Spectrum
The deuterium (D2) lamp is designed for use in spectroscopic applications where high intensity
and stability in the 190 to 400nm band are needed. Above 400nm, some spiky spectra will be detected
also.
The Tungsten-halogen light source is a well-known near-black body radiation source. Its
spectrum is also very similar to those of black body radiation.
