Assume an air-filled Fabry-Perot interferometer made from two similar, parallel mirrors. For a wavelength of 610nm, the fraction of transmitted light to incident light is 0.0154. The distance of separation is ℓ = 2.60μm. What is (a) the finesse, F, and (b) the reflectance of the mirrors, R, when assuming only reflective contributions to the etalon's finesse?
