Figure 2:
Overview spectrum of a Th-Ar lamp. Wavelength range is 715 nm to 5000 nm (14000
cm-1 to 2000 cm-1). The line intensity is given in
arbitrary units. Longwards of 2500 nm (<4000 cm-1) thermal emission
from the hot cathode introduces a continuum in the otherwise pure emission lines
spectrum.
