The PR-50 is a compact piezo rotation stage with unlimited travel and a 1 inch aperture. Two pre-loaded ball bearings ensure smooth motion and high stability. It utilizes our patent-pending multi-phase piezo motor resulting in high speed (> 25 °/s) and high blocking torque. The PR-50 can be combined with the linear PPX-50, PPS-60, or VT-50 stages without an adapter bracket. Versions capable of operation in vacuum (10-9 mbar) are available. The PR-50 is compatible with the MMC-100 and MMC-110 controllers. PR-50壓電旋轉台
