MDE187-RH
- 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

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 (left handed version optional) | ||
| 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 (left handed version optional) | ||
| 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 | |||
