Low price Achromatic Doublet Lenses on all-dielectric metasurface-based achromatic lenses
An achromatic lens based on an all-dielectric metasurface, comprising: a substrate and a double-layer metasurface on the substrate; the substrate is covered with a layer of low dielectric constant material, and a nanostructure unit is distributed on the surface of the substrate and filled in the low dielectric constant. in the dielectric constant material layer.

Achromatic lenses can not only eliminate chromatic aberration, but also eliminate spherical aberration by appropriately changing the radius of curvature of each surface. If the two glasses that make up the doublet can be chosen arbitrarily, it can also eliminate coma at the same time.
