (6) and the bend mirror (3) and condensing a laser beam (L6). A beam splitter (4) through which the laser beam (L3) is transmitted and by which the laser beam (L3) is reflected is provided between the bend mirror (3) and the condenser lens (5).
