  2. Nicol prism - Wikipedia

    en.wikipedia.org/wiki/Nicol_prism

    A Nicol prism is a type of polarizer. It is an optical device made from calcite crystal used to convert ordinary light into plane polarized light . It is made in such a way that it eliminates one of the rays by total internal reflection , i.e. the ordinary ray is eliminated and only the extraordinary ray is transmitted through the prism .

  3. Greenhouse–Geisser correction - Wikipedia

    en.wikipedia.org/wiki/Greenhouse–Geisser...

    Greenhouse–Geisser correction. The Greenhouse–Geisser correction is a statistical method of adjusting for lack of sphericity in a repeated measures ANOVA. The correction functions as both an estimate of epsilon (sphericity) and a correction for lack of sphericity. The correction was proposed by Samuel Greenhouse and Seymour Geisser in 1959.

    Laser modules (bottom to top: 405, 445, 520, 532, 635, and 660 nm) Laser science or laser physics is a branch of optics that describes the theory and practice of lasers. [citation needed] Laser science is principally concerned with quantum electronics, laser construction, optical cavity design, the physics of producing a population inversion in ...

  5. Dye laser - Wikipedia

    en.wikipedia.org/wiki/Dye_laser

    A dye laser uses a gain medium consisting of an organic dye, which is a carbon-based, soluble stain that is often fluorescent, such as the dye in a highlighter pen. The dye is mixed with a compatible solvent, allowing the molecules to diffuse evenly throughout the liquid.

    Small incision lenticule extraction. ReLEx Small incision lenticule extraction ( SMILE ), second generation of ReLEx Femtosecond lenticule extraction ( FLEx ), is a form of laser based refractive eye surgery developed by Carl Zeiss Meditec used to correct myopia, and cure astigmatism. Although similar to LASIK laser surgery, the intrastromal ...

  7. Laser blended vision - Wikipedia

    en.wikipedia.org/wiki/Laser_blended_vision

    Laser blended vision is a laser eye treatment which is used to treat presbyopia (ageing eyes; [1] progressive loss of the ability to focus on nearby objects) or other age-related eye conditions. [1] It can be used to help people that simply need reading glasses, and also those who have started to need bifocal or varifocal spectacle correction ...

  8. Wedge prism - Wikipedia

    en.wikipedia.org/wiki/Wedge_prism

    Wedge prism. The wedge prism is a prism with a shallow angle between its input and output surfaces. This angle is usually 3 degrees or less. Refraction at the surfaces causes the prism to deflect light by a fixed angle. When viewing a scene through such a prism, objects will appear to be offset by an amount that varies with their distance from ...
