Abstract

212,559. Optische Anstalt C. P. Goerz Akt.-Ges. March 8, 1923, [Convention date]. Drawings to Specification. Lenses.-An optical attachment for rendering the image of a' photographic lens diffused is made so as to slightly reduce the angle of the image in order to remove the focusing difference for objects at a finite distance. The device may be made of homogeneous glass or of glasses having the same or substantially the same refractive index and is made with a forwardly concave curvature. Optical data are given.
