Optical waves can pass through the optical cavity only when they are in resonance with it. It is named after Charles Fabry and Alfred Perot, who developed the instrument in 1899. Etalon is from the French étalon, meaning "measuring gauge" or "standard". WebThe finesse is related to the Q factor: the latter is the finesse times the resonance frequency divided by the free spectral range.Essentially, while the finesse relates the resonance bandwidth to the free spectral range, the Q factor relates it to the average optical frequency..
