A hand-held viewer for producing a magnified image of an object has a pivotable and swivelable object mount so that an object of interest may be positioned in a plurality of orientations within the viewable area and at different distances from the lens. One presently preferred object mount comprises a yoke with spaced apart arms having slots running along their length for mounting a microscope slide or a photographic slide such as film strips or 35 mm positives. The hand-held viewer desirably includes a detachable background screen assembly to provide a contrasting background against which to view the photographic slide or other object. In a preferred embodiment, the lens may be focused by rotating a thumb-wheel within and extending partially through the body of the viewer.
