WebAug 10, 2024 · The deuterium lamp is a high pressure gas discharge lamp that produces useful radiation over the range from 160 nm to 380 nm. A picture of a deuterium lamp is shown in Figure 7.2.3 and the spectral output of this lamp is shown in Figures 7.2.4. The light from a deuterium lamp is randomly polarized and incoherent. WebThe explanation comes from the band theory of the solid state: in metallic solids, the electronic energy levels of all the valence electrons form bands of zillions of energy levels packed really closely together, with the electrons essentially free to …
