Preferred Label : spectral photon flux;
Detailed label : spectral photon flux (photon irradiance), Epλ;
IUPAC definition : The photon irradiance E p, at wavelength λ per unit wavelength interval. The SI unit
is s-1 m-3, but a commonly used unit is s-1 m-2 nm-1. Alternatively, the term can
be used with the amount of photons (mol or its equivalent einstein), the SI unit then
being mol s-1 m-3 and the common unit mol s-1 m-2 nm-1.;
