How we can calculate the Spatial and Spectral Resolution of a Raman Spectrometer?? What the factors influencing these resolutions??
what are the major parameters influencing the Spectral resolution of Raman spectrometer and How we can calculate it for a particular spectrometer.
How it differs from spatial resolution ??
How we can improve the spatial and spectral resolution of Raman Spectrometer ?
The spatial resolution is largely determined by the laser beam profile, the wavelength and the delivery objective (usually microscopic). Thus it is independent of the spectrometer (or Raman effect) itself, and is governed by the focussing conditions. Improved spatially can be achieved microscopically by including a confocal hole.
The spectral resolution depends on the configuration of the spectrometer illumination, the grating dispersion, the spectrometer length (from grating to detector), and either exit slit or, in the case of CCD, the pixel size.
Spatial and spectral resolution can be treated largely independently and described by simple microscope or spectrometer theory.
