Spatial Resolution in Raman Spectroscopy

Confocal Raman Microscope

In Raman microscopy, spatial resolution is vital for discriminating different structures in a sample. The better the spatial resolution the more detailed information can be gained. For example, differentiating different components in a single cell or detecting defects in graphene materials. Lateral and axial resolution are governed by different parameters, however to achieve the highest resolution for both a confocal Raman microscope needs to be used.
