| Patent Number: |

| Title: |
Zoomable Beamspreader For Non-Imaging Illumination Applications |
| 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.
