QS-30 Galvanometer

QS-30 moving magnet galvos offer strong performance and value for steering 30mm and 45mm aperture galvo mirrors. Our ceramic rotor provides increased stiffness and reduced inertia for fast scanning. When integrated with our QD-4000 servo-amplifier, QS-30 galvo-based single- and multi-axis scanning sub-assemblies provide speed and accuracy in compact, affordable configurations.

QS-30 galvos are primarily offered as components of scanning subsystems, such as:

  • Single-axis scan sets – include galvo with mounted mirror, servo-amplifier, and cable set. These are used for single-axis beam steering.
  • Open-frame 2-axis scan heads – These are used for steering beams in X/Y, often where there is no desire to focus the beam to a small spot.
  • 3-axis scan heads – These are used for beam steering in X/Y or X/Y/Z for applications where a scanned beam is focused to a small spot at the work.
  • Fiber laser scan kits – when matched with certain fiber lasers, Nutfield Fiber Laser Scan Kits provide items necessary to integrate a laser-scanning engine. The kit streamlines the integration process, and provides support & service benefits of a single point of contact for the scanning sub-assembly.

See the Nutfield’s Product Selection Calculator or contact Nutfield for assistance with identifying a solution for your scanning application.
