Projection Performance of Theatrical Motion-Picture Films Using Xenon Short-Arc Lamps

Paul Preo

Excessive incident radiant energy can cause projection problems and film damage. This article reports the results of studies using the new xenon-arc lamps, which are capable of producing even higher levels of radiant energy than are carbon-arc lamps, when manufacturers' recommendations are not followed. Prolonged projection under these high-flux densities can lead to permanent color print scorching or emulsion layer separation. Black-and-white films will blister at even lower flux-density levels. The article describes the effect of xenon-arc lamp maladjustment on the radiant-flux densities and the projection problems and film damage that can result.
