Variable Field of View Fourier Transform Infrared Spectroscopy

Volume 31, Number 1 (Feb. 1977) Page 42-43

Hirschfeld, T.; Fateley, W.G.


For samples showing appreciable fluorescence emission spectra, the effective transmission, neglecting sample reflectance, and for not too strong absorption, is given by

Te = T + (1 - T)QFΩE/4π

where Te and T are the effective and actual transmission, respectively; QF is the fluorescent quantum efficiency, Ω the solid angle of light collection following the sample, and E is the collection efficiency of the interferometer.
