Abstract
Three-dimensional and wide-screen projection both require substantially more than the conventional amount of screen light. The super Ventarc has been designed to meet these requirements to such an extent that the screen lumens are only limited by the maximum density of radiant energy the film can take. If this value is set at 0.7 w/sq mm, the ultimate limit for a 35mm projection system will be approximately 50,000 lm, with no film shutter. This level of screen light has been attained at 150 amp.
