Hello everyone. I have some zirconium that is coated with 1nm of Ni. Now, here's the problem: I don't know if the coating is actually 1nm and have to find out. I don't have access to our AFM today, so I can't use that. But I do have light transmission data from the sample. i.e. I know the percentage of light the coating transmits and the percentage reflected. If there any way I can use this to find the thickness of the metal film. Are there data tables somewhere that have information, such as optical transmission vs. thickness or something like that? Any help finding this information would be greatly appreciated.
