Motorized Miniature Screw-Actuator Provides 20 nm Resolution, Based on Piezo Effect
(Nanowerk News) Precision Motion specialist Physik Instrumente (PI) has introduced two new, vacuum compatible versions of its compact N-470 PiezoMike precision screw-type actuator family.
– Optics & Lasers
– Medical Engineering
– Physical Sciences
– Aerospace Engineering
– Photonics / Fiber Alignment
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.
Several OEM and bench top controllers for up to 4 channels are available. Versions with USB interface include host software and LabVIEW drivers.
