wedge prism
1Wedge prism — The wedge prism is an optical element typically made of glass ground at slight angles to refract light passing through it from the smaller width side of the prism to the thicker width side of the prism. By refracting the light, the wedge prism… …
2Prism (optics) — For other uses, see Prism (disambiguation). A plastic prism In optics, a prism is a transparent optical element with flat, polished surfaces that refract light. The exact angles between the surfaces depend on the application. The traditional… …
3Wedge (geometry) — In geometry, a wedge is a polyhedral solid defined by two triangles and three trapezoid faces. A wedge has five faces, nine edges, and six vertices. A wedge is a subclass of the prismatoids.A wedge can be considered a degenerate digonal cupola… …
4Prism (geology) — In geology and petrology, a prism is a long, narrow, wedge shaped sedimentary body with a width to thickness ratio greater than 5 to 1 but less than 50 to 1, and a length 1.5 to 3 times its width. These types of sediments are typically formed… …

6wedge — A solid body having the shape of an acute angled triangular prism. [A.S. weeg] dental w. a double inclined plane used for separating the teeth, maintaining the separation once obtained, or holding a matrix in place. * * * (wej) [A.S. wecg] 1. a… …
7Wollaston prism — Prism composed of two wedge shaped prisms with optical axes at right angles. Light emerging has two beams of opposite polarization. Used in differential interference contrast microscopes …
8Nomarski prism — 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 physicist Georges Nomarski. Like the Wollaston prism, the Nomarski prism consists of… …
9Wollaston prism — A Wollaston prism is an optical device, invented by William Hyde Wollaston, that manipulates polarized light. It separates randomly polarized or unpolarized light into two orthogonal, linearly polarized outgoing beams.The Wollaston prism consists …
10quartz wedge — A thin wedge of quartz which provides a means of superposing any required thickness of quartz on a mineral section being viewed under a polarming microscope, the wedge being cut parallel to the optic axis of a prism of quartz crystal. It enables… …
