The PR-50 is a compact rotation stage with unlimited travel and a 1 inch aperture. Two pre-loaded steel ball bearings ensure smooth motion and high stability. It utilizes our patented multi-phase piezo motor resulting in high speed (> 25 º/s) and high
blocking force. 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-103 and MMC-110 controllers.
