Nicol prism. The Nicol prism is made from a naturally-occurring mineral named Iceland spar. Its crystals have a special double refracting quality, which William Nicol exploited in his invention of 1829, when he cut a rhomb in half, reversed one half, and glued them together with Canada balsam, to form a rhomb similar in appearance to the one he had …

Iceland Spar

The Iceland Spar crystal is a form of Calcite or a crystallized form of calcium carbonate that is completely transparent. Originally brought from Iceland and with the ability to be used for light-polarizing, which separates out light, it is believed to be used by the Vikings in ancient times to find the sun when the sky was overcast with clouds.

What is Nicol Prism? Construction and Working Principle

Fig.4. Working of Nicol Prism . Nicol Prism as a Polariser: In order to produce and analyze the plane polarized light, we arrange two Nicol prisms. When a beam of unpolarized light is incident on the Nicol prism, emergent beam from the prism is obtained as plane polarized, and which has vibrations parallel to the principal section.

Iceland Spar: Optical Calcite | Rock & Gem Magazine

Iceland spar is a transparent variety of calcite that exhibits birefringence, the ability to polarize light and refract it in two slightly different directions. This creates double images when objects are viewed through Iceland spar crystals. Calcite (calcium carbonate, CaCO3) crystallizes in the trigonal system and is slightly denser than quartz.
