Physik Instrumente (PI, Auburn, MA) has introduced two vacuum-compatible versions of the N-470 PiezoMike screw-type actuators. Providing a positional resolution of 20 nanometers and travel ranges between ¼ inch and 1 inch, the actuators are available for ambient applications and in high vacuum (HV, 10-6 Torr) and ultra-high vacuum (UHV, 10-9 Torr) configurations. The 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 integration into conventional mirror mounts, optics holders, or positioning stages.
