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 can, optionally, be blocked with a polariser oriented at 90 degrees to the illumination. More complex microscopy techniques which ...
Walter Cox McCrone Jr. (June 9, 1916 – July 10, 2002) was an American chemist who worked extensively on applications of polarized light microscopy and is sometimes characterized as the "father of modern microscopy". [1] [2] He was also an expert in electron microscopy, crystallography, ultra-microanalysis, and particle
A 2006 study on polarized light coherence led to the development of new supports (the surfs) having contrast amplification properties for standard optical microscopy in cross-polarizer mode. [2] Made of optical layers on an opaque or transparent substrate, these supports do not modify the light polarization after reflection even if the ...

This happens typically when polarized light probes an anisotropic specimen, and when this interaction modifies the state of polarization of light. In that case, the interaction needs to be described by the Jones formalism , [ 23 ] where field and object are described by a two-component complex vector and a 2×2 complex matrix respectively.
Köhler illumination is a method of specimen illumination used for transmitted and reflected light (trans- and epi-illuminated) optical microscopy.Köhler illumination acts to generate an even illumination of the sample and ensures that an image of the illumination source (for example a halogen lamp filament) is not visible in the resulting image.
The dispersion staining is an analytical technique used in light microscopy that takes advantage of the differences in the dispersion curve of the refractive index of an unknown material relative to a standard material with a known dispersion curve to identify or characterize that unknown material. These differences become manifest as a color ...
He was one of the first to recognize that polarized light microscopy is a powerful tool, which allows the detection of structures that otherwise be obtained only with great difficulty (Wolman, 1970). In 1964, Wolman was appointed full professor and head of the Department of Pathology at the newly founded Medical School of Tel Aviv University .
