These feedthroughs are designed for use with fibre optics in vacuum chambers, such as for plasma and coating deposition monitoring. They can be used in chambers with wall thicknesses of 5-40mm and vacuum levels up to 10-7 millibar.
The feedthrough assembly consists of an M12 housing with Viton® O-ring and two SMA fibre-optic interconnects to allow easy coupling to fibre-optic cables and probes. In order to connect these assemblies to fibre-optic cables inside/outside the chamber, two extra SMA fibre interconnects (ME-FI-SM-MM) should be ordered separately.
The vacuum feedthrough can be delivered for all fibre diameters, from 50 μm up to 1000 μm for UV/VIS/NIR. A high-temperature version of the vacuum feedthrough (-HT) is also available, enabling the device to withstand temperatures up to 200°C.
