Dr William Nicol FRSE FCS (18 April 1770 – 2 September 1851) was a Scottish geologist and physicist who invented the Nicol prism, the first device for obtaining plane-polarized light, in 1828. A Nicol prism was an early type of birefringent polarizer, that consists of a crystal of calcite which has been split and rejoined with Canada balsam.

Light entering the base of the prism is doubly refracted, and when both rays reach the Canada -balsam cement one ray is reflected away from the prism while the other ray continues through the 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 tutorial window.

NICOL PRISM INTRODUCTION • It is a very popular optical device to obtain a plane polarized light.

Nicol Prism When an ordinary ray of light is passed through a calcite crystal, it is broken up into two rays: The ordinary ray which is polarized and has its vibrations perpendicular to the principle section of the crystal and then extra ordinary ray which is polarized and its vibration parallel to the principle section. nicol prism Two pieces of optically clear calcite, cemented by Canada balsam into the shape of a prism. Light entering the base of the prism is doubly refracted, and when both rays reach the Canada -balsam cement one ray is reflected away from the prism while the other ray continues through the prism.
