Indices Correction Model
Indices Correction option is purposed for the post-production characterization of layer refractive indices. For various reasons layer refractive indices in a multilayer stack may vary from the corresponding indices being determined from single layer measurements and then used for the computations of optical coating designs. The Indices Correction option allows for the determination of practical indices more accurately and thus provides a feedback to the design procedure. The following refractive index and extinction coefficients models are available:

The Index drift models allow you to include into consideration possible drifts of the refractive indices of layer materials:
\[ \delta n_j=C\exp(-\alpha j)\] Exponential type of drifts usually provides large deviations at the beginning of deposition that are rapidly decreasing with the layer number. |
