Ruled Grating

A type of diffraction grating with a sawtooth profile that is generated by precision mechanical ruling engines. Replicas are then generated by depositing a coating, an epoxy layer, and polished substrate onto the master. Although the gratings are generally cut from larger pieces and have grooves across the entire face, incident light should be confined to 90% of the full face during use.
