3.5 Technical Features

3.5.1 PICMA® Piezo Actuators
P-73x stages are driven by PICMA® piezo actuators. PICMA® actuators have
all-ceramic insulation and are therefore far superior to conventional actuators in
respect to performance and lifetime. The monolithic piezoceramic block is protected
against humidity and failure due to increased leakage current by a ceramic insulation
layer. In this way, an especially high reliability is achieved even under extreme
ambient conditions. In contrast to motorized drives, there are no rotating parts or
friction. The piezo actuators are therefore backlash-, maintenance- and wear-free.

3.5.2 Flexure Guides

P-73x stages have flexure guides (flexures) for frictionless motion and high guiding
accuracies.
A flexure guide is an element which is free from static and sliding friction. It is based
on the elastic deformation (bending) of a solid (e.g. steel) and does not have any
rolling or sliding parts. Flexure elements have a high stiffness and load capacity.
Flexure guides are maintenance- and wear-free. They are 100% vacuum compatible,
function in a wide temperature range and do not require any lubricants.
