Paper Abstract

FTIR spectrometers generate a beam of finite area and convergence. Appropriately located variable apertures can be used to control both the area and the convergence of the beam. We have used a spectrometer fitted with such apertures to investigate their effect on transmission and reflection spectra. Perhaps the most significant finding is that the relative intensities of bands in an ATR spectrum can be altered by more than 10% simply by varying the beam convergence.
