Diffraction Gratings

A diffraction grating is used to spatially separate light of different wavelengths. A typical diffraction grating consists of an optical material substrate, with a large number of parallel grooves ruled or replicated in its surface and overcoated with a reflecting material such as aluminum. We offer diffraction gratings from Richardson Gratings™, a world leader in the design and manufacture of diffraction gratings for spectroscopic, telecommunications and laser applications. Please see our Grating Physics tutorial for additional information.
