ABSTRACT:
An optical component consists of two or more plane-parallel windows with, respectively, two or more partially reflective surfaces. Each partially reflective surface splits off part of an original beam and produces another redirected beam. The redirected beam undergoes further redirection and attenuation by multiple reflections. Each even-numbered reflection produces a beam deviated from the original's beam direction by an even multiple of the angle between the windows. Thus, for a pair of windows a series of beams are produced that are in a straight line and are equally spaced.
