Start-Of-Scan (SOS) laser for Polygon Scan Heads

It is common practice in low power polygon scanner systems to use the working beam to trigger a Start-Of-Scan (SOS) detector.  The SOS trigger is essential for accurate laser scanning. Polygon Scan Heads, used for material processing, employ high power…

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…
