Swagelok Ultra-Torr based feed-through design for coupling
optical fibre bundles into vacuum systems

Cowpe, JS; Pilkington, RD

Abstract

We report the design of an inexpensive and flexible fibre-optic bundle high vacuum feed-through that
can be constructed from easily available Swagelok Ultra-TorrTM stock parts. The fibre bundle extends
through the vacuum envelope and thus does not suffer the transmission losses encountered when using
face-to-face couplings. The flexibility of construction allows the fitting to be customised to suit all flange
designs such as CF, KF or custom mountings. The use of VitonTM o-rings allows modest baking (max
200 C) for high vacuum applications and fibre bundles can be easily repositioned, removed or replaced.
