A transparent optical element with at least two polished planes inclined toward each other, from which light reflects or through which it is refracted.
Usually, a wedge-shaped optical element which disperses light passing through it. The name arises from the Greek prisma prismatos, `thing sawn' (well that's what it says in the dictionary anyway...)
A solid with parallel bases, congruent polygons, and sides that are all parallelograms.
In geometry a body with two parallel planes; in optics a body used to reflect light and generate a light spectrum. A prism is made of material that has a greater angle of refraction than its surrounding, which means that beams of light striking the short side of the prism vertically are totally reflected from the inside at the long side and exit at the second short side.

The solids shown are Prisms. The shaded faces are the bases (congruent polygons lying in parallel planes). The other faces are lateral faces and all are parallelograms. Adjacent lateral faces intersect in parallel segments called lateral edges. An altitude of a prism is a segment joining the two base planes and perpendicular to both. The length of an altitude is the height, h, of the prism.

There are many designs of polished, geometric glass shapes designed to “fold the light up” in order to make an instrument more compact. Prisms give the designer many possibilities and can also be used to invert the image and give a stereoscopic effect by enabling the objective lenses to be set wider apart than the eyelenses (in a binocular for example). adiuscope.

This refracts light, or bends it. A light beam enters through one of the prisms' multiple, see-through straight sides, and leaves via another. (Light is sent off in different directions). It is not a reflector because the light changes direction inside the prism, rather than bouncing off the outside surface. (See Reflector).

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 geometrical shape is that of a triangular prism with a triangular base and rectangular sides, and in colloquial use "prism" usually refers to this type.
In geometry, an n-sided prism is a polyhedron made of an n-sided polygonal base, a translated copy, and n faces joining corresponding sides. Thus these joining faces are parallelograms. All cross-sections parallel to the base faces are the same.
