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