Popis:	New two devices in a grating spectrophotometer used in the wide wavenumber region are described; one is a slide table system for interchanging gratings and the other a sampling correlator for improving the signal-to-noise ratio. By using these devices, spectra in the linear wavenumber scale were continuously recorded without interruption even during the interchange of gratings and the signal-to-noise ratio was improved by a factor of 2.5.
