Traditional diffractive optical elements (DOEs) are combined with plastic lenses, but these lenses have issues with yellowing and poor heat resistance.

Traditional diffractive optical elements (DOEs) are combined with plastic lenses, but these lenses have issues with yellowing and poor heat resistance. In contrast, metasurface diffractive optical elements (Metasurface DOEs) do not have these problems and are thinner than traditional DOEs.

The simulated diffraction pattern distribution DOE (Diffractive Optical Element) has been widely applied in facial recognition systems. The image shows a simulation of the distribution on a face after light passes through the DOE.
