We have developed a spectrometer specialized for a simultaneous high-resolution measurement of emission spectra of the hydrogen atomic Balmer-α, -β, -γ lines and molecular Fulcher-α (v = v = 0) and (v = v = 2) ro-vibronic bands, where v and v is the vibrational quantum number. The instrumental widths for the respective wavelength ranges are 0.008, 0.009, 0.010, 0.008, and 0.007 nm. We apply the spectrometer to the observation of emissions from a LHD plasma. The observed profiles of these emission lines and bands show polarization dependence. The absolute intensities of these emissions are also estimated.
