Description
HORIBA Jobin Yvon has produced a wide range of blazed holographic master gratings from which we manufacture high precision replicas.
Our replica gratings retain the advantages of our master holographic gratings:
❏ Perfect periodicity, plus excellent micro-roughness of the surface eliminates ghosts and enhances stray light rejection
❏ Minimal groove errors provide very high resolution
In addition, owing to their ion-etched, sawtooth groove profiles, these gratings offer higher peak efficiency than standard holographic gratings.
