The beam-foil source can be developed as an absolute intensity secondary standard light source. A spectrometer and optical system are calibrated using a standard tungsten filament (blackbody) lamp whose intensity calibration is traceable to the National Bureau of Standards. Knowing the number of photons emitted by the lamp, we determine a wavelength dependent system efficiency. By careful comparison of the intensity of spectral lines emitted from the beam-foil source to an appropriate portion of the continuous spectrum emitted from the standard blackbody lamp, the beam-foil source is calibrated over the same region of the spectrum as is the standard lamp. Branching ratios are then used to extend this calibration into the vacuum ultraviolet.Type
