Source: Nature Understanding Flat Optics Flat optics refer to optical elements that are thin and lack curved surfaces like traditional lenses. These elements include optical windows, filter plates, thin-film polarizers, and diffractive optical elements. Flat metalenses and photonic metasurfaces are examples of flat optics that contain nanoscale structures to achieve unique optical properties. Advantages of […]

These functions describe the spectral sensitivity of the human eye, providing a framework for how different lighting conditions affect our vision. The International Commission on Illumination (CIE) has standardized
