M-682 Compact Closed-Loop Translation Stage with High-Force Powerful Piezomotor Drive

M-682 translation stages are low-profile, high-accuracy positioning systems based on the M-674 RodDrive ultrasonic linear motor actuator.  The M-682 positioner combines the advantages of its high-performance, high-speed drive with a high-precision guiding system and the superior accuracy of a direct-metrology linear encoder providing 0.1 µm resolution.

Capacitive Nanometrology Position Sensors Overview

Capacitive Metrology Sensors Introduction
PI capacitive (capacitance) sensors are the metrology system of choice for the most demanding nanopositioning applications. They are absolute-measuring, high-dynamics devices. PI capacitive sensors / control electronics use a high-frequency AC excitation signal for enhanced bandwidth and drift-free measurement stability (subnanometer stability over several hours, see Fig. 6, on Link).

Piezo Motors & Actuators

Piezo motors and linear actuators offer unique properties over conventional drives such as DC or Stepper.  With the active element manufactured from ceramic, applications in vacuum and non magnetic environments are feasible. PI has many different technologies, including single element and stacked actuators, PILine® which is a motor based  on an ultrasonic drive principle and NEXACT® and NEXLINE® which use a stepping (walking) principle.
