Table 2
Phase retardation of a pair commercial interferential mirrors, the † symbol designating the same mirrors with a lower finesse, see text. R and F are the mean and standard deviation of respectively the reflectivity and finesse obtained by averaging photon lifetime measurements during the rotation of the mirror, and δ is the phase retardation per reflection. Uncertainties are given with a coverage factor k = 1.
