Polarized Light Microscopy: Techniques and Applications

This lecture covers the principles and applications of polarized light microscopy, including the behavior of light waves, different types of polarization (circular, elliptical, plane), and the effects of polarizing filters on light. It also discusses the morphological characterization techniques using polarized light microscopy, such as observing spherulites, birefringence in specimens, and the use of sensitive tint plates to identify refractive index tensor axes. The lecture delves into the observation and analysis of various materials like high-density polyethylene, polybutylene terephthalate, isotactic polypropylene, and polyamide 6 under polarized light microscopy.
