  The quality of astronomical spectra is now so high that the accuracy of the
laboratory data is getting more and more important for the analysis and
interpretation. Both in astrophysics and cosmology the needs for accurate
laboratory wavelengths have increased with the development of new ground-based
and air-borne telescopes and spectrographs. The high resolution UV Fourier
Transform spectrometer at Lund Observatory is being used for studying
laboratory spectra of astrophysically important elements. Measurements of
accurate laboratory UV and IR wavelengths have been made for cosmological and
astrophysical applications.
