MDE520 - Elliot Gold™ Series Polarisation Maintaining Fibre Launch System with High Precision Adjusters

Elliot Gold™ Series Polarisation Maintaining Fibre Launch System with High Precision Adjusters   


  • 5 arc seconds rotational resolution
  • Orthogonal alignment grooves
  • 2 mm travel per axis
  • Suitable for PM fibre (125/250 µm cladding/jacket)
  • Ultra-stable patented design XYZ flexure stage
  • 20 nm linear resolution with patented†† high resolution adjusters

Elliot Gold™ Series Polarisation Maintaining (PM) fibre launch system comprising: 3-axis high precision flexure stage with high precision fibre (US: fiber) rotator, objective lens mount with RMS thread, and large fixed bracket. Suitable for launching free space light beams into PM fibre due to its accurate 3D flexure-based positioning.
PM fibre requires that the roll axis be adjusted to ensure correct alignment of the laser polarisation 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.
