Holographic plane gratings

OEM gratings design and production capabilities

HORIBA Scientific produces a wide range of holographic master gratings from which high precision replicas are manufactured.
A plane type of grating is the choice for high resolution spectroscopy and applications where low stray light levels are of high importance.
