The FC-VFT vacuum feedthroughs are designed for use of fiber optics in vacuum chambers, such as for plasma monitoring.
The vacuum feedthrough consists of an M12 housing with Viton® O-ring and 2 SMA fiber optic interconnects to allow easy coupling to fiber optic cables and probes (2 extra SMA fiber interconnects ME-FI-SM-MM need to be ordered separately).
The vacuum feedthrough can be delivered for all fiber diameters, such as 50 µm up to 1000 µm for UV/VIS as well as for VIS/NIR.
