Zirconium Concentrated-Arc Lamps
Zirkonium konzentrierte Bogenlampen
The concentrated-arc lamp was developed by the Western Union Telegraph Company starting in 1943.
Nearly 6,000 lamps of various types were supplied to the Armed Services and to other government agencies and contractors
for wartime use. The principal application of the lamps was their use in the early models of an infrared voice and code
communication system.
Concentrated-arc lamps were also used by the Army in a narrow-beam, battery-operated aural signal unit
for code and voice communication; by the Navy in a hand-held equipment of medium beam width for voice communication between
airplanes, or between airplanes and ground stations; by various Armed Service agencies and contractors in bore-sighting
equipment; and by the Office of Strategic Services in equipment for projecting aerial photographs from the same angle at
which the exposures were made.
After the war, these lamps have been successfully used for a number of applications requiring a
high-intensity, concentrated radiation source, for example microscopy and photographic enlargers.
However, zirconia lamps were short lived and soon superseded by mercury short arc lamps.
