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…
Polygon scanners have been used in laser printers, copy machines and other lithographic applications for more than 40 years. It is well proven that polygon scanners are capable of high speed scanning with “photographic quality” accuracy. I like the term…
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…
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…
Graphene is a single-layer of carbon atoms with extraordinary quantum electronic properties. It is a transparent, flexible material which is 200 times stronger than steel. It conducts electricity better than copper and has the highest thermal conductivity known to man.…
ULTRAFAST / USP (picosecond and femtosecond pulse) lasers are a game changer. Slower lasers have a heating effect. Molten material tends to splatter and a Heat Affected Zone may alter the surrounding material in an undesirable way. ULTRAFAST lasers have…
