    A Lieberkühn mirror from Emil Busch AG (now Rathenower Optische Werke) circa 1930, digital collection of the Deutsches Museum. [1]A Lieberkühn reflector [2] (also known as Lieberkühn mirror [3] or simply Lieberkühn [2] [4]) is an illumination device for incident light illumination (epi-illumination) in light microscopes.

    Micrasterias furcata imaged in transmitted DIC microscopy Laser-induced optical damage in LiNbO 3 under 150× Nomarski microscopy. Differential interference contrast (DIC) microscopy, also known as Nomarski interference contrast (NIC) or Nomarski microscopy, is an optical microscopy technique used to enhance the contrast in unstained, transparent samples.

  4. Objective (optics) - Wikipedia

    en.wikipedia.org/wiki/Objective_(optics)

    Several objective lenses on a microscope. Objective lenses of binoculars. In optical engineering, an objective is an optical element that gathers light from an object being observed and focuses the light rays from it to produce a real image of the object. Objectives can be a single lens or mirror, or combinations

  5. Interferometry - Wikipedia

    en.wikipedia.org/wiki/Interferometry

    In addition to continuous electromagnetic radiation, Young's experiment has been performed with individual photons, [16] with electrons, [17] [18] and with buckyball molecules large enough to be seen under an electron microscope. [19] Lloyd's mirror generates interference fringes by combining direct light from a source (blue lines) and light ...

    en.wikipedia.org/wiki/Adaptive_optics

    Adaptive thin shell mirror. [5]Adaptive optics was first envisioned by Horace W. Babcock in 1953, [6] [7] and was also considered in science fiction, as in Poul Anderson's novel Tau Zero (1970), but it did not come into common usage until advances in computer technology during the 1990s made the technique practical.

  7. Kirkpatrick–Baez mirror - Wikipedia

    en.wikipedia.org/wiki/Kirkpatrick–Baez_mirror

    A Kirkpatrick–Baez mirror, or simply KB mirror, focuses beams of X-rays by reflecting them at grazing incidence off a curved surface, usually coated with a layer of a heavy metal. It is named after Paul Kirkpatrick and Albert Baez , the inventors of the X-ray microscope .
