摘要：A phase-adjusting element configured to provide substantially liquid-invariantextended depth of field for an associated optical lens. One example of a lensincorporating the phase-adjusting element includes the lens having surface with a

modulated relief defining a plurality of regions including a first region and a secondregion, the first region having a depth relative to the second region, and a plurality ofnanostructures formed in the first region. The depth of the first region and a spacingbetween adjacent nanostructures of the plurality of nanostructures is selected toprovide a selected average index of refraction of the first region, and the spacingbetween adjacent nanostructures of the plurality of nanostructures is sufficiently smallthat the first region does not substantially diffract visible light.
