Nicol prism was designed by William Nicol. One of the most common forms of the Nicol prism is made by taking a calcite crystal whose length is three times its breadth. It is cut into two halves along the diagonal so that their face angles are 720 and 1080.

Nicol prisms are very expensive and bulky, and have a very limited aperture, which restricts their use at high magnifications. Instead, polarized light is now most commonly produced by absorption of light having a set of specific vibration directions in a dichroic medium.

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. ‘The Nicol prism, which is made entirely of calcite, a doubly refracting mineral, isolates one beam cleanly.’. More example sentences. ‘The two beams, with two different planes of polarization, are then analyzed by another Nicol prism.’.

There is a tablet to his memory in the Wariston Cemetery, in Edinburgh, bearing an inscription drawn up by the late Prof. Tait. Nicol Prism. Home → Nicol Prism He found that when a ray of ordinary light is incident on calcite or quartz crystals, it splits up into two polarized refracted rays.
