Samsung patents stacked-layer metalens for thinner cameras

Samsung describes a metalens, a flat lens made of tiny structures rather than curved glass, that uses stacked layers to focus light. The patent details how these layers are arranged with decreasing sizes from the center to the edge to control how light passes through.

Why it mattersThis design could help manufacturers create thinner camera modules for phones and other devices by replacing traditional bulky glass lenses with flat, layered structures.

In the filing’s own words

A metalens includes a substrate, and a metasurface provided on the substrate and including a plurality of metaatoms, where at least one of the plurality of metaatoms may include a plurality of layers.

What exactly they claim (claim 1)

1. A metalens comprising: a substrate; and a metasurface provided on the substrate and comprising a plurality of metaatoms, wherein at least one of the plurality of metaatoms comprises a plurality of layers, and wherein the plurality of layers comprise a first layer, a second layer and a third layer sequentially stacked in a first direction from the substrate, each having, in a second direction intersecting the first direction, a different length between a center and an edge, and wherein the length between the center and the edge of the first layer is greater than the length between the center and the edge of the second layer, and the length between the center and the edge of the second layer is greater than the length between the center and the edge of the third layer.
