Plane Ruled Diffraction Gratings Are Blazed For Maximum Efficiency In The First Order Littrow Configuration At Specific Wavelengths. Ruled Reflection Gratings Are Especially Well Suited For Spectroscopic Systems Requiring High Resolution. High Efficiency At Design Wavelength And Blaze Angle
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 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.

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%.
A Holographic Diffraction Grating Is Produced Using A Photolithographic Technique. The Mostmon Type Of Diffraction Grating Are Plane Gratings And Concave Gratings Although They Can Also Be Other Profiles Such As Convex Or Toroidal Depending On The Application. Spectrum Scientific Offers A Wide Range Of Holographic And Ruled Diffraction
Diffraction Produces The Entire Spectrum Of Colors As The Viewing Angle Changes, Whereas Thin-film Interference Usually Produces A Much Narrower Range. The Surfaces Of Flowers Can Also Create A Diffraction, But The Cell Structures In Plants Are Usually Too Irregular To Produce The Fine Slit Geometry Necessary For A Diffraction Grating.
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.

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.

Diffraction Grating Physics. Diffraction Gratings Are Used To Disperse Light; That Is To Spatially Separate Light Of Different Wavelengths. Figure 4: The Sign Convention For The Angle Of Incidence, Angle Of Diffraction And Grating Angle. If The Angle D Is Equal To I And Of Opposite Sign, Then The Grating Angle And Order Are Zero, And The
