Web2.2.1 SPECTRAL RADIANCE The radiance of a light source is a single value which is the sum of all energy measured over a spectrum. The individual energy values at a particular wavelength in nanometer (nm) can be determined by a spectral radiance measurement. The SI units for spectral radiance is Watt/square meter Steradian nanometer (Watt/m2 sr nm). WebIn radiometry, radiant flux or radiant power is the radiant energy emitted, reflected, transmitted, or received per unit time, and spectral flux or spectral power is the radiant flux per unit frequency or wavelength, depending on whether the spectrum is taken as a function of frequency or of wavelength. laukaus https://lostinshowbiz.com
