New Lens Provides Nanometer-Scale Resolution

Facebook X LinkedIn Email
HAMBURG, Germany, March 27, 2018 — A multilayer pair of materials, tungsten carbide and silicon carbide, was used to prepare high-efficiency, high-numerical aperture (NA) multilayer Laue lenses (MLLs). In a series of studies, Saša Bajt of Deutsches Elektronen-Synchroton (DESY) and co-workers used a pair of MLLs to achieve a 2D focus of 8.4 × 6.8 nm at a photon energy of 16.3 keV. They demonstrated scanning-based imaging of samples with a resolution below 10 nm. The high NA of the lenses also allowed projection holographic imaging with strong phase contrast over a large range of magnifications. ...Read full article

    nanopositioning
    Nanopositioning refers to the precise and controlled movement or manipulation of objects or components at the nanometer scale. This technology enables the positioning of objects with extremely high accuracy and resolution, typically in the range of nanometers or even sub-nanometer levels. Nanopositioning systems are employed in various scientific, industrial, and research applications where ultra-precise positioning is required. Key features and aspects of nanopositioning include: Small...
    nano
    An SI prefix meaning one billionth (10-9). Nano can also be used to indicate the study of atoms, molecules and other structures and particles on the nanometer scale. Nano-optics (also referred to as nanophotonics), for example, is the study of how light and light-matter interactions behave on the nanometer scale. See nanophotonics.
    optical materials
    Materials that, by virtue of their optical characteristics (i.e. refractive index, dispersion, etc.), are used in optical elements. See crystal; glass; plastic lens.
