Binocular magnification system

A head-worn binocular steroscopic viewing and illumination system comprising optical means and means for supporting said optical means, said means for supporting being adapted to being worn on a user's head, said optical means comprising first and second viewers spaced by a distance in a range corresponding to varying interocular distances, said viewers being adapted to being positioned adjacent to the eyes of a user, means for projecting light, an aperture common to said first and second viewers and said light projecting means and optically coupled thereto for viewing and projecting light through the aperture, first and second reflective surfaces disposed to provide an optical path between said first viewer and said aperture, third and fourth reflective surfaces disposed to provide an optical path between said second viewer and said aperture, and a fifth reflective surface disposed to provide an optical path between the light projecting means and said aperture, said second, fourth and fifth reflective surfaces being adjacently disposed such that respective optical paths from the second, fourth and fifth reflective surfaces to the common aperture are closely spaced.
