  2. Fresnel rhomb - Wikipedia

    en.wikipedia.org/wiki/Fresnel_rhomb

    A Fresnel rhomb is an optical prism that introduces a 90° phase difference between two perpendicular components of polarization, by means of two total internal reflections. If the incident beam is linearly polarized at 45° to the plane of incidence and reflection, the emerging beam is circularly polarized, and vice versa.

  3. Fresnel lens - Wikipedia

    en.wikipedia.org/wiki/Fresnel_lens

    A Fresnel lens ( / ˈfreɪnɛl, - nəl / FRAY-nel, -⁠nəl; / ˈfrɛnɛl, - əl / FREN-el, -⁠əl; or / freɪˈnɛl / fray-NEL [1]) is a type of composite compact lens which reduces the amount of material required compared to a conventional lens by dividing the lens into a set of concentric annular sections.

  4. Compact linear Fresnel reflector - Wikipedia

    en.wikipedia.org/wiki/Compact_Linear_Fresnel...

    A compact linear Fresnel reflector ( CLFR) – also referred to as a concentrating linear Fresnel reflector – is a specific type of linear Fresnel reflector ( LFR) technology. They are named for their similarity to a Fresnel lens, in which many small, thin lens fragments are combined to simulate a much thicker simple lens.

  5. Augustin-Jean Fresnel - Wikipedia

    en.wikipedia.org/wiki/Augustin-Jean_Fresnel

    Augustin-Jean Fresnel (also called Augustin Jean or simply Augustin), born in Broglie, Normandy, on 10 May 1788, was the second of four sons of the architect Jacques Fresnel [11] and his wife Augustine, née Mérimée. [12] The family moved twice—in 1789/90 to Cherbourg, [13] and in 1794 [14] to Jacques's home town of Mathieu, where Madame ...

    However, I've learned that although the thought of maxing out a 401 (k) sounds appealing, the unfortunate truth is that it's a bit of an overrated goal for people who don't have the means to max ...

  7. Fresnel equations - Wikipedia

    en.wikipedia.org/wiki/Fresnel_equations

    The Fresnel equations give the ratio of the reflected wave's electric field to the incident wave's electric field, and the ratio of the transmitted wave's electric field to the incident wave's electric field, for each of two components of polarization. (The magnetic fields can also be related using similar coefficients.)

  8. Zone plate - Wikipedia

    en.wikipedia.org/wiki/Zone_plate

    A zone plate is a device used to focus light or other things exhibiting wave character. [1] Unlike lenses or curved mirrors, zone plates use diffraction instead of refraction or reflection. Based on analysis by French physicist Augustin-Jean Fresnel, they are sometimes called Fresnel zone plates in his honor.
