QS-12 OPD Galvanometer Scanner
For Exceptional Performance and Value
Delivering Speed and Reliable Accuracy
The QS-12 OPD Galvanometer Scanner offers strong performance and value for steering 10mm, 15mm, and 20mm aperture mirrors. Our groundbreaking optical position detector design enables an unsurpassed combination of high linearity and low drift required for high precision applications. When integrated with Nutfield’s QD-4000 Servo Amplifier, the QS-12 OPD moving-magnet galvo delivers exceptional speed and accuracy in compact, affordable configurations.
Nutfield Tech’s mechanical design uses low resistance/low induction coils for increased scanning speed and optimized thermal characteristics. Our OPD generates 4 times the output signal for high signal/noise ratio and outstanding accuracy.
