McPherson, Inc. The Model 629 Hollow Cathode Light Source is a continuous gas discharge source that can be used with molecular or rare gases. It is electrically quiet and is a rich source of vacuum ultraviolet (VUV) spectral lines (to at least 20-nm (62-eV.) The source is a Schueler-type lamp which produces strong ion lines. It differs principally from a capillary discharge source in that the negative glow of the discharge is viewed directly, rather than through the positive column of neutral gas.
