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. Directly transmitted ...
Light entering the prism is refracted into two rays, one of which emerges as plane-polarized light. Nicol prisms greatly facilitated the study of refraction and polarization , and were later used to investigate molecular structures and optical activity of organic compounds.
Inoué can be considered the father of the field of cytoskeleton dynamics. In the 1940s and 50s, he built the first microscope capable of imaging dynamic processes in live cells, using polarized light, and proved for the first time that the mitotic spindle is composed of aligned protein fibers. [4]
The optical microscope, also referred to as a light microscope, is a type of microscope that commonly uses visible light and a system of lenses to generate magnified images of small objects. Optical microscopes are the oldest design of microscope and were possibly invented in their present compound form in the 17th century.

In cross-polarized light on left, plane-polarized light on right. The microscope employed is usually one which is provided with a rotating stage beneath which there is a polarizer, while above the objective or eyepiece an analyzer is mounted; alternatively the stage may be fixed, and the polarizing and analyzing prisms may be capable of ...
A Wollaston prism is an optical device, invented by William Hyde Wollaston, that manipulates polarized light. It separates light into two separate linearly polarized outgoing beams with orthogonal polarization. [1] The two beams will be polarized according to the optical axis of the two right angle prisms.
1957: Marvin Minsky, a professor at MIT, invents the confocal microscope, an optical imaging technique for increasing optical resolution and contrast of a micrograph by means of using a spatial pinhole to block out-of-focus light in image formation. This technology is a predecessor to today's widely used confocal laser scanning microscope.
