Knowledge about the morphology and chemical composition of heterogeneous
materials on a sub-micrometer scale is crucial for the development of
new material properties for highly specified applications. However, each
analytical measuring technique has limitations, which may be overcome by
their combination. Confocal microscopy has been used to reconstruct
three-dimensional images of micro-objects by using a spatial pinhole to
eliminate out-of focus light in specimens thicker than the focal plane.
Raman spectroscopy on the other hand is able to determine the chemical
compositions of materials. The confocal Raman microscope combines Raman
spectroscopy with high resolution confocal microscopy. The
discrimination of out of focus information used in confocal microscopy
is particularly beneficial for confocal Raman imaging since it reduces
the volume from which the Raman spectrum is collected. Due to the
confocal principle, depth information from transparent materials can be
easily obtained, leading to full three dimensional chemical
reconstructions of the material’s composition. The combination of
confocal Raman microscopy with SPM and true surface microscopy permits
characterization of materials at submicron resolution, as well as on mm-
rough surfaces across large areas. Examples from various fields of
applications will be presented.
