Nicol prism construction

• Construction of Nicol Prism A calcite crystal of length 3 times its breadth is cut along the proper direction. Its principal section is a parallelogram of 71° and 109° angles. The two pieces are ground so that the angles of principal section are changed to 68° and 112°. As shown in the figure. 2017-10-13 2013-10-11 CONSTRUCTION OF NICOL PRISM • Carving out calcite crystal to make its acute angle 71˚to 68˚and its obtuse angle 109˚to 112˚is to satisfy the condition of TIR of o-ray.

As shown in the figure. 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. Explaination nicol prism construction and working in hindi/urdu#rqphysics#MQSir#iitjam#optics Construction: Nicol prism is constructed from a calcite crystal whose length is nearly three times of its width. The end faces of the crystal out down so as to reduce the angles in principal section to a more acute angle of 68° instant of 71°. The most common polarizing prism (illustrated in the tutorial window) was named after William Nicol, who first cleaved and cemented together two crystals of Iceland spar with Canada balsam in 1829.

View All. Presented in Figure 3 is an illustration of the construction of a typical Nicol prism. A crystal of doubly refracting (birefringent) material, usually calcite, is cut along the plane labeled a-b-c-d and the two halves are then cemented together to reproduce the original crystal shape.
