PZT linear stage

BACK

Diffraction International´s PZT Linear Stage uses a wire-EDM flexure design to achieve linear translation without tilt or tip. Use it to add Durango phase measuring capability to your Twyman-Green or small Fizeau interferometer, or use it to move a test optic or return flat external to your Fizeau interferometer. An internal preload insures high stiffness. If the load is not cantilevered excessively, a 2 kg mass can be driven with good linearity and stability.

The PZT Linear Stage measures 65 mm x 45 mm x 12.7 mm. It has counter bored mounting holes at each corner for attachment to metric M6 or English 1/4-20 optical breadboards. Attach a load to the raised top surface by means of the 5 tapped M4 holes and 2 counterbored M4 holes. The low voltage, open loop PZT element has a nominal scale factor of 150 nm per volt and can be driven directly (without voltage amplifier) by any National Instruments DAQ card. An RG-93 LEMO-to-LEMO or LEMO-to-BNC cable is included.
