The Twin Elite 2x2x2 Stereo Viewer

Two large focusing multi-element glass achromats and variable interocular are features of this 2 x 2 x 2 (Def.) stereo viewer. The 30mm diameter achromatic lenses (60mm FL) do a great job to cover a full frame stereo image and also correct for chromatic (color) and spherical (shape) aberrations.  A special screw arrangement allows the distance between the lenses to be moved, suiting a wide variety of users with different distances between there eyes (interpupillary distance).  This is our best 2 x 2 viewer.  It will fit all 2 x 2 mounts (including glass mounted Gepe mounts) except very thick Wess mounts.

This viewer is basically identical to the viewer above but does not contain slide holders. It allows the user to view large amounts of slides quickly by reading them from slide pages on a light box. The viewer does not have slide holders which allows for a person to view the slides still in the pages. This will work with Realist stereo slides and 2 x 2 x 2 slides.  This viewer is used extensively for reading Fundus photography results and for previewing 2 x 2 slides before mounting into stereo mounts.  This viewer is a superior replacement to the Donaldson and Larsen Viewer commonly used by ophthalmologist.
