6-Axis Nanopositioning Stages, Multi-Axis Piezo Stages

XY Stages     XYZ Stages     Single Axis Stages     Tip/Tilt Stages

PI's 6-Axis precision nanopositioning systems come in classical flexure-guided / planar designs and in hexapod (stewart-platform) type construction. Planar Flexure designs provide travel ranges of typically up to 1000 Ám with extremely good in-plane accuracy (straightness / flatness), hexapod designs on the other hand can be scaled to much larger travel ranges. PI also provides non-magnetic multi-axis positioning systems.

PIMars 6-Axis Piezo Flexure Stage Nanopositioning System 200Ám/1mrad

  • XYZ, Theta Z, Theta Y, Theta Z
  • Travel Ranges: 200 Ám Linear / 1 mrad Rotation
  • Enhanced Responsiveness & Multi-Axis Precision: Parallel Kinematics / Metrology
  • Closed-Loop, Capacitive Direct Metrology for Higher Linearity and Stability
  • Frictionless, Backlash-Free Flexure Guiding System
  • Excellent Scan-Flatness

The 6-Axis PIMars piezo flexure stage is one of the most advanced nanopositioning systems in the world. Its parallel-kinematic design, where all piezo flexure drives act on the same moving platform, and sophisticated digital control algorithms (see E-712 digital piezo controller) make it possible to achieve highly precise coordinated motion in all degrees of freedom, with straightness & flatness in the low nanometer range.

Custom systems with larger travel ranges or faster response are available on request.
