Abstract:

The diapositive printer EN-49 was designed to accomplish all the required functions of several printers into one. The printer accommodates 3 sizes of film format, 2 14 x 2 14 in. 70 mm film, 4.5 x 4.5 in., and 9.0 x 9.0 in. films. By a system of projection lenses it can produce either exact geometry or constant size diapositive prints from any of the specified formats. The diapositive prints are subsequently mounted, stereoscopically viewed and evaluated by use of a Balplex plotter or similar equipment. A unique feature is the simple and foolproof method to align the principal point of the film format to the projection axis. Heretofore fiducial marks were separately aligned with an individual magnification system for each fiducial mark. This method is eliminated by simultaneously projecting the 4 fiducial marks onto a viewing screen mounted in front of the operator. By operating the control knobs the operator can easily define and position the marks to the crossline reticle inscribed on the viewing screen.
