TELEIDOSCOPE There is no endpiece containing color, only a clear lens that turns everything it is pointed toward into a kaleidoscopic image. The teleidoscope is the purest form of a kaleidoscope, because the viewer is not limited by the objects in an endpiece. Rather, the whole world becomes his kaleidoscope. It's been said that the ultimate value of the teleidoscope is the potential each viewer has to see the artistic value in his own environment.
Most teleidoscopes contain a simple equilateral three-mirror arrangement. However, every mirror system used in a standard kaleidoscope can also be used in a teleidoscope
CELLSCOPE The endpiece is an enclosed case containing colored objects (also called object case or chamber). Cells can be: dry-filled with tumbling pieces (front or side-lit); liquid-filled with floating pieces (front or side-lit); polarized light material and filters; empty to allow personal choice of items; tubes-elongated clear case with floating items in liquid.

There are more cell scopes than any other type. The many moving pieces provide the most varied and non-repetitive imagery. There is also more variety in the cell itself. clear, frosted, or etched; recessed, flush, or protruding; black backdrop, side-lit; and liquid-filled. Increasingly popular are the cells that can be opened to include favorite objects.
