Automatic Correction of Fluorescence Spectra for Primary and Secondary Inner-filter Effects (IFE) with Duetta by HORIBA

Three-page manufacturer technical note. Page 1, Introduction and Figure 1: attenuation before the observation region and absorption of emitted light before detection. Equation 2 gives an absorbance-based correction; its applicability depends on geometry. Numerical model in the article is an explicitly derived centre-view approximation, not a reported experiment. Caption inconsistencies noted in the worker report; no disputed figure concentrations are used.
