Small-angle X-ray scattering — (SAXS) is a small angle scattering (SAS) technique where the elastic scattering of X rays (wavelength 0.1 ... 0.2 nm) by a sample which has inhomogeneities in the nm range, is recorded at very low angles (typically 0.1 10°). This angular range… … Wikipedia
Collimated light — In the lower picture, the light has been collimated. Collimated light is light whose rays are parallel, and therefore will spread slowly as it propagates. The word is related to collinear and implies light that does not disperse with distance… … Wikipedia

Binoculars — Binocular telescopes, or binoculars (also known as field glasses), are two identical or mirror symmetrical telescopes mounted side by side and aligned to point accurately in the same direction, allowing the viewer to use both eyes (binocular… … Wikipedia
Diffraction topography — (short: topography ) is an X ray imaging technique based on Bragg diffraction. Diffraction topographic images ( topographs ) record the intensity profile of a beam of X rays (or, sometimes, neutrons) diffracted by a crystal. A topograph thus… … Wikipedia
Shearing interferometer — The shearing interferometer is an extremely simple means to observe interference and to use this phenomenon to test the collimation of light beams, especially from laser sources which have a coherence length which is usually a lot longer than the … Wikipedia
Reflecting instrument — Reflecting instruments are those that use mirrors to enhance their ability to make measurements. In particular, the use of mirrors permits one to observe two objects simultaneously while measuring the angular distance between the objects. While… … Wikipedia
