A radiometric set-up is presented to measure the radiant efficacy of pulsed Xe excimer lamps. It allows time and spectral resolved radiant flux measurements from the VUV to NIR region. The results will provide a better understanding of the plasma processes in Xe excimer lamps. We measure the Xe excimer emission λXe2* = 172 nm in the VUV and spectral lines at λXE* ≈ 828 nm. We use two different monochromators with fast photomultipliers because the duration of Xe excimer micro discharges is only several 10 ns. To determine the total flux of the lamp, we choose a goniometric set-up.
