The Color of Light on the Projection Screen

M. R. Null, W. W. Lozier, D. B. Joy

Spectral energy distribution measurements of the light at the center of the projection screen have been made for a number of arc lamp and carbon combinations employed in motion picture projection. ICI color-coördinates and color-temperatures have been calculated and show that the various high-intensity combinations give chromaticities and color-temperatures which agree closely among themselves. The spectral-energy distribution data of both low and high-intensity lamps and carbons show marked similarity to black-body curves.
