- A deuterium arc lamp (or simply deuterium lamp) is a low-pressure gas-discharge light source often used in spectroscopy when a continuous spectrum in the ultraviolet region is needed. Plasma "arc" or discharge lamps using hydrogen are notable for their high output in the ultraviolet, with comparatively little output in the visible and infrared. This is similar to the situation in a hydrogen flame. Arc lamps made with ordinary light-hydrogen (hydrogen-1) provide a very similar UV spectrum to deuterium, and have been used in UV spectroscopes. However, lamps using deuterium have a longer life span and an emissivity (intensity) at the far end of their UV range which is three to five times that of an ordinary hydrogen arc bulb, at the same temperature. Deuterium arc lamps, therefore, despite being several times more expensive, are considered a superior light source to light-hydrogen arc lamps, for the shortwave UV range. (en)
- La lámpara de deuterio (o lámpara de descarga de deuterio) es una fuente de luz compuesta por una cápsula de cristal ultravioleta, o de cuarzo, que contiene deuterio a baja presión en su interior. Suelen emplearse en espectrometría como espectro continuo de referencia de la región ultravioleta, así como para generar la señal de análisis en cromatógrafos. (es)
