I attach the paper. In fact what I need, is to calculate d, k, n and absorbance of the thin film and finally this values are used to apply the formula no. 4 (see Swanepoel-paper.pdf). And all of this things from that spectra attached (transmission spectra of MgF2 substrate and MgF2 coated)...

The file MgF2 spectrum.txt is that obtained from substrate MgF2 (without thin film), and the second spectrum (Substrate (MgF2) + thinfilm spectrum.txt/MgF2 coated) is obtained from the same substrate with an "unknown" thin film. I attach the "original" file, where you have the T values for the...

Here you go. Note: The both spectra presents an collapse around ~350 and 800 nm, probably due to the change of the parameters of the instrument (lamp and so on - I think).

Someone can help me with an advice? Please.

Homework Statement I need to calculate n, k and d of an "unknown" thin film. I have the transmission spectra of the substrate (MgF2) and substrate + "unknown" thin film See the attachments with: three files - two screenshots of the transmission spectra (see file name for description) -...
