double-beam spectrometer (for luminescence spectroscopy)

https://doi.org/10.1351/goldbook.D01842
Double (spectral) beam spectrometers are used where two samples are to be excited by two different wavelengths. A double- (@S06219@) beam @S05837@ is a @L03645@ in which both the excitation and emission monochromators scan the excitation and emission spectra simultaneously, usually with a fixed @W06659@ difference between excitation and emission.
