Finesse Value of Cavity Calculator

Finesse Value of Cavity Calculator

Calculate the finesse using: $$ \mathcal{F} = \frac{\pi \sqrt{R}}{1 – R} $$

* Enter the mirror reflectivity \(R\) as a fraction (e.g., 0.99).

Step 1: Enter Reflectivity

e.g., 0.99 for 99% reflectivity

Finesse Formula: $$ \mathcal{F} = \frac{\pi \sqrt{R}}{1 – R} $$
