Quickly calculate the Coefficient of Finesse (F) for optical resonators and Fabry-Perot interferometers. Understand how free spectral range (FSR) and full width at half maximum (FWHM) influence resonator performance. Our easy-to-use tool provides instant results for physicists and engineers.
Formula:
F = FSR / FWHM
Where:
- F = Coefficient of Finesse (dimensionless)
- FSR = Free Spectral Range (in consistent units, e.g., MHz)
- FWHM = Full Width at Half Maximum (in consistent units, e.g., MHz)
Note: FSR and FWHM must be in the same units for a valid calculation.
