An optical prism is a transparent optical element with flat, polished surfaces that are designed to refract light. At least one surface must be angled — elements with two parallel surfaces are not prisms. The most familiar type of optical prism is the triangular prism, which has a triangular base and rectangular sides.
Glass bricks provide visual obscuration while admitting light. The modern glass block was developed from pre-existing prism lighting principles in the early 1900s to provide natural light in manufacturing plants. Today glass blocks are used in walls, skylights, and sidewalk lights .
Supernova Era. Supernova Era is a science fiction novel written by the Chinese writer Liu Cixin . This novel portrays a luminous stellar explosion releasing powerful electromagnetic radiation and high-energy particles into the universe as far as the solar system, eight light-years away. Around the world, the chromosomes in human cells are ...
The Sénarmont prism is air spaced, unlike the Wollaston and Rochon prisms. These prisms truly split the beam into two fully polarized beams with perpendicular polarizations. The Nomarski prism is a variant of the Wollaston prism, which is widely used in differential interference contrast microscopy. Thin film polarizers
A compound prism is a set of multiple triangular prism elements placed in contact, and often cemented together to form a solid assembly. The use of multiple elements gives several advantages to an optical designer: [2]
The first fixed lens to be constructed with toroidal prisms was a first-order apparatus designed by the Scottish engineer Alan Stevenson under the guidance of Léonor Fresnel, and fabricated by Isaac Cookson & Co. using French glass; it entered service at the Isle of May, Scotland, on 22 September 1836.

In philosophy of mind, qualia ( / ˈkwɑːliə, ˈkweɪ -/; sg.: quale /- li /) are defined as instances of subjective, conscious experience. The term qualia derives from the Latin neuter plural form ( qualia) of the Latin adjective quālis ( Latin pronunciation: [ˈkʷaːlɪs ...
Abbe prism. The prism consists of a block of glass forming a right prism with 30°–60°–90° triangular faces. When in use, a beam of light enters face AB, is refracted and undergoes total internal reflection from face BC, and is refracted again on exiting face AC.
