Guided Piezo Nanopositioning Stage with Frictionless Z Motion

Description

PIHera Z flexure-guided piezo nanopositioning stages provide vibrationless motion with virtually unlimited resolution and fast response and have record travel ranges of 50 µm to 250 µm (400 µm open-loop).

There are no rolling elements, so there is no bearing rumble, so the motion is smooth and straight.

They are equipped with absolute-measuring direct-metrology capacitance sensors and provide resolution down to 0.1nm, in a compact, FEA optimized package for high stiffness and long lifetime. Direct metrology provides higher stability and linearity compared to inferred metrology feedback – usually based on piezo resistive strain gauges, a technique also available from PI for entry level piezo nanopositioners.
