  • Abstract
    Many atomic physics and frequency metrology applications require nonmagnetic optical viewports for ultra high vacuum (UHV) chambers. We have refined two techniques for producing specialized UHV optical viewports. The first is a weld-in window cell made by brazing an optical blank into a thin weld collar. The second is a mechanical sealing method that relies on crushing a series of thin copper knife-edges
