A diffraction grating is produced by first ruling a master grating. We can then replicate this master into a large number of exact copies, called replicas, for cost savings and product consistency.

Master gratings are manufactured using the following technologies:

• Holographic recording

• Ion-etching of holographic master

• Mechanical ruling
