A Fourier-transform optical spectrometer is provided with means (50) for restricting the bandwidth of light incident on a detector (36) for the spectrometer output to a smaller bandwidth than that transmitted from a light source (30) providing the spectrometer illumination. It is then possible to increase the source brightness to enhance the detector signal without saturating the detector. As a result the signal to noise ratio can be increased.
