  2. Prism compressor - Wikipedia

    en.wikipedia.org/wiki/Prism_compressor

    However, high-order dispersion will be introduced by the prism compressor itself, as well as other optical elements. It can be corrected with careful measurement of the ultrashort pulse and compensate the phase distortion. MIIPS is one of the pulse shaping techniques which can measure and compensate high-order dispersion automatically.

  3. Pentagrammic prism - Wikipedia

    en.wikipedia.org/wiki/Pentagrammic_prism

    It is a special case of a right prism with a pentagram as base, which in general has rectangular non-base faces. Topologically it is the same as a convex pentagonal prism . It is the 78th model in the list of uniform polyhedra , as the first representative of uniform star prisms , along with the pentagrammic antiprism , which is the 79th model.

  5. Surface plasmon resonance - Wikipedia

    en.wikipedia.org/wiki/Surface_plasmon_resonance

    Surface plasmon resonance (SPR) is a phenomenon that occurs where electrons in a thin metal sheet become excited by light that is directed to the sheet with a particular angle of incidence, and then travel parallel to the sheet. Assuming a constant light source wavelength and that the metal sheet is thin, the angle of incidence that triggers ...

  6. Formula editor - Wikipedia

    en.wikipedia.org/wiki/Formula_editor

    A formula editor is a computer program that is used to typeset mathematical formulas and mathematical expressions. Formula editors typically serve two purposes: They allow word processing and publication of technical content either for print publication, or to generate raster images for web pages or screen presentations.

  7. Schmidt–Pechan prism - Wikipedia

    en.wikipedia.org/wiki/Schmidt–Pechan_prism

    The lower prism uses one total internal reflection, followed by a second reflection on the bottom surface to direct the beam into the second Schmidt prism. This second reflection in the lower prism happens at less than the critical angle, therefore the Schmidt–Pechan prism requires a reflective coating for this surface to be usable in ...

  8. End correction - Wikipedia

    en.wikipedia.org/wiki/End_correction

    Hence an end correction is sometimes required to appropriately study its properties. The end correction depends on the radius of the object. An acoustic pipe, such as an organ pipe, marimba, or flute resonates at a specific pitch or frequency. Longer pipes resonate at lower frequencies, producing lower-pitched sounds.

  9. Pellin–Broca prism - Wikipedia

    en.wikipedia.org/wiki/Pellin–Broca_prism

    A Pellin–Broca prism is a type of constant-deviation dispersive prism similar to an Abbe prism. The prism is named for its inventors, the French instrument maker Ph. Pellin and professor of physiological optics André Broca .
