  2. X-ray optics - Wikipedia

    en.wikipedia.org/wiki/X-ray_optics

    X-ray optics is the branch of optics dealing with X-rays, rather than visible light.It deals with focusing and other ways of manipulating the X-ray beams for research techniques such as X-ray diffraction, X-ray crystallography, X-ray fluorescence, small-angle X-ray scattering, X-ray microscopy, X-ray phase-contrast imaging, and X-ray astronomy.

  3. Minecraft modding - Wikipedia

    en.wikipedia.org/wiki/Minecraft_modding

    A Minecraft mod is a mod that changes aspects of the sandbox game Minecraft. Minecraft mods can add additional content to the game, make tweaks to specific features, and optimize performance. Thousands of mods for the game have been created, with some mods even generating an income for their authors.

  4. C79 optical sight - Wikipedia

    en.wikipedia.org/wiki/C79_optical_sight

    The M145 Machine Gun Optic is a variant of the C79 that was developed for the U.S. Army and is commonly mounted on M240 and M249 machine guns. The M145 is unusual when compared with other optical sights in use with the United States military in that ballistic compensation is in the mount, rather than in the reticle.

  5. X-ray microscope - Wikipedia

    en.wikipedia.org/wiki/X-ray_microscope

    The ALS is also home to the world's first soft x-ray microscope designed for biological and biomedical research. This new instrument, XM-2 was designed and built by scientists from the National Center for X-ray Tomography. XM-2 is capable of producing 3-dimensional tomograms of cells.

  6. Telescopic sight - Wikipedia

    en.wikipedia.org/wiki/Telescopic_sight

    The scope base is the attachment interface on the rifle's receiver, onto which the scope rings or scope mount are fixed. Early telescopic sights almost all have the rings that are fastened directly into tapped screw holes on the receiver, hence having no additional scope base other than the receiver top itself.

  7. X-ray reflectivity - Wikipedia

    en.wikipedia.org/wiki/X-ray_reflectivity

    X-ray reflectivity (sometimes known as X-ray specular reflectivity, X-ray reflectometry, or XRR) is a surface-sensitive analytical technique used in chemistry, physics, and materials science to characterize surfaces, thin films and multilayers.

  8. Project Excalibur - Wikipedia

    en.wikipedia.org/wiki/Project_Excalibur

    Comparing a ruby laser that operates at 694.3 nm to a hypothetical soft X-ray laser that might operate at 1 nm, this means the X-ray transition is 694 3, or a little over 334 million times less likely. To provide the same total output energy, one needs a similar increase in input energy.

  9. Shoe-fitting fluoroscope - Wikipedia

    en.wikipedia.org/wiki/Shoe-fitting_fluoroscope

    A shoe-fitting fluoroscope was a metal construction covered in finished wood, approximately 4 feet (1.2 m) high in the shape of short column, with a ledge with an opening through which the standing customer (adult or child) would put their feet and look through a viewing porthole at the top of the fluoroscope down at the X-ray view of the feet ...
