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 available 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.
