The Pole Piece Sampler is a microscope used to observe optical crystals and other anisotropic materials. It has some unique advantages and features compared with ordinary optical microscopes, as follows:
Polarized light source and polarizer: The pole piece sampler uses a polarized light source and polarizer to change the vibration direction of the light. By adjusting the direction of the polarizer, the transmittance and reflectivity of the light in the sample can be changed, thereby providing more information about the structure and properties of the sample. Information.
Identifying crystals: The pole piece sampler has great advantages for observing crystals, because crystals will show unique birefringence under polarized light. Through the pole piece sampler, the birefringence pattern of the crystal can be clearly observed, and the crystal type and orientation can be identified based on the birefringence pattern.
Measuring the optical properties of the sample: The pole piece sampler can be used to measure the optical properties of the sample, such as refractive index, degree of birefringence, etc. By observing and analyzing the optical properties of the sample in different polarization states, information about the structure and composition of the sample can be obtained.
Suitable for anisotropic materials: The pole piece sampler is suitable for observing anisotropic materials, including crystals, liquid crystals, fibers, etc. By adjusting the orientation of the polarizer and observing how the sample behaves in different polarization states, the anisotropic properties of the material can be revealed.
Used in geology, materials science and other fields: Pole samplers are widely used in geology, materials science, biology and other fields. They can be used to observe the microstructure and properties of rocks, minerals, fibers and other samples to help research Personnel understand the formation, properties and applications of materials.
In general, the pole piece sampler has unique advantages and characteristics in observing anisotropic materials, identifying crystals, and measuring optical properties. It is one of the important tools commonly used in scientific research and experimental analysis.
