Gradient index lens arrays have been used as imaging arrays in photocopiers. The arrays are typically formed by combining two rows of gradient index fibers of appropriate length into a bundled array. Arrays having widths of 12 inches are the norm but are not suitable for applications which copy wider original documents such as blueprints. One method of forming wider arrays is to combine several standard 12 inch arrays. This can be accomplished, in one example shown in the Figure, by joining together three 12 inch arrays. Outer arrays 10 and 12 are cut at specific angles to middle array 14. Array 14 is joined to the outer arrays 14 so that the fiber rows 14a, 14b are slightly offset from fiber rows 10a, 10b and 12a, 12B.
