Outline of Final Research Achievements	Semiconductor devices such as LED’s are promising ones for not only visible but also ultraviolet (UV) region. However, in order to know the optical properties of the material used in UV, it is necessary to investigate even higher energy region, vacuum ultraviolet light (VUV). Then, we construct a spectrometer system that can measure light including polarization characteristics even at VUV, and aimed using this system at the synchrotron radiation facility which is the ideal ultraviolet light source. As a result, the construction of the spectrometer has been reached nearly complete.
