PZ1 Fiber Stretchers

Gas Leak Rate <1 x 10-8 scc/s; Fiber Type SM, MM, PM, High-Power Fibers; Cladding Diameter 125 to 1000 µm; Sealant Teflon, Viton; Operating Temperature -180 to +230 °C OZ Optics’ VAC series of fiber optic vacuum pressure feedthroughs provide a simple way to use optical fibers with vacuum and pressure chambers. They are available in two versions - a penetrating feedthrough fiber version and a receptacle style version. Penetrating versions have the fibers directly installed. One or four fiber versions are available. The fibers are installed in the OZ Optics factory. The fibers pass through a soft sealant material which is compressed by the compressive endcap and internal squeezer of the feedthrough. This conforms the sealant material surrounding the fiber, sealing the hole. A variety of sealant materials can be used. Viton is recommended for most applications up to +230 °C, and Teflon for cryogenic applications. A 1/4” NPT thread vacuum feedthrough is our standard. 1/8” NPT thread is also available for single channel assemblies with no connectors. In penetrating versions, the fiber can be protected in 900 µm loose tubing or a 3 mm OD stainless steel cable. The receptacle style version contains a short fiber stub, which is sealed using a vacuum rated glue. An O-ring is used between the chamber wall and the flange to seal the system. Adapters for various standard connectors are available. Key Features: Vacuum or Pressure Seal; Fiber in Penetrating Style Can Be Protected in Loose Tubing or Stainless Steel Cable Rugged Design Compact Low Transmission Loss (Excluding Connector Losses) Easy Installation Wide Range of Connector Types Single Fiber and Four Fiber Penetrating Versions Available Receptacle or Penetrating Type Available Operating Temperature Receptacle Type: -35 to +90 °C Operating Temperature Penetrating Type: -20 to 230 °C (Viton), -180 to +230 °C (Teflon) Applications: Laser Power Delivery or Optical Sensing in a Pressure or Vacuum Chamber

High Efficiency, Open and Enclosed Versions; Fiber Type SM, PM, RC; 780-1625 nm; Fiber Length 40-82 m; Fiber Stretch 3.8-8.0 µm/V; Fiber Leads 1 m, 0.9 mm OD Jacket; Connector Type Bare Fiber, FC/PC, FC/APC The PZ2 series provides the most extensive stretch of Optiphase’s stretcher product family. At the core of the PZ2 high-efficiency fiber stretchers is a fiber wound piezoelectric element for use in a wide range of optical interferometric measurement and sensing system applications. The PZ2 is ideal for use in OCT (Optical Coherence Tomography) and OCDR (Optical Coherence Domain Reflectometry) applications requiring scattering or boundary definition measurements. 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. PZ2 high-efficiency fiber stretchers are available with single mode (SM), commercial polarization maintaining (PM, Panda or Bowtie) or SM reduced cladding (RC) fiber types PZ2 high-efficiency 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 PZ2 high-efficiency fiber stretchers see the downloadable application note.
