Footnotes

  1. Depending on the choice of laser, a minimum width may apply to prevent damage to the gratings.
  2. Wavelength change corresponding to a minimal adjustment of the grating motor. Highly grating dependent, upper bound for standard gratings given.
  3. Filtering wavelength accuracy. Features of source laser can distort the spectral shape of the output.
