LASER PROCESSING APPARATUS USING POLYGON MIRROR TO IMPROVE SAWING EFFICIENCY

摘要

PURPOSE: A laser processing apparatus using a polygon mirror is provided to improve cutting efficiency by eliminating the necessity of an additional replacement process of equipment and by performing a cutting process while using only laser. CONSTITUTION: A laser generation unit generates and outputs laser. A polygon mirror(10) includes a plurality of reflection surfaces(12), rotating with respect to an axis. The polygon mirror reflects the laser that is generated from the laser generation unit and is incident upon the reflection surface. A lens(20) collects the laser light reflected from the polygon mirror to irradiate the laser light to an object to be processed.
