Let's set the record staight... A Stereopticon is NOT a Stereoscope. A Stereopticon is a projector, which does not create stereoscopic images. It merely has two lenses that allow smooth transitions from one slide to another. —The preceding unsigned comment was added by 68.74.164.138 ( talk • contribs) .

OED second edition, Merriam-Webster Unabridged for two sources. I'm as surprised as anyone else; as a child I'd always heard the term used to describe what is now called a "stereoscope". 12.103.251.203 22:10, 30 November 2006 (UTC) reply

Any museum folk or collectors out there with information about the care and feeding of the cardboard-backed images? Triviagoddess 16:24, 29 December 2006 (UTC) reply

"Stereopticon" was also the brand name for stereoscopes used by the Keystone Viewing Company of Meadville, PA at the time, to futher add confusion.
