Carbon-Arc Image Furnaces

M. R. Null, W. W. Lozier

Carbon-are motion-picture projection lamps are useful in the production of extremely high flux densities of radiant energy. The application of these to carbon-arc image furnaces has been described. They are also valuable in many studies requiring high concentrations of radiant energy in any portion of the spectrum from the arc. Comparisons are made of the distribution of irradiance and illuminance across the image with three different types of optical systems. The spectral distribution of irradiance at the center of the image is also given.
