In conclusion, a fully populated master has been manufactured using the DPI® technology. This master contains 29 lens arrays, each one composed of 23 identical aspherical lenses (667 lenses in total). A very sharp natural intersection is created by intersecting lenses, which leads to a 100% fill-factor for each MLA. While DPI® is constrained by certain design limitations (e.g. minimum aperture and minimum sag >10 µm), it has been demonstrated that it is a very effective technology to manufacture (micro) lens array masters beyond any existing solution. By using this technology, fully populated masters can be produced with multiple lenses or lens arrays covering the total surface of a master. By adding any type of alignment marks and fiducials, DPI® can be considered as a complete breakthrough mastering solution for optics replication processes. Read more about the DPI® technology. |
