Characterization of a grazing incidence spectra-imager laboratory model for solar observation

This thesis describes the work made on the optical characterization of a laboratory demo-model stigmatic grazing-incidence spectra-imager for solar investigation. This instrument, stigmatic in an extended field of view, can acquire spectral features between 4 nm and 20 nm, even preserving spatial information. The system consists of a double telescope in the KirkPatrick-Baez configuration and a grazing incidence spectrograph
