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.

 MDI-H Piezo / Piezo Controller

The MDI-H with Piezo Drive is a mirror mount which is controlled by a piezo system with our own electronics. Besides a manual adjustment by 0.15mm / 0.25mm per turn, the systems can be adjusted electronically within a µm-range. The piezoelectric actuators are built into the mirror holder. Each of them have the following specifications:

The operation voltage range is -10 V ... +150 V, leading to maximum stroke of >20 µm (typically 23 µm).

Many of our optomechanical components can be equipped with piezo drives. For detailed information please contact us.

Our extremely precise laser contral as standalone unit as x, xy and xyz version with the different travel ranges between 50 and 180 mm.

These are our translation elements on the basis of a pre-stressed linear roller way, combined with a translation stage with linear roller way, free from play. The accuracy and reproducibility is of highest precision.

Specifications:

• Min. incremental motion 0,1 µm
• Max. 64.000 steps per turn
• Max. speed: 16.000 steps per second
• Max. load: 200N
• Limit and reference switches

A special feature is that the stepper motor can be controlled directly over a PC as the control card is isntalled inside the stepper motor. We can also offer a complete control box.
