Refractive-Index Fitting How-To​

This guide covers common preparation steps before running a refractive-index fit. You will learn how to reuse saved configurations and how to set the measurement environment correctly.

How to reuse previous index configurations​

Refractive-index fitting requires many initial parameters (substrate, optimizer settings, bounds, etc.). If you have a previously saved configuration that worked, import it to avoid re-setting everything.

提示

Before starting a new fit, we strongly recommend downloading the closest preset template and then fine-tuning it. This can save up to ~80% of setup time.

Download a saved configuration​

  1. Open the right-side drawer by hovering near the right edge of the interface.
  2. Select the "Refractive Index Fit Config" entry and click Download Config.
  3. Choose the most appropriate record from the database list and click OK to load all parameters into the module.

config-options

Save the current settings as a new template​

  1. In the right-side drawer click Upload Config.
  2. In the dialog you can either Overwrite an existing record or Create New (give it a name).
  3. Close the dialog to return to the main screen.

How to set the measurement environment (air refractive index)​

Before importing transmittance/reflectance spectra, the system must know the measurement medium (typically air). If the environment is not defined, boundary conditions will be wrong and fits will fail.

Steps:

  1. Open the right-side drawer.
  2. Select Air Refractive Index and click Download Air Index.
  3. Choose the standard air value (≈ 1.0) and click OK.

How to choose the correct material entry​

The refractive-index fitting module now uses two explicit material import entries:

  1. Import tabulated material
  2. Import model material

Use the correct entry based on what you want to preserve.

When to import a tabulated material​

Choose the tabulated-material entry when:

  1. You want to load wavelength-point n/k data into the refractive-index table.
  2. You want the current layer to calculate directly from the table.
  3. You do not want to rebuild the model parameter UI.

When to import a model material​

Choose the model-material entry when:

  1. You want to load a dispersion model into the layer.
  2. You want to preserve model type and coefficients.
  3. You expect the model parameter editor to rebuild to match the imported model.

How to save the current layer as material​

There are two common save paths:

  1. Save from the refractive-index table editor
  2. Save from the model parameter editor

Save from the refractive-index table editor​

Use this when the current layer should become a tabulated material.

Steps:

  1. Open the refractive-index table editor.
  2. Confirm the wavelength-point data.
  3. Click the upload button.
  4. Save to Coating Material.

Save from the model parameter editor​

Use this when the current layer should become a model material.

Steps:

  1. Open the model parameter editor.
  2. Confirm model type and coefficients.
  3. Click the upload button.
  4. Save to Coating Material.

Practical rule​

If your next step is to continue editing model coefficients, save a model material.

If your next step is to reuse a wavelength table directly, save a tabulated material.
