Outstanding lifetime due to PICMA® piezo actuators
The PICMA® piezo actuators are all-ceramic insulated. This protects them against humidity and failure resulting from an increase in leakage current. PICMA® actuators offer an up to ten times longer lifetime than conventional polymer-insulated actuators. 100 billion cycles without a single failure are proven.
Subnanometer resolution with capacitive sensors
Capacitive sensors measure with subnanometer resolution without contacting. They guarantee excellent linearity of motion, long-term stability, and a bandwidth in the kHz range.
High guiding accuracy due to zero-play flexure guides
Flexure guides are free of maintenance, friction, and wear, and do not require lubrication. Their stiffness allows high load capacity and they are insensitive to shock and vibration. They work in a wide temperature range.

Technology
PICMA® Technology
Highly reliable and extended lifetime through the patented manufacturing process for multilayer actuators.
Flexure Guiding Systems
Flexure guides from PI have proven their worth in nanopositioning. They guide the piezo actuator and ensure a straight motion without tilting or lateral offset.
Digital Motion Controllers
Digital technology opens up possibilities for improving performance in control engineering which do not exist with conventional analog technology.
Capacitive Sensors
Capacitive sensors are the metrology system of choice for the most demanding nanopositioning applications.
Applications
Genome Sequencing
Be it in medicine, forensics, or genetics - the genome is the key to new insights for numerous questions. The method known as sequencing-by-synthesis, which used to decipher the genome, has become faster and more precise since it was first developed — the cost has decreased, respectively. The positioning techniques employed in the microscope systems used for this purpose have also contributed to...
IsoView Light Sheet Microscope
Light Sheet Microscopy is a fascinating technology with a huge application potential in life sciences and biotechnology. IsoView is a brilliant interpretation of this technology, especially intended for imaging fast cellular dynamics across large specimens over several hours. Specimen positioning and objective translation plays a major role in the design of IsoView.
GATTAscope (TIRFM)
Linear stages adjust the laser beam in the TIRF microscope. Precision positioning of the sample is possible by combining two XY stages.
High-Speed Microscopy
For the first time ever, scientists from the Fraunhofer Institute for Production Technology IPT in Aachen have succeeded in achieving 100 percent microscopic testing in the industrial environment. The piezo-based PIFOC® drive system from PI was decisive for this success.
