Webtermined by the reflectivity R of the plates and the attenuation factor A of the medium between them. 6.2 FP Design Aspects 6.2.1 Instrument Finesse The effective finesse of a Fabry–Perot filter may be lowered when the plates are not perfectly aligned: they may be not perfectly parallel, and/or not perfectly flat. Webφ is the phase change on reflection at each surface. A schematic diagram of a FECO interferometer is shown below. Both the sample and the reference surface must have high reflectivity so high finesse multiple beam interference fringes are obtained. If n = 1 and θ = 0° for a bright fringe of order m WebThe finesse, F, for mirrors having identical reflection coefficients, r, is given by. For the case of a confocal interferometer, it can sometimes be convenient to express the finesse as.
