  3. Specific rotation - Wikipedia

    en.wikipedia.org/wiki/Specific_rotation

    The CRC Handbook of Chemistry and Physics defines specific rotation as: For an optically active substance, defined by [α] θ λ = α/γl, where α is the angle through which plane polarized light is rotated by a solution of mass concentration γ and path length l.

  4. Optical instrument - Wikipedia

    en.wikipedia.org/wiki/Optical_instrument

    An illustration of some of the optical devices available for laboratory work in England in 1858. An optical instrument is a device that processes light waves (or photons), either to enhance an image for viewing or to analyze and determine their characteristic properties.

  5. Dispersion-shifted fiber - Wikipedia

    en.wikipedia.org/wiki/Dispersion-shifted_fiber

    Dispersion-shifted fiber (DSF) is a type of optical fiber made to optimize both low dispersion and low attenuation.. Dispersion Shifted Fiber is a type of single-mode optical fiber with a core-clad index profile tailored to shift the zero-dispersion wavelength from the natural 1300 nm in silica-glass fibers to the minimum-loss window at 1550 nm.

  6. Beam splitter - Wikipedia

    en.wikipedia.org/wiki/Beam_splitter

    Phase shift through a beam splitter with a dielectric coating. Beam splitters are sometimes used to recombine beams of light, as in a Mach–Zehnder interferometer.In this case there are two incoming beams, and potentially two outgoing beams.

  7. Optics - Wikipedia

    en.wikipedia.org/wiki/Optics

    Optics is the branch of physics that studies the behaviour and properties of light, including its interactions with matter and the construction of instruments that use or detect it. [1]

  8. Soxhlet extractor - Wikipedia

    en.wikipedia.org/wiki/Soxhlet_extractor

    A Soxhlet extractor has three main sections: a percolator (boiler and reflux) which circulates the solvent, a thimble (usually made of thick filter paper) which retains the solid to be extracted, and a siphon mechanism, which periodically empties the condensed solvent from the thimble back into the percolator.

  9. Plagioclase - Wikipedia

    en.wikipedia.org/wiki/Plagioclase

    Plagioclase displaying cleavage. (unknown scale) In volcanic rocks, fine-grained plagioclase can display a "microlitic" texture of many small crystals. Plagioclase (/ ˈ p l æ dʒ (i) ə ˌ k l eɪ s, ˈ p l eɪ dʒ-,-ˌ k l eɪ z / PLAJ-(ee)-ə-klayss, PLAYJ-, -⁠klayz) [4] is a series of tectosilicate (framework silicate) minerals within the feldspar group.
