A Nicol prism is a type of polarizer, an optical device made from calcite crystal used to produce and analyse plane polarized light. It is made in such a way that it eliminates one of the rays by total internal reflection, i.e. the ordinary ray is eliminated and only the extraordinary ray is transmitted through the prism. ‘The Nicol prism is made up from two prisms of calcite cemented with Canada balsam.’ ‘The result is a transparent birefringent crystal, known as a Nicol prism, which effective separates polarized light at the interface between the two crystal halves.’ polarizingprismto be invented, in 1828 byWilliam Nicol(17701851) ofEdinburgh. It consists of arhombohedralcrystal ofIceland spar(a variety ofcalcite) that has been cut at an angle of 68 with respect to the crystal axis, cut again diagonally, and then rejoined as shown using, as a glue, a layer of William Nicol Principle When an unpolarized beam enters the noun. A device for producing plane-polarized light, consisting of two pieces of optically clear calcite or Iceland spar cemented together with Canada balsam in the shape of a prism.

An extra-ordinary ray which is polarized and whose vibration is parallel to the principle section of the prism.If by some optical means, one of the One of the most common forms of the Nicol prism is made by taking a calcite crystal whose length is three times its breadth. Types of crystals Crystals like calcite, quartz, ice and tourmaline having only one optic axis are called uniaxial crystals. Answer ANicol Prism is a type of polarizer, an optical device used to produce a polarized beam of light. It is made in such a way that it eliminates one of the rays by total internal reflection, i.e. the ordinary rayis eliminated and only the extraordinary ray is transmitted through the prism. So it works on principle of double refraction. The nicol prism is made of calcite crystal.

Nicol prism is a type of polarizing prism. It is made from calcite crystal which is used to produce and analyze plane polarized light. Nicol prism removes one of the rays by total internal reflection, such as the ordinary ray is removed and the extraordinary ray is transmitted through the prism. Explanation:A Nicol prism is a type of polarizer, an optical device made from calcite crystal used to produce and analyse plane polarized light. It is made in s… Prisms can be made from any material that is transparent to the wavelengths for which they are designed.
