A diffraction grating is an optical component ... which often offers a higher efficiency than holographic grating. A ruling engine is equipped with a diamond tool to make grooves on a grating ...

The solution was then cast on a holographic diffraction-grating master mould to obtain free-standing silk gratings with a grating pitch of 600 grooves per millimetre, as shown in Fig. 4.
