ABSTRACT:
A compact optical bench type unit for making selected color-component records of color transparencies for use in color printing comprises a light source with a rotary filter disc for directing a beam of selectively colored light through a light condenser which converges the beam through a color diapositive to be reproduced and into the objective of a camera. The condenser, possibly formed of Fresnel lenses, is of large dimensions to accommodate large diapositives, and the camera objective has a relatively short focal length. Chromatic aberration of the condenser is corrected by moving the light source in correspondence with rotation of the filter disc, or by selectively inserting correcting lenses in the beam.
