Four-Axis Optical Mount

4LL-OM Four-Axis Optical Mount is a precise and robust solution for mounting telescopes, beam expanders, beam shapers, or any other heavy optics.

It allows optics adjustment in 4 degrees of freedom:

  • Two axes of angular adjustment can be tilted in a range up to ±4 degrees which are realized by two screws of thread pitch 250 μm (100TPI).
  • Two axes of lateral adjustment can be moved within ±2 mm and are driven by two screws of thread pitch 200 μm. Both – translation and rotation positions can be locked which secures long-term stability for heavy optics which is 4LL-OM core advantage over spring-based positioners.



  • Two-axis kinematic mount with two screws (thread pitch 250 μm (100TPI)) with position lock. Adjustment range up to ±4 degrees
  • Two-axis translation stage with ±2 mm travel range driven by two screws (thread pitch 200 μm). Translation stage with position lock
  • 5 mounting holes (M4) for convenient mount positioning
