Polarizing microscope operating principle Depiction of internal organs of a midge larva via birefringence and polarized light microscopy. Polarized light microscopy can mean any of a number of optical microscopy techniques involving polarized light. Simple techniques include illumination of the sample with polarized light.
William Nicol invented a prism for polarization in 1829, which was an indispensable part of the polarizing microscope for over 100 years. Later the Nicol prisms were replaced by cheaper polarizing filters. The first complete polarizing microscope was built by Giovanni Battista Amici in 1830.

1625: Giovanni Faber of Bamberg (1574–1629) of the Linceans, after seeing Galileo's occhiolino, coins the word microscope by analogy with telescope. 1655: In an investigation by Willem Boreel, Dutch spectacle-maker Johannes Zachariassen claims his father, Zacharias Janssen, invented the compound microscope in 1590. Zachariassen's claimed ...
Antonie van Leeuwenhoek (1632–1723). The field of microscopy (optical microscopy) dates back to at least the 17th-century.Earlier microscopes, single lens magnifying glasses with limited magnification, date at least as far back as the wide spread use of lenses in eyeglasses in the 13th century [2] but more advanced compound microscopes first appeared in Europe around 1620 [3] [4] The ...
It was the first type of polarizing prism, invented in 1828 by William Nicol (1770–1851) of Edinburgh. Mechanism

Sir David Brewster KH PRSE FRS FSA Scot FSSA MICE (11 December 1781 – 10 February 1868) was a Scottish scientist, inventor, author, and academic administrator. In science he is principally remembered for his experimental work in physical optics, mostly concerned with the study of the polarization of light and including the discovery of Brewster's angle.
