Gratings
Ruled gratings are made by etching a surface mechanically with a cutting tip, usually diamond.
Holographic diffraction gratings are formed by introducing an interference pattern onto a layer of photosensitive material. The material is then treated with chemicals that only dissolve it where the light interfered constructively. You may also be interested in the Diffraction and Imaging TLP
