New Projection Lenses for 35-mm Cinema Projectors

A new range of projection lenses for 35-mm cinema projectors is described. General requirements for projection lenses are mentioned. Basic design considerations for the new lens — the Cinelux-Ultra lens — are discussed. Its modulation transfer function (MTF) and other parameters (field curvature, light transmission efficiency, field illumination evenness, distortion, lateral chromatic aberration) are illustrated, and some are compared to earlier Schneider projection lens designs.
