Summary summary
While conventional light microscopes use unpolarized white light, the type of light that is visible to the human eye and is formed of waves that vibrate in random directions, polarized light microscopy uses polarizing filters to make use of polarized light, which cannot be seen by the human eye and composes waves that vibrate in a single direction.
