OPTICAL APPARATUS FOR DUAL-BEAM LASER TEXTURING

A DISK TEXTURING TOOL IS USED, FOR EXAMPLE, TO PROVIDE TEXTURED SPOTS IN AN ANNULAR PORTION OF BOTH SIDES OF A HARDFILE DISK. DISKS ARE MOVED INTO AND OUT OF THE TEXTURING PROCESS IN CASSETTES, THROUGH TWO DISK-HANDLING STATIONS. AN OPTICAL SYSTEM INCLUDES A LASER DIRECTED AT A BEAMSPLITTER TO SPLIT...

Zusammenfassung:	A DISK TEXTURING TOOL IS USED, FOR EXAMPLE, TO PROVIDE TEXTURED SPOTS IN AN ANNULAR PORTION OF BOTH SIDES OF A HARDFILE DISK. DISKS ARE MOVED INTO AND OUT OF THE TEXTURING PROCESS IN CASSETTES, THROUGH TWO DISK-HANDLING STATIONS. AN OPTICAL SYSTEM INCLUDES A LASER DIRECTED AT A BEAMSPLITTER TO SPLIT THE LASER BEAM INTO TWO BEAMS HAVING APPROXIMATELY POWER, WHICH ARE DIRECTRED ALONG PARALLEL PATHS THROUGH A POWER CONTROL OPTICS BLOCK TO EXPOSE SIMULTANEOUSLY OPPOSITE SIDES OF A DISK TO BE TEXTURED. THE POWER CONTROL OPTICS BLOCK INCLUDES MEANS FOR ATTENUATING (136) AND MEASURING (136j) EACH OF THE TWO BEAMS. A SHUTTLING MIRROR DIRECTS THESE TWO BEAMS ALTERNATELY AT A DISK WITHIN EACH OF THE TWO DISK HANDLING STATIONS.FIG.5
