Ruled Diffraction Gratings
The initial step to make an original or master grating is to select the substrate material, usually usin glass or copper. The substrate material is polished to a high flatness and coated with very thin aluminum. The parallelism and equidistance of the grooves takes time to adjust. A few days is required to set up and test before engraving. The engraver must make sure the diamond knife head can return back in a precise way after each engraving and can engrave the substrate based on the quantity on schedule. The parallelism and displacement of the grooves must be precisely controlled. Engraving requires a series of tests. After testing passed, the original grating can be carved on a large substrate. The original grating is very expensive, so the grating can only be used limited until the replica grating is developed.

Precautions:
Optical gratings can be easily damaged by moisture, fingerprints, aerosols, or the slightest contact with any abrasive material. Gratings should only be handled when necessary and always held by the sides. Latex gloves or a similar protective covering should be worn to prevent oil from fingers from reaching the grating surface. No attempt should be made to clean a grating other than blowing off dust with clean, dry air or nitrogen. Solvents will likely damage the grating's surface.
