Abstract
A first multiple-lens array designed with positive-power lenses produces multiple bundles of converging light rays, and a second multiple-lens array designed with negative-power lenses produces multiple bundles of collimated light rays at a certain optimal separation between the two multiple-lens arrays. As the axial separation between the two multiple-lens arrays increases, the divergence of the entire beam of light increases.
