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:
ConfigurationRight handed version (left handed version optional)
Adjuster TypeThree high precision adjusters (Model MDE216) utilising a patented†† lever system with rotary fine and coarse control.
Stage travel2 mm in X, Y and Z axes
Resolution20 nm
Load capacity4.5 kg
Arcuate Displacement    X axis 20 µm (at maximum range of travel). Y and Z axes 14 µm (at maximum range of travel).
Optical axisThe 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:
ConfigurationRight handed version (left handed version optional)
Adjuster TypeTwo high precision adjusters (Model MDE216) utilising a patented lever system with rotary fine and coarse control.
RangeθZ (yaw)Coarse adjustment± 5º
  Fine adjustment± 0.1º
 θY (pitch)Coarse adjustment± 3º
  Fine adjustment± 0.1º
ResolutionθZ (yaw)Coarse adjustment5.5 arc seconds
  Fine adjustment< 0.1 arc seconds
 θY (pitch)Coarse adjustment5.5 arc seconds
  Fine adjustment< 0.1 arc seconds
Optical axisWhen 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-talkNo cross-talk - Rotation in a true arc
Visual IndicatorSwing-out pointer identifies the centre of rotation
MDE717 Rotation Stage:
Rotation adjustment360°
Coarse adjustmentEngraved scale ± 90°, vernier reads to 30 arc minutes
Fine adjustmentScrew with 5 arc seconds resolution
Range± 5°
Fibre fixturingFibre held in double V-groove by two clamp arms
Clamp loadAdjustable 25 to 125 g
V-block preset on axis with less than 1 µm concentricity error
V-block can be re-centred by user
