Lincoln Laser Co.’s KW Series polygonal laser scanners feature
copper mirrors for materials processing applications using high-energy laser sources.
When galvanometer mirrors are enlarged to compensate for high-power lasers, the
scan rate slows down. The polygonal scanners dissipate heat more efficiently and
produce faster scan rates because the copper substrate acts as a large heat sink
that draws heat away from the mirror facets. Additional heat dissipation occurs
as the polygonal mirror rotates, allowing the laser beam to transfer rapidly from
facet to facet and minimizing dwell time on any single facet. The scanners accommodate
beam power densities of 1000 W/mm2 and produce scan angles of >120° and
scan rates of >10 kHz. They can be custom designed to meet thermal, optical,
speed and accuracy requirements for lasers of all wavelengths and power levels.
