Open Live Script

Load the optical coating library into the workspace.

cl = coatingLibrary
cl = 
  CoatingLibrary with properties:

    CoatingCatalogTable: [1×3 table]
               Coatings: [2×1 opticalCoating]

Display the two default optical coatings in the coating library.

braggOc = cl.Coatings(1)
braggOc = 
  opticalCoating with properties:

                  Name: "Bragg_587nm_12l"
    IncidentAngleRange: [0 15]

Add New Coatings to Coating Library

Create a broadband anti-reflective (AR) optical coating that consists of two alternating TiO2/SiO2 material layer stacks.

ocBBAR = opticalCoating(Name="BBAR_4l", ...
    CoatingMaterial=["TiO2", "SiO2"], ...
    LayerMaterialIndex=[1 2 1 2], ...
    ThicknessUnit="nm", ...
    LayerThickness=[14.6 36.5 129.1 95.5])
ocBBAR = 
  opticalCoating with properties:

                  Name: "BBAR_4l"
    IncidentAngleRange: [0 15]
       WavelengthRange: [300 800]
     PrimaryWavelength: 587.5618
                Medium: [1×1 opticalMaterial]
             Substrate: [1×1 opticalMaterial]
      CoatingMaterials: [2×1 opticalMaterial]
    LayerMaterialIndex: [1 2 1 2]
        LayerThickness: [14.6000 36.5000 129.1000 95.5000]
         ThicknessUnit: "nm"
             NumLayers: 4
        TotalThickness: 275.7000

Create another Bragg reflector coating.

ocBragg = opticalCoating(...    
    Name="Bragg_500nm_12l", ...
    CoatingMaterials=["SiO2", "TiO2"], ...
    PrimaryWavelength=500, ...
    LayerMaterialIndex = repmat([1 2], [1 6]), ...
    ThicknessUnit = "quarterWavelength", ...
    LayerThickness = ones(1,12));

Add the new broadband AR and Bragg coatings to the coating library.

addCoating(cl,[ocBBAR ocBragg])

Display the updated coating library.

cl
cl = 
  CoatingLibrary with properties:

    CoatingCatalogTable: [2×3 table]
               Coatings: [4×1 opticalCoating]

Remove Coating From Coating Library

Remove the newly added Bragg reflector from the coating library.

removeCoating(cl,"Bragg_500nm_12l")

Restore Default Coating Library

To revert the changes and restore the coating library to its default state, use the restoreDefaultCoatingLibrary function.

restoreDefaultCoatingLibrary

Input Arguments

collapse all

Coating library to which to add a coating material, specified as a CoatingLibrary object.

Name of the optical coating to remove from the coating library, specified as a string scalar or character vector.
