  • an outer housing having front and rear walls and a viewing hole through said front wall;

    support means for said object located within said housing;

    illuminating means within said housing, said illumination means providing rays of light to reflect off the object; and

    first and second concave mirrors positioned within said outer housing, said second concave mirror positioned to focus said rays of light to a virtual image formed by reflection from said second concave mirror, said first concave mirror positioned to reflect said rays reflected from said second concave mirror and to focus to a real image of said object said rays reflected from said second concave mirror, said concave mirrors being arranged to form an acute angle with respect to one another, and further being arranged such that the optical axes of each of said concave mirrors intersects a vertical plane passing through the center of said viewing hole, wherein said real image extends at least in part outside said housing and is magnified with respect to said object.
