Precision Piezo Stage PPS-20
The PPS-20 is a high-precision, long travel linear piezo stage. Miniature crossed roller bearings assure high stiffness and guiding accuracy for loads up to 20 N （horizontal orientation）. It utilizes our patent-pending multi-phase piezo motor resulting in high speed （> 2 mm/s） and high blocking force （> 2 N）. The PPS-20 is available in open loop or with an external encoder. Closed-loop resolution of 2 nm is achievable. Versions capable of operation in vacuum （10-9 mbar） and/or cryo （4 Kelvin） are available. The PPS-20 is compatible with the MMC-100 and MMC-110 controllers.
