Working Principle

 

The PM-12 Polarizing Microscope operates by transmitting light from the halogen illumination source through a graduated polarizer to generate plane-polarized light. When the specimen on the rotating stage interacts with this light, birefringence effects are produced. The sliding analyzer, compensators, and stage rotation allow evaluation of optical behavior. The adjustable condenser and precise focusing system maintain consistent illumination and image clarity during observation.
