A 50-mm, f/1.4, six-element lens based on a new configuration has been developed for a 16-mm cinematographic projector. In this design, Indian-made Central Glass and Ceramic Research Institute (CGCRI) glasses are used. To compare the performance of this system, a separated six-element Petzval configuration based on U.S. Patent No. 2,541,484, Ex. 1, is designed under similar conditions of optimization using CGCRI glasses. The performance of both designs is compared using transverse aberration curves, energy distribution curves, and geometrical modulation transfer function (MTF) curves. These criteria for image evaluation indicate that the proposed new configuration gives better performance than the 16-mm motion picture projection lens based on the Petzval configuration. The same conclusion is also drawn from a comparison of resolving power at different field angles for both the systems.
