Product information "VAC Fiber Vacuum Pressure Feedthroughs"
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.
