WebCustom Diffraction Gratings In optics, a diffraction grating is an optical component with a periodic structure that splits and diffracts light into several beams traveling in different directions. The directions of the beams depend on the spacing of the grating and the wavelength of the light so that the grating acts as the dispersive element. Because of this, … When choosing a grating it is important to specify the wavelength range, blaze wavelength (which is the wavelength in the diffracted spectrum … See more Edmund Optics® offers a wide range of diffraction gratings spanning the entire range of options discussed above.

WebA diffraction grating is a passive optical component that redirects light incident upon the surface at an angle that is unique for every wavelength in a given order. This redirection (or diffraction) is a result of the phase change of the electromagnetic wave as it encounters the regular, fixed structure of the grating surface.
