Diffraction Gratings
Advanced Technologies for Grating Production
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
