A compact soft X-ray emission spectrometer for the energy region of 50-600 eV has been designed and constructed for the long undulator beamline BL-09A in the NewSUBARU synchrotron radiation (SR) facility. The optical design of the spectrometer is based on a grazing incidence flat-field spectrometer using a valid line-spacing grating. The average groove density of the grating is 2000 L/mm, and the angle of incidence to the grating is 86.5 deg. The distances from the slit to the grating and from the grating to the CCD are 355 mm and 650 mm, respectively. The energy resolution, E/ΔE, was estimated to be greater than 1000 in the energy range of 50-600 eV. Spectra of K-emission X-rays of several light elements, such as B, C, N, and O, from various samples were successfully obtained.
