Abstract

A space-resolved spectrum was obtained using a flat-field XUV spectrograph system, composed of a varied line-spacing concave grating, a toroidal mirror, and a 40 micrometer- width slit. The toroidal mirror is used in order to compensate for the astigmatism due to the grazing incidence of light at the grating. The spectral resolution of the spectrograph system was measured with the XUV spectra emitted from laser plasma produced by an iodine laser. The spatial resolution of the spectrograph system was obtained by calculating transverse ray aberrations with the wave front aberration for the system.
