The diffraction gratings developed by Hitachi have been used in various application areas and are now highly evaluated as the world's foremost element. Hitachi's highly reputed precision-ruling engine has now been combined with laser interferometric technology. This permits arranging the groves to a nanometer precision! Our burnishing technique, with use of a diamond tool, enables forming excellent grooves, making surfaces far smoother than vacuum evaporated metal surfaces.
Plane, Concave, or CUSTOM-designed diffraction gratings with a choice of blank material and coating:
