Effect of Light-Source Size with 16-mm. Optical Systems
An investigation of two spherical and aspheric condensers, with an f/1.65 projection lens and a test series of high-intensity biplane filament lamps ranging from 200 to 2000 watts, has been conducted to determine the levels of illumination attainable in 16-mm. projection by varying the light-source size.
