Linear actuator with piezo inertia drive

The internal piezo actuator slowly expands when an electric voltage is applied. This expansion leads to rotary motion of the claw. Because the claw clamps onto the fine-thread screw, the resulting motion then turns the screw. When the piezo actuator has reached its maximum expansion, it quickly contracts and the claw returns to its initial position. Due to rapid contraction, the claw slides around the screw. Due to its mass inertia, it remains in its initial position.

Alignment of mechanical and optomechanical components

Stable alignment of optical paths. Long-term positioning stability: High stability at target position, reliable startup even after longer downtimes. Versions to 10-6 hPa available.
