Vacuum ultraviolet spectrometer; Ray tracing

Koike, Masato; Sano, Kazuo*

The chapter provides the basic knowledge of "vacuum ultraviolet spectrometers" and "ray racing" for young scientists without reading the numerous references and is intend to be the handbook for the specialist in various related sciences when they initiate spectroscopic experiments in the vacuum ultraviolet region. The content includes the basis of diffraction gratings, Optical properties of diffraction gratings, aberration theories, diffraction efficiency theories, basis of spectrometers, vacuum ultraviolet plane grating spectrometers, vacuum ultraviolet concave grating spectrometers, soft X-ray plane grating spectrometers, soft X-ray concave grating spectrometers, basis of ray tracing, applications of ray tracing, analytic design method, hybrid design method, etc.
