Nicol prism - Wikipedia
A Nicol prism is a type of polarizer. It is an optical device made from calcite crystal used to convert ordinary light into 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.

Nicol Prism - National Museum of American History
A Nicol prism that converts ordinary light into plane polarized light. William Nicol (1770–1851), a geologist and physicist in Edinburgh, invented the form in 1828.

2018年9月10日 · This interactive tutorial explores the generation of orthogonal or mutually perpendicular (ordinary and extraordinary) waves as the result of light transmission through a Nicol prism. A typical Nicol prism is composed of a doubly refracting (birefringent) material, usually calcite, cut along the plane labeled a-b-c-d , as illustrated in the ...

Presented in Figure 5 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.
Nikol Prism - University of California, Berkeley
A Nicol Prism consists of two pieces of calcite glued together. Calcite is birefringent, and thus generates two polarized rays (O-Ray and E-Ray) from unpolarized impinging light. The angle of the glued surfaces causes one of the rays to be internally reflected and lost.

Nicol prism - CAMEO
Invented by William Nicol about 1870, a Nicol prism is composed of two flawless pieces of optical grade calcite (Iceland spar). The pieces are cut and ground to form matching prisms. One prism is placed upside down on the other, then they are cemented together with colorless Canada balsam.
Light through Nicol prism and Nicol analyzer, using arc lamp.
White light from a carbon arc is sent through two Nicol prisms. The first Nicol prism produces plane-polarized light, and the second Nicol prism is used as an analyzer. If the second Nicol prism is rotated through 90 degrees, the projected light will alternate between being bright and being completely extinguished.
