Spatial beam shaping is very important in various laser microprocessing techniques like scribing, PCB drilling and others where scanning over working field with using galvo mirror scanners is used. Therefore, combining of beam shaping optics, converting Gaussian to flattop (uniform) laser beam irradiance profile, with scanning optical heads is an insistent technical task. As a p...$28.00
