Nanopositioning Stages – Compact

Piezo Nanopositioning Stages with Flexures, Travel Range to 1800µm

PI has extended its PIHera®  nanopositioning stage family - compact flexure-guided piezo stage    systems - now offering record travel ranges to 1800 microns.

X, XY, Z and XYZ Stage Versions
PIHera® piezo stages come in X, XY, Z and XYZ versions featuring travel ranges from 50 microns to 1800 microns for X and XY motion und up to 400 microns for vertical motion in Z.

Nanometer Precision for QA & Metrology Applications
These high precision closed-loop flexure-guided piezo stages can be used for scanning probe applications (surface metrology) and static positioning. Most PIHera® stages provide sub-nanometer resolution and even the 1.8 mm versions better than 3 nanometers resolution. The compact size is achieved with a new, friction-free and extremely stiff flexure system, which also provides fast response and excellent guiding accuracy; trajectory precision is in the low-nanometer range. High acceleration forces are provided by patented, long-life multilayer piezoelectric linear actuators. The ability to control motion with millisecond responsiveness and nanometer precision over long travel ranges makes PIHera® stages ideal for measuring and QA applications.

Capacitive Feedback Positon Sensors Offer Greater Motion Linearity
The piezo stages are equipped with non-contact capacitive- nano-measuring sensors and provide motion linearity to 0.02% with effective resolution in the sub-nanometer range. PI Capacitive Feedback are absolute-measuring, direct-metrology devices that boast very high bandwidth and exhibit no periodic errors. They are significantly less sensitive to influences by external noise and provide much better long term stability than strain gauge sensors.

Typical Applications
