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. It was the first type of polarizing prism, invented in by William Nicol — of Edinburgh. Unpolarized light ray enters through the left face of the crystal, as shown in the diagram, and is split into two orthogonally polarized, differently directed rays by the birefringence property of the calcite. It passes out the top side of the upper half of the prism with some refraction , as shown. The e -ray merely undergoes a slight refraction, or bending, as it passes through the interface into the lower half of the prism. It finally leaves the prism as a ray of plane-polarized light, undergoing another refraction, as it exits the far right side of the prism.
Nicol prism was designed by William Nicol. 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. The nicol prism is designed in such a way so as to eliminate ordinary ray by total internal reflection. Hence the extra-ordinary ray is transmitted through the prism. Nicol prism is made by taking a calcite crystal whose length is three times its breadth.
Nicol prism is an optical device which is used for producing and analyzing plane polarized light in practice. When a ray of light arrives at an anisotropic crystal, it splits into two rays of polarized light which vibrate in perpendicular planes. One ray obeys the laws of refraction ordinary ray and the other does not extraordinary ray. Additionally, both present different refractive indices their directions of vibration are different. When they leave the crystal, both follow parallel paths even though their planes of vibration continue to be perpendicular.
The definition of Nicol prism in the dictionary is a device composed of two prisms of Iceland spar or calcite cut at specified angles and cemented together with Canada balsam. It is used for producing plane-polarized light. Educalingo cookies are used to personalize ads and get web traffic statistics.

Затем, в отчаянии, он поднял над собой левую руку, чуть не задев по лицу пожилого человека. Камера выхватила исковерканные пальцы Танкадо, на одном из которых, освещенное ярким испанским солнцем, блеснуло золотое кольцо. Танкадо снова протянул руку. Пожилой человек отстранился.
Я могу вам помочь. - Спасибо, не. Мне нужен консьерж. На лице привратника появилась обиженная гримаса, словно Беккер чем-то его оскорбил. - Рог aqui, senor.
