4, 5 & 6-Axis Nanopositioning Stages - Multi-Axis Motion

XY Stages     XYZ Stages     Single Axis Stages     Tip/Tilt Stages

PI's 6-axis stages and multi-axis and 6-DOF nanopositioning stages come in flexure-guided / planar designs, in hexapod (stewart-platform) type construction and as a combination of linear and rotary stages, for example with air bearing guides for long travel ranges w/o friction, wear and particle generation. For short travel, piezo nanopositioning stages (typically 100's of microns to a few mm), with parallel-kinematics flexure designs provide extremely good in-plane accuracy (straightness / flatness), air bearing stages and 6-DOF hexapod stages on the other hand can be scaled to much larger travel ranges. PI also provides non-magnetic multi-axis positioning systems.

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.
