Diffraction Gratings

Thorlabs' diffraction gratings, which are used to separate light into component wavelengths, are offered in both transmission and reflective varieties for use from the UV to the MIR. Our diffraction grating selection includes ruled (blazed), volume phase holographic, holographic, echelle, and a grating modulator. See the Gratings Tutorial and Gratings Guide tabs on the pages below for more information on diffraction grating performance and selection.
