2) Slot for slides. These were always placed between the illuminant and a focus lens


3) Focus Knob

Lantern design varied according to materials it was made from and its intended use. Lighting systems were interchangeable. Main illuminants were :-


1) Oil burning lamp where a powerful illuminant was not necessary (e.g. entertaining at home)


2) Lime light. Lime produces a brilliant light if heated to a high temperature a combustible gas (often hydrogen) and oxygen could achieve this.


3) Carbon arc


4) Electric filament bulbs were eventually to supersede all other illuminants but were only found on later lanterns
