OptiLayer:  Your Partner in Design and Post-Production Characterization of Optical Coatings


Change of Colors

OptiLayer allows now to check the change of colors due to:

  • Inhomogeneities/Interlayers;
  • Interface Roughness.

This option is activated by corresponding selection of the setup dialogs. Changes of colors are illustrated graphically at Color diagrams and numerically in all available color spaces.

Additionally the change of Dominant/Complimentary wavelength, Correlated Color Temperature (CCT), Color Rendering Index (CRI) are represented. Also,  the change of Color is presented in terms of CIE DE2000 color change measure.

Example: a 12-layer coating reflecting light of the yellow color from the front side (R) and the light of the blue color from the back side (BR). Left pane: color diagram representing colors of reflected and transmitted light.

error analysis color coordinates

Right pane: refractive index profile. Layer materials: TiO2 (high index material), SiO2 (low index material) and NiCr (metal). At least one metal layer is necessary to achieve different colors of R and BR.

 In Inhomogeneity/Interlayers Setup you should check Include Color Analysis box. There are three different possibilities to specify refractive indices of mixtures. ErrAn InhomSetup

 All H-index layers have -3% bulk inhomogeneity:


ErrAn InhomSetup 2

 Disturbed refractive index profile of the 12-layer design:ErrAn DevProfile

 Deviations of the colors of the reflected light: ErrAn DevDiagr


Deviations of the CRI, CCT and CIEDE2000 can be found in the corresponding spreadsheets:ErrAn DevCRI

 Changes of the Dominant/Complimentary wavelength:
