Hi guys! In a recent question, I learned that thin films can go on to measure refractive transmittance by the 'stackrt' method.

Question: 'stackrt' method compared to regular method

1. The difference between the scope of use of the two (which case is applicable)
2. Is there any difference between the measurement results of the two?

stackrt is an analytical solution for thin-film type of devices : https://optics.ansys.com/hc/en-us/articles/360034406254-stackrt-Script-command

You can compare some simple analytical results such as a cavity that many textbooks have formulas that you can use.
