Blazed Holographic Plane Gratings
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-rough-ness 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.
Typical Blazed Holographic Plane Grating Efficiencies - Efficiency Curves
- 530 13, 2400 l/mm, 190-700 nm
NOTE:
These efficiency curves are absolute theoretical efficiencies, calculated using rigorous electromagnetic theory, taking into account the true groove profiles of manufactured gratings measured with an atomic force microscope (AFM).
These curves are for reference only and do not indicate grating specifications.
