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…
It is a fine achievement for Road Runner to push the top speed of polygon scanning to a record breaking 70,000 RPM and to solve the noise problem with a whisper quiet design! See and hear a Road Runner demonstration…
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…
A company was paying a lot for top quality German made F-Theta lenses. Less expensive lenses did not have the optical quality to meet the high accuracy in their material processing application. They found that Geomatec F-theta lenses from Japan…
