Abstract
Studies relating to the effects of radiant energy upon the film in the projector aperture have become of increasing importance with the use of higher volumes of projected light. A portable device for measuring the radiant energy at the center of the projector aperture is described and its construction outlined. Radiant energy in units of watts per square millimeter can be read directly from a self-contained indicating meter.
