Abstract:
1. A sample system investigation system comprising: a) a plurality of electromagnetic radiation sources, each thereof optionally having polarization state setting means functionally associated therewith; b) a means for accepting at least two electromagnetic beams which approach along different loci, and providing an electromagnetic beam which exits therefrom along a single locus; c) a stage for supporting a sample system; d) at least one detector system; said means for accepting at least two electromagnetic beams which approach along different loci, and providing an electromagnetic beam which exits therefrom along a single locus, being positioned with respect to at least two of said plurality of sources of electromagnetic radiation such that a beam of electromagnetic radiation from either thereof, when it is energized, enters thereinto and emerges therefrom along a locus which is directed toward a sample system placed on said stage for supporting a sample system; said at least one detector system being positioned to intercept a beam which emerges from the sample system on said stage for supporting a sample system after said beam of electromagnetic radiation interacts therewith.
