Therefore, achromats will have noticeable advantages over simple lenses. Achromats are far superior to simple lenses for multi-color ("white light") imaging. The two elements composing an achromatic lens (literally, "a lens with no color") are paired together for their ability to correct the color...

We discuss a white-light processing system that produces a dynamic, achromatic Fourier transformation over the visible spectrum. The system includes an achromatic fourier transform lens system and a low-disperion spatial light modulator....
