Fitting

fit-main

1. Thickness​

  • Start thickness
  • End thickness
  • Thickness interval

2. Initial Values​

  • n
  • k

3. Stop Criteria​

Defines conditions to stop a fitting run.

3.1 Objective Function​

Stop when the objective-function value is below the configured threshold.

3.2 Optimization Cycles​

Stop when the configured optimization-cycle count is reached.

4. Algorithm​

Currently only Filmstar built-in algorithms are supported.

5. Spectrum Target​

Photometric fitting uses film stack, layer thickness and refractive index to match spectrum targets, so a valid spectrum target is required.

See Spectrum Target.

Client UI Notes​

  • The OSC client application includes interactive validation and diagnostic panels. Diagnostic and validation text areas are selectable across multiple lines and the client provides a "copy" action to copy the full diagnostic or validation text to the clipboard.
  • When preparing user documentation or screenshots, use the client's screenshot automation or capture the active window; example developer scripts and guidance are available in the repository's developer docs (osc_dev_doc/UI_TESTING_AND_SCREENSHOT_AUTOMATION.md).
