Description
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.
ㆍ Replica gratings from master holographic gratings
ㆍ Perfect periodicity and excellent microroughness
ㆍ Elimination of ghosts and low stray light
ㆍ Substrate materials: Fused silica, Zerodur, Pyrex…
ㆍ Large range of groove densities: from 150 to 5670gr/mm
ㆍ Multiple spectral range: from UV to NIR
ㆍ Available dimensions: many references up to 120x140x20mm
ㆍ Coating: Al.

Fig. 2: Typical efficiency curve* for 520 25, 1200 l/mm, 190-800 nm
*This efficiency curve is absolute theoretical efficiency, calculated using rigorous electromagnetic theory, taking into account the true groove profiles of manufactured gratings measured with an atomic force microscope (AFM).
