ABSTRACT:
A spectrograph for use in analyzing an extended spectral field comprising a dispersive system consisting solely of one or more concave holographic gratings, each grating being specified so that the diffraction spectrum is formed in a plane. Where a plurality of gratings are provided they are formed on a common concave support and are specified so that the planes of the diffraction spectra formed thereby are offset and in total cover the wavelengths of the total spectral field.
