In order to investigate the spectra of rare-gas halide lasers, a 1-m concave grating spectrograph for vacuum ultraviolet of the modified Eagle type has been designed and constructed. The spectrograph is capable of measuring the spectra in the wavelength region from 1000 Å to 8000 Å, which corresponds to that found in the stimulated emission spectra of rare-gas halide lasers. Adjustments of the grating and the film holder are possible without breaking the vacuum. For the test of this spectrograph, the spontaneous emission spectra of the ArF excimer (B^2Σ^+-X^2Σ^+) in the first order and of the N_2 second positive system (C^Π_u-B^3Π_g) in the second order have been measured with the result of obtaining the resolving power estimated at about 4×10^4 in the N_2 spectrum.
