Click Here For Best Selection Of High Quality Polarizing Microscope

Light, as observed in optical mineralogy studies, is not polarized by cubic minerals. It has been observed in the field of optical mineralogy study that when a cubic mineral specimen is placed on a stage of polarizing microscope used, the vibration direction of light produced by the polarizer is not changed even when several minor adjustments on the stage rotation are made. It clearly demonstrates that the light that reaches the analyzer is polarized at right angles to the vibration direction of the analyzer. The light is also completely absorbed. In general, all cubic minerals as well as glass will appear black whenever evaluated in crossed-polarized light of petrographic polarizing microscopes. But is also interesting to note that this property can only be found displayed by special sections of anisotropic minerals.
