Abstract:
Diffuse reflectance spectroscopy apparatus for use in analysing a sample comprising a sample receiving location  2  for receiving a sample  3  for analysis; an illumination arrangement  4  for directing light towards a received sample; a detector  6  for detecting light reflected by a received sample; and collection optics  5  for directing light reflected by a received sample towards the detector. The illumination arrangement further comprises an interferometer  42  and a half beam block  45 a,  45 b  which 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 block  45 a  may be disposed in the optical path between the interferometer and the light source  41  for 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 block  45 b  may be disposed in the optical path on the opposite side of the interferometer than the light source.

Claim (Index 18):
Diffuse reflectance spectroscopy apparatus according to  claim 14  in which the collection optics comprises an intermediate focus position and an aperture is provided at the intermediate focus position and arranged so that its image at the detector has predetermined dimensions chosen to guard against rays outside a chosen angular range reaching the detector, the predetermined dimensions may be chosen in dependence on the dimensions of the light detecting active area of the detector.
