Abstract
An apparatus comprises a table, a source emitting polarized laser light, a source emitting laser light, a plate changing the polarization direction of the laser light, a plate splitting the laser light into a laser light having polarization in an X direction and a laser light component having polarization in a Y direction, a plate orienting the polarization direction of the laser light to the X direction, a lens converging the laser light components, a lens arranged in parallel with the lens along the X direction and converges the laser light component, a control section controlling a device such that a converging point of the laser light component is located at a predetermined position with reference to a front face by detecting a reflected light, and a control section moving the table along a line while making the X direction substantially coincide with the line.
