Piezo-Driven Nano-Translation Stages Feature Record Travel Range


Piezo-Driven Nano-Translation Stages Feature Record Travel Range

Nanopositioning specialist PI (Physik Instrumente) has introduced the long-travel, piezo-driven P-628 series of nanopositioning stages.

Record Travel Range for Closed-Loop Piezo Stages
These monolithic positioning and scanning systems set a new record in terms of travel range for closed-loop, flexure-guided, piezo stages. Despite the increased travel range of up to 950 µm, the units are extremely compact, while providing rapid settling with nanometer-scale resolution and guiding accuracy.

The long travel range is achieved by a combination of a novel, friction-free and extremely stiff flexure system and the award-winning, ceramic-encapsulated PICMA® multilayer piezo actuators.

P-628 stages are ideal positioning systems for applications such as nanometrology, (white light) interferometry, microscopy, spectroscopy, and precision alignment of optics.

High Speed, Digital Control
A variety of 32-bit digital controllers provide fast communications and can read calibration data from ID-chips integrated in the nanopositioning stages. This feature allows easy interchangeability of stages and controllers without time-consuming recalibration. The stage's stiff design allows highly stable position control and higher throughput in automation applications.

A wide variety of software tools and LabView drivers is included with the controllers.
