介绍了一种廉价的可烘烤超高真空兼容金属密封光纤馈线的设计和性能。机械加工的铝插头取代了未改装的世伟洛克不锈钢压缩接头的前卡箍，对七根平行的铝套石英光纤进行密封。我们发现，这种设计在重复烘烤到250cm3°C后，可以达到10−9 cm~3/分钟氦的密封性。可以通过拆卸光纤和插头组件来拆卸馈送通道，然后重新组装，而不会造成泄漏。
We describe the design and performance of an inexpensive bakeable ultrahigh vacuum-compatible metal-sealed optical fiber feedthrough. A machined aluminum plug replaces the forward ferrule of an otherwise unmodified Swagelok stainless steel compression fitting to make a seal to seven parallel aluminum-jacketed quartz optical fibers. We have found this design to be leak tight to 10−9 cm3/min helium after baking repeatedly to 250 °C. The feedthrough my be disassembled by removing the fiber-and-plug assembly and then reassembled without creating leaks.
