Neon Crater Lamp for Mechanical Television Set

Neon-Kraterlampe für mechanisches Fernsehgerät

A crater lamp is a high intensity neon lamp with a very small spot size; its brightness is proportional to the signal current sent through the lamp. It provides, therefore, a bright point source of light which is modulated behind the spinning Nipkow disc of a mechanical television to assemble the picture. This allows a somewhat larger and brighter picture than is possible with flat plate tubes like the DeForest 601 Vis-Ion Kino Lamp.
