Abstract
An illuminating optical system for use in a microfilm reader/printer or the like for illuminating a film comprises an axially symmetric lens system and an anamorphic lens system. The anamorphic lens system includes a condenser lens opposed to a light source. A microfilm reader/printer having such an illuminating optical system causes the axially symmetric lens system to illuminate the microfilm during a reading operation, and the anamorphic lens system to illuminate the film during a printing operation.
