QS-30 Moving Magnet Galvanometer
The Workhorse of Galvos
The QuantumScan-30 is a flexure-based galvo ideal for laser cutting & welding applications.
Nutfield Technology’s QS-30 Moving Magnet Galvanometer offers strong performance and value for steering 30mm and 45mm aperture galvo mirrors. It is the first galvanometer to use a ceramic rotor to reduce rotor inertia and increase rotor stiffness. (Increased rotor stiffness raises the galvanometer’s resonant frequency, which allows improved step response.)
The QS-30 Moving Magnet Galvanometer is designed to rotate optical scanning mirrors at a high bandwidth and settle to a high degree of accuracy and repeatability. It can handle inertias in the 0.6 to 80 g-cm2 range. The exact inertia that can be driven depends on the application requirements.
When integrated with Nutfield’s QD-4000 servo amplifier, the QS-30 galvanometer scanners deliver accuracy and speed in compact, affordable configurations.
