Linear actuator with PIShift piezomotor

Linear screw-type actuator with PIShift piezo inertia drive for high-resolution and stable positioning. Open-loop operation.

PIShift piezomotors
Compact, cost-effective inertia drive (Stick-Slip). When at rest, the drive is self-locking and therefore requires no current and generates no heat. It holds the position with maximum force.

Alignment of mechanical and optical components
Stable alignment of optical paths. Long-term positioning stability: High stability in target position, reliable start-up even after longer downtimes. High holding force and resolution by combining piezo actuators with mechanicalthread translation. Optionally vacuum-compatible to 10-⁹ hPa.
