Projected Picture Quality — An Analysis of Lens and Mirror Types

Donald Carignan

Using a theater in which only lenses and arc-lamp mirrors are varied, comparisons of projected image have been made. A high-resolution test film is used in interpreting a visual result in the front, center and rear row of the theater. Various lenses of the same focal length, but of 4-element and 6-element types, have been compared for resolution quality. Also compared are results with silvered and infrared rejecting mirrors to determine the effect on picture quality while using each of the lenses initially tested. The results have been plotted.
