LINNEBACH PROJECTOR
Optically simple lensless system for projecting a shape from a gel or glass slide etc. onto a set or cloth.

The projector was developed in Germany by Adolphe Linnebach (1876-1963) in 1916 at the Court Theater, Dresden. In order to get a sharp image, the lamp filament should be as small and as bright as possible, with adjustment to move it towards and away from the slide. A high intensity low voltage lamp is often used for this purpose.
