Flat Lens Zooms Fast
An adaptive liquid crystal (LC) diffractive lens developed at the University of Arizona (U.S.A.) focuses with high efficiency and zooms with millisecond-fast switching times.
An adaptive liquid crystal (LC) diffractive lens developed at the University of Arizona (U.S.A.) focuses with high efficiency and zooms with millisecond-fast switching times. Doctoral student Pouria Valley and colleagues at the University of Arizona (U.S.A.) reported a lens based on a 3-µm-thick layer of nematic liquid crystals (P. Valley et al. “Tunable-focus flat liquid crystal diffractive lens,” Opt. Lett. 35, 336).
