The key optical element is called a diffraction grating, an important tool in optical analysis. However, most modern-day applications of slit interference use not just two slits but many, approaching infinity for practical purposes. Discuss the pattern obtained from diffraction gratingsĪnalyzing the interference of light passing through two slits lays out the theoretical framework of interference and gives us a historical insight into Thomas Young’s experiments.These gratings are very effective for the application of soft x-rays whose reflectance is extremely low on a metal surface.By the end of this section, you will be able to: Highly dispersive concave gratings for grazing-incidence mounting are available especially used for synchrotron radiation and extreme ultra-violet applications. Diffraction gratings for multi wavelength optical communication:Ī compact and efficient aberration corrected concave grating is manufactured for transmitting multiple wavelength light beams through an optical fiber and acts to separate the beams at the receiving terminal.Gratings are designed optimally for the grazing-incidence optical system (for soft X-ray) and the normal incidence optical system (for VIS-UV ray), respectively. The spectrograph permits simultaneous measurement of multi-wavelength spectra when combined with a linear array detector. Variable space grooves enable flat-field image focusing of concave grating spectrograph. Diffraction gratings for flat field spectrograph:.

These gratings are designed for normal incidence mounting.　They reduce aberrations and at the same time increase the efficiency of light intensity.Ī as a result, a high quality of image focusing of the concave grating is available.

Diffraction gratings for compact, high efficiency monochromator:.

Hitachi is manufacturing a wide variety of aberration-corrected gratings for Seya-Namioka monochromator which cover a wavelength range from the vacuum ultra-violet to the near infrared region.

This grating eliminates the coma-type aberration of the Seya-Namioka monochromator, which has been most widely used in monochromators with concave gratings that provide high resolution. Coma-type aberration-corrected concave grating for high resolution Seya-amioka monochromator:.These gratings are available in a wide variety of models to meet your diversified needs. Hitachi has developed the reflection plane gratings and concave gratings to meet such most-advanced technological fields as exemplified above. The spectrograph has successfully realized the world's largest artificial rainbow whose intensity is 20 times the sunlight energy right above the equator.įurthermore, the Hitachi plane diffraction gratings consisting of varied space grooves have also been adopted in the Spectrophotometers of the extreme ultraviolet explorer scheduled to be launched by NASA of the U.S.A. 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.įor example, a total of 36 diffraction gratings having a size of 15 × 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 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.
