Abstract
Diffuse reflectance spectroscopy apparatus for use in analysing a sample comprising a sample receiving locationfor receiving a samplefor analysis; an illumination arrangementfor directing light towards a received sample; a detectorfor detecting light reflected by a received sample; and collection opticsfor directing light reflected by a received sample towards the detector. The illumination arrangement further comprises an interferometerand a half beam blockwhich is disposed substantially at a focus in the optical path for blocking light which exits the interferometer, passes said focus, and is reflected from re-entering the interferometer. A half beam blockmay be disposed in the optical path between the interferometer and the light sourcefor blocking light that exits the interferometer back towards the light source and is reflected by the light source from re-entering the interferometer and/or a half beam blockmay be disposed in the optical path on the opposite side of the interferometer than the light source.
