Diffraction Grating Physics. Diffraction Gratings Are Used To Disperse Light; That Is To Spatially Separate Light Of Different Wavelengths. They Have Replaced Prisms In Most Fields Of Spectral Analysis. M = An Integer, And Is The Order Of Diffraction. This Is The Basic Grating Equation. Note That If D Is On The Opposite Side Of The Grating
“The Diffraction Grating Is A Useful Device For Analyzing Light Consists Of A Large Number Of Equally Spaced Parallel Slits.”Its Working Principle Is Based On The Phenomenon Of Space Between Lines Act As Slits And These Slits Diffract The Light Waves Thereby Producing A Large Number Of Beams Which Interfere In Such A Way To Produce Spectra.
Diffraction Grating Physics. Figure 4: The Sign Convention For The Angle Of Incidence, Angle Of Diffraction And Grating Angle. W = Illuminated Width Of The Grating. Normally The Smallest Slit Available And Optical Aberrations, Rather Than The Grating, Determine The Attainable Resolution.
A Typical Diffraction Grating Consists Of A Substrate, Usually Of An “optical Material”, With A Large Number Of Parallel Grooves Ruled Or Replicated In Its Surface And Overcoated With A Reflecting Material Such As Aluminum.
In Optics, A Diffraction Grating Is An Opticalponent With A Periodic Structure That Splits And Diffracts Light Into Several Beams Travelling In Different Directions. The Emerging Coloration Is A Form Of Structural Coloration. The Directions Of These Beams Depend On The Spacing Of The Grating And The Wavelength Of The Light So That The Grating Acts As The Dispersive Element.

The Experimental Setup Is Very Simple And Consists In Pointing The Beam Laser Emitted From The He-Ne Source On The Diffraction Grating. The Beam Undergoes Diffraction And Produces On The Screen Behind The Grating The Diffraction Pattern With The First And Second Order Maxima.

Holographic Gratings From Gratingworks Have A Groove Density From 40 To 6000lines/mm And Cover A Wavelength Range From Fringe Profiles Of Gratings Can Be Sinusoidal, Deformed Sinusoidal, Or Triangular. Their Diffraction Efficiency Is From 30% To 85% At Their Optimized Wavelength. If Only TM Polarization Is Desired, The Diffraction Efficiency Can Reach 95%.
