Working Principle of Research Polarizing Microscope RPM-168
The Research Polarizing Microscope RPM-168 operates on the principle of polarized light microscopy, where plane-polarized light interacts with anisotropic materials. When polarized light passes through birefringent specimens such as minerals or crystals, the material alters the light’s vibration direction and phase.
The analyzer positioned above the objective lens combines with the polarizer below the specimen to generate interference colors, extinction patterns, and optical characteristics. By rotating the specimen on the graduated circular stage, researchers can examine crystal orientation, optical sign, birefringence, cleavage, twinning, and internal stress distribution.
The integrated Bertrand lens enables conoscopic observation for studying interference figures and optic axes, making the RPM-168 ideal for advanced mineralogical and crystallographic investigations.
