M-035 DC Motor Driven Precision Rotation Stages

  • Closed Loop DC Motor with 1 µrad Resolution
  • Piezo Option for High Resolution, Dynamic Scanning and Tracking
  • 360 ° Coarse Range, 12 ° Fine Range
  • 20 mm ∅ Clear Aperture
  • Standard Limit Switches

M-035 series precision rotation stages feature high resolution, excellent repeatability and minimum wobble. The stages are equipped with double ball bearings for minimum backlash and high load capacity. Both the rotation platform and the scale ring (graduated in 2 degree increments) can be independently coarse positioned over 360 degrees and then be locked by screws.

The basic version, M-035.D0, is equipped with a DC servo motor drive providing a positioning range of ± 6.3 degrees. A set of limit switches eliminates the possibility of overtravel.

The versions M-035.DS and M-035.DP provide additional piezoelectric fine adjustment over a range of ±520 µrad. The piezoelectric fine adjustment also allows dynamic operation such as scanning or tracking. The .DS version is equipped with a closed loop PZT drive (model P-841.30), while the .DP version comes with an open loop PZT drive (model P-840.30). Both drives provide a linear range of 45 microns and sub-nanometer linear resolution (see "PZT Actuators" section for further details and recommended drivers).
