Working Principle
The PM-11 Microscope functions by illuminating specimens through a polarizer and focusing light using high-quality objectives. The circular stage allows rotation of the sample to observe optical properties at different orientations, with precise vernier readings. The swing-out polarizer and rotatable analyzer ring facilitate polarized light studies. The Bertrand lens allows conoscopic observation, while half and full-wave compensators measure birefringence and retardation. Coarse and fine focusing ensures sharp, high-contrast imaging. The combination of polarizing optics and precise mechanical controls allows accurate analysis of mineralogical, metallurgical, and crystalline structures.
