Galvanometer scanning mirrors (galvos) are used far and wide in the photonics industry when a laser system requires active, precise beam steering. They are especially widespread in laser materials processing, where they are used in marking, engraving, micromachining, and other forms of machining.
A webcast produced on Wednesday, Oct. 23 by Laser Focus World, with Scott Schmidt, Laser Processing & Micromachining Group Manager at Aerotech as presenter, is all about the use of precision galvos.
Scott's presentation, called "Improving High-Speed Galvo System Accuracy," focuses on high-accuracy scanners used to produce parts with micron-level feature size; while such systems naturally should have micron-level (or better) accuracy, typically scanner performance is not qualified to this level of precision. Scott will talk about how to reduce overall errors, investigating how to minimize each of them and coax every last bit of precision from your galvos.
While this presentation is aimed at materials processing, any optical designer aiming to incorporate a galvo or galvos into a laser system can benefit from this talk. To register for the webcast, go to:
