The PZ3 series is the mid-range members of Optiphase’s family of fiber stretchers. At the core of the PZ3 mid-range fiber stretchers is a fiber wound piezoelectric element for use in a wide range of optical interferometric measurement and sensing system applications.

Optiphase’s expertise in the design, manufacture and use of all-fiber interferometers has produced a unique multi-layer winding approach resulting in an enhanced modulation function while maintaining a high operational frequency. PZ3 mid-range fiber stretchers are available with single mode (SM), commercial polarization maintaining (PM, Panda or Bowtie) or SM reduced cladding (RC) fiber types

PZ3 mid-range fiber stretchers are available in two versions:

• Housed in an enclosure with connectors, making set-up and use quick and easy
• Bare lead fiber stretcher, not enclosed and including a convenient mounting kit consisting of a top-mount aluminum retainer and two silicone rubber pads - the mounting kit includes top or bottom mount

Optiphase fiber stretchers are unique in that they do not require proprietary drivers. For most low-voltage applications (<±15 V) Optiphase stretchers can be driven by standard electronics such as signal generators, op-amps or other laboratory equipment without modification. For more information on how to drive PZ3 mid-range fiber stretchers see the downloadable application note.
