Positioning devices capable of nanometer or sub-nanometer resolution that are equipped with direct metrology position feedback provide excellent guiding accuracy over long travel ranges.

PI (Physik Instrumente) L.P. offers a broad portfolio of nanometer precision motion technologies including everything from piezo-driven nano-positioning stages to motorized 6-axis hexapod positioning systems. The advantages of PI piezo stage positioning systems include increased reliability in industrial applications, increased multi-axis trajectory control and digital controls that offer a wider dynamic range, better linearity and auto-calibration.

A wide range of applications including image scanners, overlays, autofocus, interferometry and super-resolution microscopy benefit from PI’s extensive portfolio of nanometer precision positioning devices. In addition, PI also provides an air bearing nano-positioning stage for longer travel ranges as well as unique hybrid designs.
