Six-axis digital piezo controller with Super Invar nanopositioning stage
PI offers the largest selection of digital and analog motion con­trollers and power amplifiers for piezo actuators worldwide. The electronics play a key role for max­imum performance of piezoelectric nanopositioning systems, tip/tilt mirrors and actuators.
dynamic linearization and reduced settling times. For dynamic high­power applications, our energy-recovery power amplifiers provide up to 2000 W of peak power with minimal energy consumption, ideal for high-frequency actuation tasks.
Ultra-low-noise, high-stability
servo-controllers and amplifiers are essential, because piezo actua­tors respond to even microvolt changes of the control voltage with motion.
For industrial applications, where maximum throughput is crucial, PI offers digital control algorithms for
