Description
The OPTIPHASE PZ3 is the mid-range member of our family of fiber stretchers. It is a fiber wound piezoelectric element for use in a wide range of optical interferometric measurement and sensing system applications. Typical uses include open loop demodulation, sensor simulation, variable optical delay, general purpose fiber interferometry and large angle modulation of interferometric phase.
Optiphases 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 [see charts]. PZ3 Fiber Stretchers are available with SM, commercial PM [PANDA or Bowtie] or RC [SM Reduced Cladding] fiber types. Fiber stretchers with connectors are housed in an enclosure, making setup and use quick and easy. These fiber stretchers are unique in that they do not require proprietary drivers. For most low voltage applications (< 15V) our stretchers can be driven by standard electronics such as signal generators, op-amps or other laboratory equipment without modification.
