Millisecond response, high stability, superior straightness & flatness, stiffness, digital control.
(Nanowerk News) Physik Instrumente (PI), a global leader in nanopositioning and precision motion control, provides a large portfolio of piezo flexure stages engineered for ultra-precise positioning in demanding industrial and research environments.
|
|
Designed for nanometer-level accuracy and high dynamic performance, PI’s piezo flexure stages combine friction-free flexure guidance with high-force and high-resolution piezoelectric actuation. 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.

Engineered for Precision and Stability
|
|
Unlike conventional bearing systems, monolithic flexure guides eliminate backlash, stiction, and mechanical play. This enables:
|
- Sub-nanometer resolution
- High stiffness, for short response times
- Deterministic, highly repeatable motion
- Long lifetime without mechanical wear
- 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 optimized for compact integration into OEM systems and automated production platforms. Available in single-axis, multi-axis stacked, and parallel-kinematic configurations, the portfolio supports:
|
- Linear travel ranges from tens of microns to over one millimeter
- Fast steering mirror applications for image stabilization, satellite communication and laser processing
- Fast focusing for microscopy and surface metrology
- Multi-axis positioning (XY, XYZ, tip/tilt) for scanning, optics and photonics alignment
- Load capacities from 100’s of grams to 100’s of kg
- 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 fiber-optics workflows.
|
|
Their fast response and high stability make them particularly well suited for active alignment and high-speed scanning tasks where conventional motorized 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.
