Galvanometer Scanners

QS-5 OPD Galvanometer Scanner

Strong performance in hand-held scanning

The QS-5 OPD moving-magnet galvanometers bring high performance in a compact space. Our mechanical design 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. When integrated with Nutfield’s QD-4000 Servo Amplifier, the QS-5 OPD scanners deliver accuracy and speed in the palm of your hand.
