QS-5 OPD Galvanometer Scanner

Perfect for Hand-Held Scanning

 

QS-5 OPD Galvanometer Scanner - Nutfield TechnologyNutfield Tech’s QS-5 OPD Galvanometer brings high performance in a compact space. Our moving magnet scanners have a mechanical design that incorporates our exclusive ceramic ball-bearing motors that are combined with our high output position detectors. Patented low inertia optical detectors achieve dynamic performance with faster, more accurate positioning. The QS-5 features a recommended aperture of 3mm or 5mm. Minimum rotor inertia provides increased bandwidth and speed for stable, reliable performance.

When integrated with Nutfield’s QD-4000 Servo Amplifier, the QS-5 OPD galvanometer scanners deliver accuracy and speed in the palm of your hand.

Contact Nutfield Technology for assistance with identifying a solution for your scanning application.
