The diffraction gratings capable of analyzing a variety of radiations ranging from soft X-rays to far infrared are now expanding their application areas as optical elements indispensable for spectroscopy.
The diffraction gratings developed by Hitachi have been used in various application areas, and are now highly evaluated as the world’s foremost optical elements.
For example, a total of 36 diffraction gratings having a size of 15 x 15 cm and arranged in a mosaic pattern, are adopted in the large spectrograph used in the Okazaki National Research Institutes, National Institute for Basic Biology.
The spectrograph has successfully realized the world’s largest artificial rainbow whose intensity is 20 times the sunlight energy right above the equator.
Furthermore, the Hitachi plane diffraction gratings consisting of varied space grooves have also been adopted in the spectrometer of the extreme ultraviolet explorer scheduled to be launched by NASA of the U.S.A. Hitachi has developed the reflection plane gratings and concave gratings to meet such most-advanced technological fields as exemplified above.
These gratings are available in a wide variety of models to meet your diversified needs.
