WebLuminous flux Φ v is the basic photometric quantity and describes the total amount of electromagnetic radiation emitted by a source, spectrally weighted with the human eye's spectral luminous efficiency function V (λ). Luminous flux is the photometric counterpart to radiant power. The unit of luminous flux is lumen (lm), and at 555 nm, where ... WebAnother equally important aspect concerns the transmission of solar radiation through the atmo- sphere and its fluctuations. In studies of this nature, it becomes necessary to distinguish between energy scattering and absorbing mechanisms. ... . 1962a.
