\Ste`re*op"ti*con\, n. [NL. See {Stereo-}, and {Optic}.] An instrument, consisting essentially of a magic lantern in which photographic pictures are used, by which the image of a landscape, or any object, may be thrown upon a screen in such a manner as to seem to stand out in relief, so as to form a striking and accurate representation of the object itself; also, a pair of magic lanterns for producing the effect of dissolving views.
