Frictionless motion for nanopositioning, scanning and alignment applications

Closed-loop position control is enabled by a selection of high-resolution, absolute measuring sensors, depending on the target application. The result is exceptional repeatability, fast settling times, and virtually wear-free operation - ideal for applications requiring stable, high-bandwidth motion over small travel ranges.

Unlike conventional bearing systems, monolithic flexure guides eliminate backlash, stiction, and mechanical play. This enables: sub-nanometre resolution; high stiffness, for short response times; deterministic, highly repeatable motion; long lifetime without mechanical wear; and high load capacity relative to size.

Space-tested reliability

PI piezo flexure stages incorporate the company's patented PICMA multilayer actuators that were selected for the Mars Mission by NASA, after completing 100,000,000,000 (100 billion) test cycles without failure.

Compact design, high performance

PI's piezo flexure stages are optimised for compact integration into OEM systems and automated production platforms. They are available in single-axis, multi-axis stacked, and parallel-kinematic configurations.

Vacuum and cleanroom applications

When paired with PI's high-performance digital motion controllers, including advanced scanning and alignment firmware, the stages enable high-throughput test and production in automated optics and fibre-optics workflows. Their fast response and high stability make them particularly well suited for active alignment and high-speed scanning tasks where conventional motorised stages cannot meet bandwidth requirements.

A scalable technology platform

With decades of experience in piezoelectric motion control, PI provides not only the mechanical platform but a complete motion ecosystem - including controllers, software, alignment algorithms, and system integration support. This scalable approach enables customers to move efficiently from laboratory setups to automated production environments.
