VAC Fiber Vacuum Pressure Feedthroughs OZ Optics Datasheet

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.

Wisemotion Oil-Free Linear Compressors

The Wisemotion compressors have a linear motor that drives the piston directly and are made of parts that do not need lubrification. Capacity is controlled by stroke at a virtually constant frequency. Its extremly quick response time and the oil-free circuit make them suitable for high performance micro channel evaporators that can be used to cool laser diodes.

VFT Fiber Vacuum Pressure Feedthroughs

Single Channel; Fiber Type Step Index Multi Mode; Core Size 200 to 600 µm; Flange Options Bolt, Conflat & ISO Klein Flange; Connector Type SMA905 Fiberguide’s VFT series of fiber vacuum pressure feedthroughs is designed to allow optical fibers to penetrate a pressure vessel without compromising the integrity of the vacuum. The VFT series can be configured as stand-alone feedthroughs or integrated into cable assemblies as needed. The VFT series of vacuum feedthroughs are ideal for laser power delivery or optical sensing applications that must be conducted in a pressure or vacuum chamber. Optional specifications for the VFT series of vacuum feedthroughs are pigtail or bundle configurations, alternate connectors or fiber types as well as variants for high or low temperature. Key Features: Fiber Type: Step Index Multimode Core Sizes: 200, 400, 600 µm Wavelengths: 190 to 1250 (High OH), 300 to 2400 nm (Low OH ) Numerical Aperture (NA): 0.22 Connector Options: SMA905 Flange Options: Bolt Style, ConFlat Flange, ISO Klein Flange (KF) Bulkhead Temperature Range: -40 to +125 °C Vacuum Rating: 1 x 10-9 Torr Applications: Laser Power Delivery or Optical Sensing in a Pressure or Vacuum Chamber
