Working Principle
The PM-11 Polarising Microscope operates by directing illumination through a swing-out polarizer to generate plane-polarized light. This light interacts with specimens mounted on the rotatable circular stage, producing orientation-dependent optical effects. The analyzer, compensators, and rotatable analyzer ring modify and evaluate the transmitted light. The Bertrand lens enables conoscopic observation, while coaxial focusing ensures accurate, high-contrast imaging during detailed polarimetric analysis.
