I think you mean stereoscope, not stereopticon.  Stereopticon is another
word for magic lantern, a very old-fashioned kind of projector, and
notwithstanding the name it has nothing to do with 3-D.

Taylor-Merchant advertises (in Stereo World) just what you need: "two
wedge-shaped lenses, each molded and embodied in 1.5 inch square frame . . .
$7.95 postpaid (USA)."  They make a lot of stereoscopes and related stuff,
so I assume these would be satisfactory, and certainly the price is right.
The address is Taylor-Merchant Corporation, 212 West 35th St., New York, NY
10001.
