Folding Stereoscopes

Folding Stereo Scope

For viewing in 3-D when used in conjunction with stereo pictures or aerial photos. Made of high impact, crystal-clear plastic with a 2.2x magnification, 4.7" focal length, adjustable inter-pupillary distance, and folding legs for compact storage. Use with any of the stereo books or stereo photo sets or for an aid during mounting of stereo pairs.

The design of this stereoscope is based on the pocket stereoscopes used by the military for air photo interpretation. They’re made entirely of crystal-clear plastic and are held at the correct focus by wire legs that fold up when the stereoscope isn’t being used. The 4¾-inch focal length of the lenses magnifies the images about 2.2 times. A nice feature of these stereoscopes is that the interocular distance can be adjusted from 60 to 70 mm to precisely suit each individual user.

This stereoscope has two element achromatic lenses (corrects for chromatic and sperical aberrations)  and an adjustable interpupillary range 50 mm to 75 mm.  This scope was designed for use by the military for analysis of aerial photographs but we have found that it works very well for viewing stereo slides when mounting for proper adjustment, viewing electron microscope pairs, viewing medium format stereo slides on a light box and for viewing stereo prints up to the size of Holmes Stereo cards (7.5inches for the pair) without a lightbox.  

To view a stereocard with this viewer it should be set at close to the maximum interpupillary distance (~75mm). It will then take advantage of the prismatic effect to allow viewing of a large image. When viewing stereo slides for the purpose of mounting the viewer should be set to your normal interpupillary distance (around 63-68mm).  It is rugged made of an Aluminum frame with folding legs. Padded case. It meets DOD Spec. MIL-S-3629D.
