ABSTRACT:
A beam splitter comprises a splitting device receiving at a first surface a first incident beam in an angle α with respect to the optical axis. A portion of the first incident beam will be reflected at the first surface at the angle α to the optical axis on opposite side with respect to the first incident beam. A second beam will be transmitted through the splitting device. The angle α is selected that the reflected portion is substantially independent of the state of polarization of the first incident beam.
