Due to the advantages of the gray scale technology, multi-functional optics can now be created.

The top left image shows an optic that could not be made without the gray scale method. In this picture, a microlens array is shown with a grating superimposed on the lens. If a mixed red/green/blue beam is passed through the optic, the lens function will focus the beam into a spot and the grating function will separate out the three component wavelengths resulting in the output seen in the bottom left image. This capability is especially attractive for projection television and increased efficiency for LCD panels.

The images below are schematics showing our ability to accurately perform a front to back alignment of elements. The picture on the left shows a lens on one side and a diffraction grating on the other while the right picture show lenses on both sides. Using these technologies, front to back alignment accuracies of better than 1 micron can be achieved..
