When there is a need to separate light of different wavelengths with high resolution, then a diffraction grating is most often the tool of choice. This "super prism" aspect of the diffraction grating leads to application for measuring atomic spectra in both laboratory instruments and telescopes.

A diffraction grating is the tool of choice for separating the colors in incident light ... However, angular separation of the maxima is generally much greater because the slit spacing is so small for a diffraction grating.
