Item # N-470, N-470 PiezoMike Linear Actuators

Minimum dimensions, high forces, stable positioning

Compact design

Self-locking, no heat generation at rest

Linear actuator with piezo motors
Linear screw-type actuator with piezo inertia drive for high-resolution and stable positioning.

Alignment of mechanical and optomechanical components
Stable adjustment in optical paths. Long-term positioning: High stability at target position, reliable startup even after longer downtimes. High holding force and resolution by combining piezo actuators with mechanical thread translation.

Piezo motors
Compact, inexpensive inertia drive principle (stick-slip). The drive is self-locking at rest, requires no current, and does not generate any heat. It holds the position with maximum force.
