- Nanometer resolution and micrometer displacement
- Load capacity up to 4000 N per actuator
- Temperature sensor
- Long-term stability without a permanent power supply
- Easy readjustment of machines at inaccessible locations
- Avoids time-consuming manual adjusting processes
Fields of Application
- Precision mechanics
- Static precision positioning
- Metrology/interferometry
- Set-and-forget applications
- Adaptive mechanics
- Drift compensation
- Alignment of optical components
High User-Friendliness Due to Automatic Configuration
When the electronics are turned on, the mechanic’s ID chip, which contains crucial operating characteristics, is automatically read out.
Long-Term Stable Positioning Without Permanent Power Supply
Actuators equipped with PIRest technology keep their position steadily after being moved without a constant control voltage supply. Modifications are affordable, easy to maintain, and with nanometer precision even at remote sites.
