Resumo

Diffraction gratings in which the grooves are formed by recording optical interference fringes are rapidly becoming established as alternatives to ruled gratings. In many respects they compare favourably with ruled gratings, but because of both the limitations and the novel features of the interference method of manufacture, a straightforward comparison is not always possible. Whether a ruled or interference grating is to be preferred will strongly depend upon the use to which it is to be put.
