A system and apparatus for directing a light beam along multiple optical pat hs are disclosed, one embodiment of the apparatus comprising: a base assembly; a first reflective surface set at a first angle to the optical axis of an incident light beam and operable to direct the light beam along a first optical path; and a second reflective surface set at a second angle, different from the first angle, to the optica l axis of the incident light beam and operable to direct the light beam along a second optical path, wherein the first reflective surface and the second reflective surface are operable to move in a linear manner along a common axis, and wherein the base assembly i s operable to linearly reposition the first and second reflective surfaces alo ng the common axis so that the incident light beam is incident on one or the other. The apparatus can further comprise a movement means operably coupled to the base assembly to provide motive force to reposition the first and second reflecti ve surfaces.
