<p>An optical characteristic measuring apparatus includes a light source, a detector and a data processing unit. Data processing unit includes a modeling unit, an analyzing unit and a fitting unit. The plurality of film model equations are solved, and prescribed calculation is performed on the assumption that the optical constants included in the plurality of film model equations is identical. Fitting is performed between a waveform obtained by substituting the obtained film thickness and the obtained optical constants of the film into the film model equations and a waveform of the wavelength distribution characteristic obtained by detector, thereby determining that the optical constants included in the plurality of film model equations is identical and that the film thickness and the optical constants obtained by the analyzing unit are correct values.</p> |
