From the standpoint of the optics, there is one major limitation to this approach. This is that most
scan lenses are designed to cover a "flat…

…wavelengths in the visible and IR. But,
again, heat builds up and fast scanning or parallel processing is often beneficial.
Thus, systems that provide fast and high-accuracy
scanning using galvanometer mirror and stage combinations could be significant for micromachining, Sercel

bottle (FIGURE 1). The 355 nm laser, working with a focused spot size of 30µm, was
scanned over the part surface using a galvanometer mirror system. In this configuration, high-contrast, 8 × 8mm barcode patterns were generated in 2s.
The MATRIX 355 is…
