Lamp emission spectra measured with a LI-COR LI-1800
spectroradiometer. Member spectra containing the wavelengths at a 0.5 nm,
1.0 nm, or 2.0 nm interval and tabulated values of spectral irradiance for
different lamps. As absolute values are not meaningful because measuring
distances are in most cases unknown data have been normalized to one at the
wavelength of maximum energy irradiance.
