http://depthome.brooklyn.cuny.edu/physics/lab/phy2/newlabs/Diffraction-grating-ver-2.pdf 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. dr miletic michiganWebThe grating equation mλ=d (sinα + sinβ) can be differentiated to give the angular spread (dispersion) of the spectrum: dβ/dλ = (sinα + sinβ) / λcosβ When the grating is operated in the Littrow configuration (in which the light is retro-diffracted; see Figure 2), the equation for the dispersion simplifies to: dβ/dλ = 2tanβ / λ coldwell banker durant ok
