SCANNER OF POWERFUL LASER RADIATION Russian patent published in 1995 - IPC

FIELD: optics. SUBSTANCE: scanner is intended for scanning of laser beam with rectilinear trajectories on to treated surfaces. Scanner includes electric motor drive, mandrel put on shaft of electric motor drive. Reflecting element of ring shape made of restoring material is installed in mandrel. Reflecting element is so bent that its reflecting surfaces forms circumference on axis of shaft with radius r with crossing of one of cylindrical surfaces coaxial to shaft axis. For fixed radii different from radius r not less than one section of helical line is the crossing. Gap between reflecting element and mandrel is filled with heat conducting plastic material. Nonworking surface of mandrel is manufactured in the form of heat-sink to dissipate heat. Reflecting element is mounted in mandrel for adjustment and fixing of its bending. EFFECT: simplified design, enhanced efficiency of laser treatment. 5 cl, 8 dwg
