Miniature Screw-Actuators provide 20 nm resolution.

Press Release Summary:




Providing travel ranges from ¼–1 in., N-470 PiezoMike Actuators are available for ambient applications, and in high vacuum (10-6 Torr) and ultra-high vacuum (10-9 Torr) configurations. Units can be computer-controlled to facilitate automated adjustment of optics, lasers, and micro-mechanical components. When at rest, drives are self-locking, require no electric power, and generate no heat. Holding force of >22 lb and self-clamping design make actuators vibration-proof and shock-resistant.

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 simplifiy 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.



Self-Locking, No Heat Generation at Rest

When at rest, the drive is self-locking, requires no electric power and generates no heat. The high holding force of >100N (22 lbs) and its self-clamping design make it vibration-proof and shock-resistant.



Controllers

Several OEM and bench top controllers for up to 4 channels are available. Versions with USB interface include host software and LabVIEW drivers.
