Diffraction grating: A glass substrate carrying a layer of deposited aluminum that has been pressure-ruled with a large number of fine equidistant grooves, using a diamond edge as a tool. Light falling on such a grating
is dispersed into a series of spectra on both sides of the incident beam, the angular dispersion being inversely proportional to the line ***cing. By proper shaping of the diamond edge, however, the grooves can be formed in such a way as to concentrate most of the energy into a single spectral order; such a grating is said to be blazed.
Cast replica gratings can be made in plastic or another substrate, the replica being used either as a transmitting grating or by
aluminizing it, as a reflecting grating. Plane gratings require external optics to focus the spectral lines, but a grating ruled on a concave surface is self-focusing. See concave grating.
