Multilayer film optics programs

Please send me additions and corrections and suggestions!


  • RP = “reverse problem”. Every program does the “forward problem” (given a material configuration, compute the optical properties), but only the programs marked RP also do the “reverse problem” out-of-the-box (given optical measurement data, guess the materials and thicknesses). Otherwise, you can do the reverse problem only by trial-and-error or by writing your own optimization routine.
