The energy throughput of an interferometer is calculated for the case where an unsupported thin film is used as a beamsplitter. The polarization of the beam toward the detector is calculated, and it is shown that by setting the beamsplitter at the Brewster angle rather than the usual 45°, a completely polarized output beam may be expected, and at very little cost in energy. Comparison with experiment is given
