Amici prism. For the reflecting prism, see Amici roof prism. An Amici prism, named for the astronomer Giovanni Battista Amici, is a type of compound dispersive prism used in spectrometers. The Amici prism consists of two triangular prisms in contact, with the first typically being made from a medium-dispersion crown glass, and the second from a ...
Properties. convex, equilateral, zonohedron, parallelohedron. In geometry, a rhombohedron (also called a rhombic hexahedron [1] or, inaccurately, a rhomboid [a]) is a three-dimensional figure with six faces which are rhombi. It is a special case of a parallelepiped where all edges are the same length.
An Amici roof prism. An Amici roof prism, named for its inventor, the Italian astronomer Giovanni Battista Amici, is a type of reflecting prism used to deviate a beam of light by 90° while simultaneously inverting the image. It is commonly used in the eyepieces of telescopes as an image erecting system. It is sometimes called an Amici prism or ...
The octahedral prism consists of two octahedra connected to each other via 8 triangular prisms. The triangular prisms are joined to each other via their square faces. Projections Transparent Schlegel diagram. The octahedron-first orthographic projection of the octahedral prism into 3D space has an octahedral envelope. The two octahedral cells ...
Sennacherib's Annals are the annals of the Assyrian king Sennacherib.They are found inscribed on a number of artifacts, and the final versions were found in three clay prisms inscribed with the same text: the Taylor Prism is in the British Museum, the Oriental Institute Prism in the Oriental Institute of Chicago, and the Jerusalem Prism is in the Israel Museum in Jerusalem.
A Nomarski prism is a modification of the Wollaston prism that is used in differential interference contrast microscopy. It is named after its inventor, Polish and naturalized-French physicist Georges Nomarski. Like the Wollaston prism, the Nomarski prism consists of two birefringent crystal wedges (e.g. quartz or calcite) cemented together at ...
A prism sight or prismatic sight, sometimes also called prism scope or prismatic scope, is a type of telescopic sight which uses a reflective prism for its image-erecting system, instead of the series of relay lenses found in traditional telescopic sights. The use of prisms makes it possible to construct a shorter and lighter sight, or with an ...
D.H. and Others v. the Czech Republic (No. 57325/00) was a case decided by the European Court of Human Rights (ECtHR) concerning discrimination of Romani children in the education system of the Czech Republic.
