Where this stage fits

This stage provides fine, limited-angle orientation rather than continuous rotation. Its ±1° range is intended for trimming the angle of mirrors, detectors, samples and other components around a fixed mechanical axis.

Why Piezo LEGS® direct drive

Direct actuation removes a geared rotary transmission from the motion path. This avoids gear backlash and supports repeatable small-angle corrections. The integrated optical scale provides 0.4 arcsecond closed-loop resolution, and the stage can maintain its selected angular position without continuous motor power.

Small movement. Big impact.

When precision defines performance, every movement matters. Piezo LEGS® technology delivers direct, controlled motion without the complexity of conventional transmission mechanisms.

Typical applications

  • Mirror and optical-element alignment
  • Detector orientation
  • Precision angular inspection
  • Laser beam steering
  • Calibration and metrology

What this enables

  • Trim the angle of a mirror or optical component during automated alignment.
  • Orient a detector or sample by fractions of an arcsecond for measurement.
  • Apply repeatable limited-angle correction without a geared rotary transmission.

Find your fit.

Use this stage when the task is precision angular correction within ±1°, not continuous indexing or full rotation. Check payload mass, inertia, centre of gravity, applied moments and required angular speed against the complete application.
