MDE187 - Six-Axis Positioner fitted with High Precision Manual Adjusters

Precise Linear & Roll Fibre Adjustment in all Axes   

MDE187   

  • Based on ultra-stable patented design XYZ flexure stage
  • 2 mm linear travel in XYZ axes with 20 nm resolution
  • Roll adjustable through full 360° rotation
  • Roll resolution 5 arc seconds
  • Optical axis height 125 mm
  • Slotted design for easy insertion and removal of fibre
  • V-block preset on axis with less than 1 µm concentricity error
  • V-block can be re-centred by user
  • Pitch and yaw resolution < 0.1 arc secs
  • Pitch and yaw adjustments about a single point in space in a true arc with no cross-talk

The model MDE187, six-axis positioner is built up from the Elliot Gold™ Series of micro-positioning precision components.

It facilitates precise 6D manual adjustment of a fibre's position in XYZ linear axes, plus pitch (θY), yaw (θZ) and roll (θX) with excellent accuracy and long term stability.

The Six-Axis positioner comprises:

  • MDE185 Pitch and Yaw Stage (High Precision Adjusters)
  • MDE717 High Precision Fibre Rotator
  • MDE154 Clamp Set
  • MDE122 Elliot Gold™ Series XYZ Flexure Stage (High Precision Adjusters)


 

MDE187 Specifications

MDE122 XYZ flexure stage:
Configuration Right handed version
Adjuster Type Three high precision adjusters (Model MDE216) utilising a patented†† lever system with rotary fine and coarse control.
Stage travel 2 mm in X, Y and Z axes
Resolution 20 nm
Load capacity 4.5 kg
Arcuate Displacement     X axis 20 µm (at maximum range of travel). Y and Z axes 14 µm (at maximum range of travel).
Optical axis The optical height of all Flexure Stage accessories is 18 mm above the top plate. Therefore, the optical axis height of a mounted accessory is 94 mm above the bottom of the stage.
MDE185 Pitch and Yaw stage:
Configuration Right handed version
Adjuster Type Two high precision adjusters (Model MDE216) utilising a patented lever system with rotary fine and coarse control.
Range θZ (yaw) Coarse adjustment ± 5º
    Fine adjustment ± 0.1º
  θY (pitch) Coarse adjustment ± 3º
    Fine adjustment ± 0.1º
Resolution θZ (yaw) Coarse adjustment 5.5 arc seconds
    Fine adjustment < 0.1 arc seconds
  θY (pitch) Coarse adjustment 5.5 arc seconds
    Fine adjustment < 0.1 arc seconds
Optical axis When MDE185 is mounted onto an Elliot Gold™ Series XYZ flexure stage, the optical axis height is 125 mm above the bottom of the stage.
Cross-talk No cross-talk - Rotation in a true arc
Visual Indicator Swing-out pointer identifies the centre of rotation
MDE717 Rotation Stage:
Rotation adjustment 360°
Coarse adjustment Engraved scale ± 90°, vernier reads to 30 arc minutes
Fine adjustment Screw with 5 arc seconds resolution
Range ± 5°
Fibre fixturing Fibre held in double V-groove by two clamp arms
Clamp load Adjustable 25 to 125 g
V-block preset on axis with less than 1 µm concentricity error
V-block can be re-centred by user
Standard V-groove for 125/250 µm fitted
Split spring sleeve retains fibre in slot at the control end and prevents fouling during rotation
