R-Fit™ is designed to analyse data recorded at any wavelength or at any angle of incidence, with a large variety of growth substances and can cope with any number of individual layers.

For each layer in a multi-layered structure, R-Fit™ provides results for the:

  • Complex refractive index
  • Growth rate
  • Individual layer thickness
  • RMS roughness at the end of the layer

R-Fit™ is perfect for:

  • Analysing all stages in the growth of multi-stage structures such as GaN on sapphire
  • Quantifying changes in the refractive index during film growth
  • Identifying if there are changes in the growth rate during layer deposition e.g. CdS on glass
  • Predicting an interferogram before growth starts
  • R-Fit™ turns you into an expert in complex interferometry, providing you and your organisation with meaningful information in minutes.
