Grate \Grate\, v. t. [imp. & p. p. {Grated}; p. pr. & vb. n.
{Grating}.]
To furnish with grates; to protect with a grating or
crossbars; as, to grate a window.
[1913 Webster]

a latticework resembling a window grate; as, the grating
of a prison or convent.
[1913 Webster]

2. (Optics) A system of close equidistant parallel lines or
bars, esp. lines ruled on a polished surface, used for
producing spectra by diffraction; -- called also
{diffraction grating}.

Note: Gratings have been made with over 40,000 such lines to
the inch, but those with a somewhat smaller number give
the best definition. They are used, e. g., to produce
monochromatic light for use in optical instruments such
as spectrophotometers.
