Description
English: Spectrum of a deuterium lamp taken by pointing the light input port (no fiber optic used) of an Ocean Optics HR2000 spectrometer [1] toward the light produced by an ocean optics deuterium lamp. Balmer lines are marked with a "D" since this is deuterium not hydrogen (deuterium alpha on the right at 656nm and the deuterium beta line on the left at 486nm. color of the text roughly corresponds to the color of the emitted light at these wavelengths.). The continuum emission on the far left from 400nm to 200 nm does not actually decrease in intensity from 250nm to 200nm and this is an artefact of the decreased CCD photodetector efficiency at those wavelengths. The continuum actually increases in intensity all the way down to about 165nm where the en:lyman band then dominates emission at lower "vacuum UV" wavelengths. Note that the tallest peak of the Fulcher band and the D-alpha line are saturated to show more detail on less intense lines. Spectrum interpretation was done using information of en:balmer line location, hydrogen emission continuum information found at [2][3] and Fulcher band emission information found at [4]. This spectrum is not calibrated for intensity. Spectrum taken by me.
