spectral bandwidth error

in spectrochemical analysis
https://doi.org/10.1351/goldbook.S05812
To measure the true shape, particularly the true maximum of an absorption band, the spectral bandwidth \(\Delta \lambda \) of the instrument must be much less than the width of the absorption band. A spectral bandwidth error results from using too large a bandwidth relative to the absorption band being measured.
