Distance between the blades of the entrance or exit slits in a monochromator.

Note: Spectral slit width is the range of wavenumbers/wavelengths or frequencies that the physical slit widths allow to be passed by the monochromator and is often determined as the full width at half maximum measured by the instrument for a line that is known to be extremely sharp.
