Elliot Gold™ series Polarisation Maintaining Fibre Launch System with Standard Adjusters   


  • Approximately 0.1 degrees rotational resolution
  • Suitable for PM fibre (125 µm)
  • Orthogonal alignment grooves
  • 200 nm resolution
  • 2 mm travel per axis
  • 4.5 kg load capacity
  • Ultra-stable patented design XYZ flexure stage

Elliot Gold™ Series polarisation maintaining (PM) fibre launch system comprising: 3-axis  manual flexure stage with standard fibre (US: fiber) rotator, objective lens mount with RMS thread, and small fixed bracket.
Suitable for launching free space light beams into PM fibre as this requires the roll axis to be adjusted to ensure correct alignment of the laser and fibre polarisation axes.

All accessories are compatible with the Elliot Gold™ series flexure stages. The optical axis height is 18 mm above the platform surface and on the centre line of the location slot. Where necessary a locating tongue forms part of the accessory. A standard clamp system is used and is supplied with the flexure stages and accessory platforms. The choice of objective lens is subject to user preference, and must be ordered separately. Extra clamp sets (MDE154) are available if required.
