The Characteristics and Compatibility of Projection Light Sources

Projection light sources are reviewed historically according to the various types of lamphouses, arc controls, power supplies and optics that have been used. The xenon short-arc lamp has recently become a popular projection light source in American laboratories and studio review rooms. The compatibility of the high-intensity carbon arc and the xenon short-arc lamp sources and the resultant screen light are of importance since there are between them chromatic differences related to the position of each source on the ICI chromaticity curve and the spectral energy within the visible spectrum. Experiments have confirmed that carbon-arc and xenon short-arc projection light sources are compatible within acceptable tolerances.
