Rotation Stages for Industry and Research
The PI group has extensive knowledge in the design and manufacture of highly precise rotation stages and positioning systems. Customers use our rotary stages in a variety of applications such as beamline instrumentation, fiber-optical alignment, semiconductor inspection, bio-medical instrumentation and X-ray crystallography.

The advantage of working with PI is the access to a large variety of different drive and guiding technologies.

Highest performance is guaranteed through the complete control of the design and machining process, the selection of components and assembly. Our air-bearing rotary stage selection is the most accurate in the industry with minimized eccentricity and wobble while providing the highest repeatability and accuracy. A variety of motors and drive principles are avaiilable from stepper-motor driven worm gear designs to direct drive closed-loop torque motors. Low profile piezo motor stages provide self-locking capabilities with zero jitter, drift and no holding current at rest.

Vacuum, too
As a specialist for vacuum motion systems, PI miCos also offers HV and UHV vacuum compatible linear positioning stages.

Piezo Motor Rotation Stages



PI offers ceramic-motor driven rotation stages with these two types:
  • Ultrasonic Piezo Motor Direct-Drive
  • Inertial Piezo Motor Direct Drive

Ultrasonic motors provide a very wide dynamic range, with very smooth motion, high speed and very fast start-stop behavior. Inertial motor drives are even more compact and cost efficient. Both systems are self-clamping and provide high stability, even when powered off.
