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.

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.
