Preferred Label : spectral photon radiance;
Detailed label : spectral photon radiance, Lpλ;
IUPAC definition : The photon radiance, Lp, at wavelength per unit wavelength interval. The SI unit is
s-1 m-3 sr-1, but a commonly used unit is s-1 m-2 sr-1 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 sr-1 and the common unit mol s-1 m-2 sr-1 nm-1.;
