    A first-order lens has a focal length of 920 mm (36 + 1 ⁄ 4 in) and stands about 2.59 m (8 ft 6 in) high, and 1.8 m (6 ft) wide. The smallest (sixth) order has a focal length of 150 mm (6 in) and a height of 433 mm (17 + 1 ⁄ 16 in). [58] [59] [60] The largest Fresnel lenses are called hyperradiant (or hyper-radial).

    The Prizm's 1998 redesign coincided with the conversion of all remaining Geo models into Chevrolets, as General Motors made the decision to discontinue the Geo brand entirely after 1997. The most notable change was an all-new 1.8-liter engine known as the 1ZZ-FE , which powered all Corollas and Prizms, making this generation lighter than its ...

  7. 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.

    en.wikipedia.org/wiki/Fresnel_equations

    Fresnel equations. Partial transmission and reflection of a pulse travelling from a low to a high refractive index medium. At near-grazing incidence, media interfaces appear mirror-like especially due to reflection of the s polarization, despite being poor reflectors at normal incidence. Polarized sunglasses block the s polarization, greatly ...
