Things you need to know about specifying polygon mirrors for laser scanning

In the world of material processing, galvanometer (galvo) scanners dominate.  However, with high power and ultra-fast (picosecond & femtosecond) lasers, galvos may not be fast enough.  With a need for higher speed, people are looking at implementing polygon scanners which…

Laser damage threshold – Galvo Mirror vs Polygon mirror

Laser damage to galvanometer (galvo) mirrors is a major issue in some high power applications.  The galvo mirror(s) may be the weak link preventing use of higher power lasers which would allow processing material at a faster rate.  This is…

Galvanometer scanners not fast enough for your new laser or application?

Since the laser was invented, galvanometer (galvo) scanners have been used for scanning the beam. Galvos are ideal for high power / low speed material processing applications.  Every year laser power goes up.  Higher power allows faster processing which means…

Road Runner 70,000 RPM polygon scanner solves the noise problem

Polygon scanners are used for high speed laser scanning.  A multi-faceted polygon can be rotated at tens of thousands of RPM to produce scan rates far higher than galvanometer scanners.  Galvanometer aka Galvo scanners are limited primarily by the inertia…
