1. An optical scanning system selectively operative as a camera and a microscope, said scanning system comprising:

  • a folded optical path having a set of radiation converging and reflecting elements;

    a camera field of view;

    a microscope field of view;

    a radiation detector;

    selectable means for selecting first and second routings with significantly different optical properties for radiation through said set of elements of said optical path whereby said elements are operative in a different sequence in said first and second routings;

    said first routing providing for radiation to traverse said folded optical path from said camera field of view to said radiation detector and providing for placement of said one or more converging elements relatively closer to said radiation detector;

    said second routing providing for radiation to traverse said folded optical path from said microscope field of view to said radiation detector and providing for placement of said one or more converging elements in said second radiation routing relatively closer to said microscope field of view; and

    means for providing scanning by said folded optical path of radiation incident on said radiation detector from said fields of view.
