Gradient index lens arrays have found wide usage as imaging devices for compact devices by virtue of their relatively short conjugate requirements (60- illumination to be directed against a document scan strip on an overlying document platen with the light reflected along the linear entrance face of the lens array). These requirements are complicated when two or more lens arrays, each having a different magnification value, are formed as an integral imaging assembly. For this configuration, each array may require a separate level of illumination corresponding to the magnification value (e.g. a .6X reduction array may require a greater illumination level than an unity (1X) array.
