GlossaryPolarized Light Microscopy

technique using polarized light to enhance specimen contrast

Polarized Light Microscopy (PLM) is a technique that uses polarized light to examine specimens that are difficult to see with standard light microscopy. By passing light waves through polarizing filters, PLM enhances contrast and reveals details about the structure and composition of materials, such as hair fibers, minerals, and biological tissues, which can be particularly useful in diagnosing conditions like alopecia.
