Working Principle
The Polarizing Microscope KCX-125 operates on the principle of polarized-light microscopy.
Light from the LED illumination system passes through the polarizer, which selects a particular polarization orientation.
The polarized light then passes through the specimen positioned on the rotating stage.
When light interacts with an anisotropic specimen, such as a birefringent mineral or crystal, its polarization state can change.
The analyzer allows suitable polarization-dependent image contrast to be observed.
When the polarizer and analyzer are arranged in crossed positions, many birefringent specimens display interference colors and extinction behavior.
By rotating the specimen stage, the observer can examine how the specimen's optical appearance changes with orientation.
The microscope can also be configured for conoscopic observation using the Bertrand lens and appropriate illumination conditions.
This allows suitable interference figures to be examined for crystallographic and mineralogical analysis.
