Abstract:
A light source arrangement for conducting spectroscopic analysis of a material to be analyzed, the light source arrangement comprising:a first source of electromagnetic energy, said first source issuing a first source electromagnetic energy having a first predetermined spectroscopic characteristic; a second source of electromagnetic energy, said second source issuing a second source electromagnetic energy having a second predetermined spectroscopic characteristic; a first port for emitting an output electromagnetic energy having an output spectral characteristic responsive to a selectable combination of said first and second predetermined spectroscopic characteristics; a holder for holding the material to be analyzed in a first path of propagation of the output electromagnetic energy; a second port for emitting a second output electromagnetic energy having a second output spectral characteristic responsive to a second selectable combination of said first and second predetermined spectroscopic characteristics; and a third port for emitting a first test electromagnetic energy having a first test spectral characteristic responsive to an interaction between the output electromagnetic energy and the material to be an analyzed.
