Webaperture of the device. Typically the mirror spacing must be uniform to λ/50 or better for the total finesse to be dominated by the reflectivity of the mirrors for liquid crystal filled Fabry-Perots. The finesse is also the ration of free spectral range to the bandpass full width at half maximum. For an appropriate choice of liquid crystal, a ... WebJul 1, 2011 · Grating reflectivity at the Bragg wavelength for TE polarization as a function of grating length. The blue dots represent the reflectivity as determined from the measured finesse and Eq. (8), while the dashed line is the predicted reflectivity according to the approximation in Eq. (2). Download : Download high-res image (330KB) WebA high finesse is desirable in spectroscopy and spectrum analysis as the Etalon can possess both a large Free Spectral Range and a small resonator bandwidth allowing for a high spectral resolution.
