The deuterium lamp emits radiation extending from 112 nm to 900 nm, although its continuous spectrum is only from 180 nm to 370 nm. The spectrum intensity does not actually decrease from 250 nm to 200 nm as shown in the spectrum plot above. The decrease in the plot is due to decreased efficiency at low wavelengths of the photo detector used to measure the lamp intensity. The deuterium lamp's continuous spectrum is useful as both a reference in UV radiometric wor… WebA deuterium lamp is used over the wavelength range 185 to 340 nm and a tungsten-halogen lamp is used over the wave- length range 340 to 3150 nm as a source. ... instrument's deuterium lamp and the emission spectrum of a mercury pen lamp [6,7,8].
