Diffraction Gratings

Laminar Gratings for the vacuum ultra violet region

Using the holographic exposure method and ion-beam etching technology, Shimadzu has developed laminar gratings that can be used for spectroscopy in a range from the vacuum ultraviolet region to the soft X-ray region. These diffraction gratings have grooves with a rectangular profile, which are directly etched into blanks made of, for example, synthetic silica. (Refer to Fig. 6.) Laminar gratings are recommended for applications involving oblique light incidence.
