amalgam lamp
Intense source of @UT07492@ (\(185\) and \(253.7\ \text{nm}\)) radiation produced by an electrical discharge in a @L03447@ with the inner side covered by an amalgam of mercury with another element such as indium or gallium to control the vapour pressure of the mercury. These @L03447@ have 2-3 times the UV output for the same @W06659@ as the standard @H02825@.
