New PI Catalog: Nanopositioning Actuators Jun 16, 2008

Sub-µm to sub-nanometer precision compact actuators: novel ceramic motors to classical motors.

Systems range from high-force non-magnetic ceramic actuators for high-energy physics & astronomy (vacuum) applications to pen-tip-sized ceramic actuators for high-volume optics & medical applications.

High-speed ultrasonic actuators provide velocity to 800 mm/sec (32 in/sec) and accelerations to 20g, while flexure actuators respond to control input in as little as a few 100 µsec to operate fast pumps or position optics in high-speed focusing or alignment applications.
