Abstract
To meet the growing demand for improved high-aperture 16-mm projection lenses, the Eastman Kodak Co. has announced a new series of f/1.5 lenses primarily intended for professional projectors. The lens is fundamentally of the Petzval type with field flattener. The resolving power, contrast and back focus clearance are substantially greater than in present designs. The paper includes a historical outline of the development of lenses of this type, showing the progressive improvements in aberration correction that have been attained in recent years.
