Finesse Value of Cavity Calculator
Calculate the finesse \(F\) of a Fabry–Pérot cavity using the formula:
\( F = \frac{\pi\sqrt{R}}{1-R} \)
where \(R\) is the mirror reflectivity (0 < \(R\) < 1).
* Enter the mirror reflectivity as a decimal (e.g., 0.99).
Step 1: Enter Mirror Reflectivity
Enter a value between 0 and 1 (e.g., 0.99).
