Abstract:

The conditions for applicability of the Bouguer-Lambert-Beer law for aerosol clouds with particles much larger than the photon wavelength are derived in the form of an analytical formula. The corrections to this law due to diffraction scattering and the geometry of a measuring device are estimated. The resulting formula is useful for processing single experiments that cannot be repeated for some reason.
