High-Speed Piezo Positioner Provides Improved Stiffness for Faster Response: PI Launches P-630 Direct-Drive Piezo Nanopositioning Stage
Date:7/19/2013

Auburn, MA (PRWEB) July 20, 2013

MARS Rover-proven piezo drive technology is behind PI’s new high-speed nanopositioning system. The P-630 linear stage achieves its high performance through a direct-drive mechanism and multi-layer piezo ceramic actuators. Its high mechanical resonant frequency of 3.25 kHz enables very rapid scanning speeds and step and settling times of only a few milliseconds.

The compact closed-loop piezo positioner provides 80 microns of motion with sub-nanometer resolution. With a height of 0.7” and width of 2 inches, the device integrates a large aperture of 1.2” an advantage for optical applications.

Technical data and specifications are available here: http://www.physikinstrumente.com/en/products/prdetail.php?sortnr=202550&onl_prw

The drive technology of the highly dynamic piezo nanopositioning systems is based on all-ceramic insulated PICMA® piezo actuators. They were tested by NASA for 100 billion cycles without failure.

Extremely high accuracy and stability in the nanometer and sub-nanometer realm is achieved by an integrated capacitance sensor and closed-loop operation with a digital servo piezo controller.

For high performance control, PI’s new E-709.CHG piezo motion controller is available. Its digital control algorithms provide better linearity than conventional piezo controllers and all motion parameters can be adjusted on the fly.
