More on Nanopositioning Stages
PI is the global leader in piezoelectric nanopositioning and scanning systems. PI offers the greatest variety of standard systems as well as custom tailored solutions. PI Nanopositioning and scanning systems with frictionless flexure guidance are decidedly superior to positioners with conventional guiding systems in terms of resolution, reproducibility, straightness and flatness.
How to select the right nanopositioning stage?
Why Flexures? Flexure motion is based on the elastic deformation (flexing) of a solid material. Friction and stiction are entirely eliminated, and flexures exhibit high stiffness, load capacity and resistance to shock and vibration. Flexures are maintenance free and not subject to wear. They are vacuum compatible, operate over a wide temperature range and require neither lubricants nor compressed air for operation.
NanoAutomation: PI piezo stages are ideal for nano-automation applications, where nanometer precision in milliseconds is important.

Excellent Guiding Accuracy The multilink flexure guiding systems employed in most PI piezo nanopositioners (Fig. 2) eliminate cosine errors and provide bidirectional flatness and straightness in the nanometer or microradian range. This high precision means that even the most demanding positioning tasks can be run bidirectionally for higher throughput.
Lifetime / PICMA® Piezo Actuators PI nanopositioning systems employ the award-winning PICMA® piezo actuators, the only actuators with cofired ceramic encapsulation. The PIMCA® piezo technology was specifically developed by PI's piezoceramic division to provide higher performance and lifetime in nanopositioning applications. Multilayer piezo actuators are similar to ceramic capacitors and are not affected by wear and tear. PI nanopositioning systems are designed to be driven at lower voltages than most other piezo systems (100 V vs. 150 V). The research literature, PI's own test data and 30+ years of experience all confirm that lower average electric fields, lead to longer lifetime.
