Phase Contrast Microscopy (PCM) is an optical technique that enhances the visibility of transparent or low-contrast specimens without staining. It works by converting subtle phase differences in light waves—caused by variations in thickness or refractive index within a sample—into intensity differences that appear as contrast in the image.

This makes PCM especially useful for examining fine structural details in materials such as polymers and fibers. In materials analysis, PCM is commonly used to detect contaminants, assess surface features, and evaluate the uniformity of transparent films or coatings, providing valuable insights into quality control and failure investigations.

Stereo Microscopy, also known as stereoscopic or dissecting microscopy, provides a three-dimensional view of a specimen at relatively low magnification. It uses two separate optical paths to create depth perception, making it ideal for examining the surface features, texture, and morphology of larger or irregularly shaped materials.

In materials analysis, stereo microscopy is commonly used for inspecting fractures, identifying foreign particles, and documenting sample conditions before further testing. Its ease of use and ability to provide real-time visual assessment make it a valuable tool in both routine inspections and detailed failure analysis.
