radiopticonProjector Pro*jec"tor, n.
An optical instrument for projecting a picture upon a screen,
as by a magic lantern or by an instrument for projecting (by

the projection is accomplished by means of a combination of
lenses with a prism and a mirror or reflector. Specific
instruments have been called by different names, such as
radiopticon, mirrorscope, balopticon, etc. RadiopticonRadiopticon Ra`di*op"ti*con, n. [Radio- + stereopticon.]
