Broadband imaging with one planar diffractive lens. [PDF]
Sci Rep, 2018 We demonstrate imaging over the visible band using a single planar diffractive lens. This is enabled via multi-level diffractive optics that is designed to focus over a broad wavelength range, which we refer to as an achromatic diffractive lens (ADL). We
