Motorized Miniature Screw-Actuator

Physik Instrumente (PI) has introduced two vacuum compatible versions of its compact N-470 Piezomike precision screw-type actuator family.

Several OEM and bench top controllers for up to four channels are available. Versions with USB interface include host software and Labview drivers. Providing a positional resolution of 20 nanometers and travel ranges between ¼ inch and 1 inch, the actuators are now available for ambient applications and also in high vacuum (HV, 10-6 Torr) and ultra-high vacuum (UHV, 10-9 Torr) configurations.

N-470 actuators replace manual micrometer screws, and can be computer-controlled to simplify the automated adjustment of optics, lasers, and micro-mechanical components. Both metric and English mounts are available for easy integration into conventional mirror mounts, optics holders or positioning stages.
