Physik Intrumente (PI) has added two vacuum compatible versions to its compact N-470 PiezoMike linear actuator product line. The N-470.V (HV) and N-470.U (UHV) actuators are based on a cost-effective inertia drive (Stick-Slip). When at rest, the drive is self-locking and therefore requires no electric power and also generates no heat. It holds the position with a maximum force of 100 N.
For stable alignment of optical paths it is critical to provide excellent long-term positioning stability. The PiezoMike design provides this stability for long periods with reliable start-up even after longer downtimes. High holding force and resolution are achieved by combining piezo actuators with a mechanical rotation / thread translation. Vacuum-compatible to 10-9 hPa.
