Paper Abstract

A spectrometer system, based on the Multi-Echelle Grating Arrangement (MEGA) (1) has been developed. Through series diffraction in an even number of echelle gratings, high dispersion and spectral resolutions are obtained. It can be shown (1) that with n gratings of width W, utilized in a MEGA-spectrometer of focal length f, the same resolution and dispersion is obtained as in a conventional spectrometer with a grating width nW and a focal length nf.
