Chambers can be dry-filled with pieces that fall inside. They can be filled with a liquid and pieces. Polarizing filters and bifringent materials may be used in the chamber.
Some scopes allow the user to add and remove objects from the chamber.
Chamber scopes are more popular than other types of kaleidoscopes. In a teleidoscope, there is no object chamber containing objects. A clear lens at the end of the scope turns everything it is pointed at into a kaleidoscopic image. In the teleidoscope, the viewer is not limited by the objects in an object chamber. The whole world becomes the kaleidoscope.
