Demonstrations for Models Made with RP Coating
Various example cases illustrate what you can do with the thin-film design software RP Coating:
- anti-reflection coatings (with Monte-Carlo optimization)
- short-pass and long-pass filters (analytical design, optional numerical optimization)
- Bragg mirror (comprehensive analysis of a design)
- dichroic mirror (design with numerical optimization)
- air-spaced etalon (including an analysis of the transmission of ultrashort pulses)
- etalon with thermal effects (exhibits bistable behavior)
- thin-film plate polarizer (with numerical optimization)
- polarizing cube (with numerical optimization)
- Gires–Tournois interferometer (including an analysis of the transmission of ultrashort pulses)
- rugate filter (with parameterized generation of a complex structure)
- fitting of layer data to measured reflectivity spectra
- tightly focused beam (taking into account the beam divergence)

The input scripts for these and some other demo cases are delivered together with the software. For an easy start in a new project, you can simply copy the demo file of a case which is closest to the case of interest and modify it according to your needs.
