Hi Simon,
piezoelectric actuators cannot allow mm range movements directly (also
because of significant issue about power supply), amplified piezo
actuators can reach 1 or 2 mm range but aren't easy to handle as
microscopy stage (sse for example
http://www.directindustry.com/prod/dsm/amplified-piezoelectric-actuators-16752-91527.html). On the other hand, as already said, hybrid stages (that have piezo systems on position encoder) permit tens of mm travel range with hundreds of nm (typically 0.1 um) position accuracy and repeatibility. Lot of good commercially available products in this case. Write me if you want more details on our
choice.
Hope it helps
Francesca
