Abstract: An interferometer has a first reflective surface having a nominal orientation; a second reflective surface having a nominal orientation orthogonal to the nominal orientation of the first reflective surface; a retroreflector facing the first reflective surface; a double polarizing beam splitter (DPBS) between the first reflective surface and the retroreflector; and a respective quarter-wave plate between the DPBS and each of the reflective surfaces. The DPBS has first and second beam-splitting surfaces each having a nominal orientation with respect to the first reflective surface. At least part of at least one of the first reflective surface, the second reflective surface and the beam-splitting surfaces is effectively tilted relative to the respective nominal orientation of such surface, and constitutes a respective tilted surface.
