摘要
A multi-magnification, short focal length imaging system is enabled by providing a lens assembly having a plurality of short focal length lens arrays formed within a unitary plastic or glass body. The lens arrays are composed of a plurality of lenslets formed by either a masking/radiation heat treating process when using a photosensitive glass or by plastic injection molding techniques. The lenslets are formed with the appropriate spacing parameters and lens axis tilt orientation to enable projection of a reduced or enlarged image of a document at an image plane. The lens assembly is translated and/or rotated in response to magnification reproduction values selected by an operator so as to place the appropriate lens array into an optical projection path.
