* For slits with widths of 50 µm or less, aberrations begin to play a role in the actual achievable
resolution. The values noted above, unless otherwise stated, are calculations based on the slit
widths and grating dispersions.
** Empirically measured resolution values shown which differ from calculations due to aberrations
present when using narrow slit widths.
