ABSTRACT:
A focusing interferometer, wherein the focusing and orientation of the different mirrors of the interferometer have been successfully facilitated by combining the focusing mirror and the collimating mirror to provide a single spherical mirror surface and by reversing the paths of light that start from the beam splitter by assembly of mirrors which are arranged back-to-back to reflect to opposite directions such that their optical axes join, each of the mirrors including three flat mirror surfaces that are perpendicular to one another and are arranged to reflect to the direction of the point where the normals of the mirror surfaces intersect.
