XYZ Flexure Stages

MDE122

Elliot Gold™ Series XYZ Flexure Stage with High Precision Manual Adjusters

The Elliot GoldTM Series XYZ flexure stage is a development of the immensely popular original stage invented and patented* by Martock Design, now a subsidiary of Elliot Scientific. Flexure stages are ideal for high precision device manipulation. Applications range from fibre launch systems for single-mode, multimode and polarization maintaining fibres as well as waveguide alignment, through to the manipulation of microstructures in bioscience. The arcuate displacement (vertical displacement due to longitudinal flexure motion) is up to 4 times better than competing products.

The optical axis height of all accessories is 18mm above the top plate, placing the optical axis 94mm above the bottom of the stage.

2 & 3 Axis Rotation Modules

MDE185

Pitch and Yaw Stage with High Precision Adjusters

The MDE183 and MDE185 Rotation Stages add pitch and yaw adjustments to the Elliot GoldTM Series XYZ flexure stages. Applicable to a wide range of fibre and device alignment tasks requiring the ultimate in flexibility and precision control.

The MDE185 pitch and yaw module provides a +/- 3º range in pitch and a +/- 5º range in yaw, with a resolution of < 0.1 arc secs. The module has a locating slot to accept Elliot/Martock standard top plate accessories such as fibre holders allowing bare fibre, ribbon cable and connectorised fibre to be used with the rotation module. A locating tongue on the base interfaces with the top plate of the flexure stages. When fitted with a fibre rotator and attached to a stage, the module allows 6-axis manipulation of a fibre about a single point in space. A swing-out pointer identifies the rotation centre for ease of use.

The MDE183 and MDE185 can be used with various top plate accessories from the Elliot/Martock range. These stages can also be mounted on riser blocks for 94mm or 125mm optical axis height. The MDE190 riser block is used to extend the axis height of an MDE147 or MDE148 bracket to 125mm for 5 or 6 axis fibre launch applications.

All accessories are compatible with the flexure stages. The optical axis height is 18mm 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 all accessories requiring attachment in this format are supplied with a clamp set.

MDE884LH

Fibre Array / Crystal Rotator, Long Reach, Left Hand

θx ribbon cable / crystal manipulator (long reach). Unique roll mechanism ensures rotation is exactly about x-axis, and maintains 18mm centre height. Right and Left handed versions available. Can also be supplied with θy and θz adjustments. Front block is machined by Elliot Scientific or Customer to locate silicon V-groove block on the fibre ribbon.

The unique mechanical roll design features a decoupling of the linear adjuster travel from the roll motion, which minimizes any radial offset during rotation. This ensures that angular movements are exactly about the x-axis and that no radial offset is introduced. The precision of motion results in a very high level of accuracy of the roll angle.

Options and Accessories:
Right-hand and left-hand versions
θy and θz adjust options
Motorised adjusters
Fibre array clamps
Inverted drive version if space is limited
MDE884LH is compatible with MDE183 and MDE185
