The use of two separated diffraction gratings or prisms doubles the spectroscopic resolution compared to that obtained with a single equivalent grating or prism. Ultra-high resolution is possible with widely spaced gratings. Varying the spacing between the two gratings or prisms produces useful modulation in the spectrum.
