ABSTRACT:
A short focal length lens array has a plurality of lenslets formed within the body of a photosensitive glass. The lenslets have areas which are oriented such that they tilt away from each other from the center out to the array edges. The lens array acts as a reduction or enlargement lens when reproducing objects at an object plane onto an image plane. A one or two row embodiment is disclosed suitable for incremental scanning of a document at image planes. A further full frame lens array is disclosed for providing full frame exposure of a document at various selected magnifications.
