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.
