Abstract:
1. A system for monitoring samples comprising: a source of spectroscopic electromagnetic radiation; a means for supporting a sample; a reflecting means; a detector of spectroscopic electromagnetic radiation; and an intensity controlling filter means; said source and detector being mounted to a common support and laterally offset from one another, such that in use an incident beam of electromagnetic radiation from said source thereof is caused to approach a sample placed on said means for supporting a sample at an intended angle of incidence along a first locus, reflect from said sample, interact with said reflecting means and proceed along a selection from the group consisting of: again interact with said sample and re-reflect therefrom at the intended angle of incidence, then proceed along a second locus and enter said detector; and proceed along a second locus and enter said detector; said beam also being optionally caused to pass through said intensity controlling means.
