PLM 100 Series Polarized Light Microscope System

PLM100显微系统

Polarizing light microscope is a microscope used to study so-called transparent and opaque anisotropic materials. Any substance with birefringence can be clearly distinguished under a polarizing microscope. Of course, these substances can also be observed by staining, but some cannot and must use a polarizing microscope. Reflection polarizing microscope is an essential instrument for studying and identifying birefringent substances using the polarization characteristics of light.

Application

Geology, petrology, minerals, crystal structure characterization, asbestos analysis and coal analysis

Ore is a natural rock containing valuable minerals. Ore is usually collected through mining and then further processed in order to extract the required minerals. Metallic ores are usually oxides, sulfides or silicates. Polarized light microscopy can be used to characterize the crystal structure and composition of ores.

Figure 3 shows the plastic shells taken by the bright-field metallographic microscope system and the PLM100 series polarizing microscope system. Due to the mechanical force of the plastic edge, the elastic effect of light will cause stress birefringence. Ordinary bright-field metallographic microscopy This phenomenon cannot be observed by the system, but the stress distribution can be sensed and analyzed by a polarized light microscopy system.
