Polarizing microscope has become an indispensable tool in scientific research and industrial detection because of its unique optical principle and wide application range. Today, we will deeply discuss the application scope, experience and debugging method of polarizing microscope, and introduce the PH-PG3230 polarizing microscope under Phenix Optics.
First, the scope of application of polarizing microscope
Polarizing microscope is an instrument that uses the polarization characteristics of light to study and identify substances with birefringence, which is widely used in the following fields:
Biomedical field
In organisms, many fibrin structures (such as collagen and spindle filaments during cell division) have obvious anisotropy. The arrangement of molecules in these fibers can be clearly observed by polarizing microscope. In addition, it is also used in medical analysis, such as calculus, uric acid crystal detection and the diagnosis of arthritis and other diseases.
Geology and mineral analysis
Polarizing microscope is a right-hand man for mineralogists. It can detect the polarization of various minerals and crystals and help researchers identify the optical properties of minerals. In petroleum, mining and semiconductor industries, polarizing microscope can be used for quality control and industrial analysis.
Materials science
Polarizing microscope can be used to identify various biological and abiotic materials, such as starch, pharmaceutical ingredients, fibers, liquid crystals and DNA crystals. It can distinguish isotropic and anisotropic substances, and provide an important basis for the research and development of materials.
Second, the experience of using polarizing microscope
Preparation before observation
Before using the polarizing microscope, it is necessary to ensure that all parts of the microscope are in the correct position. The vibration directions of polarizer and analyzer should be perpendicular to each other to achieve the state of "orthogonal polarization analysis". In addition, the stage should be adjusted horizontally to obtain a clear image.
Observation skill
During the observation, the optical properties of the sample in different directions can be observed by rotating the stage. For some complex samples, compensator or delay plate can be used to enhance the contrast of the image.
Maintaining
After use, turn off the light source of the microscope, reset the objective lens and eyepiece, and wipe the lens with a soft cloth. Check the optical components of the microscope regularly to ensure that they are free of dust and stains, so as to prolong the service life of the microscope.
Third, the debugging method of polarizing microscope
Light source adjustment
Turn on the light source of the microscope, and adjust the aperture and reflector to make the field of view the brightest. If the field of view is still not bright enough, you can gently pull out the eyepiece or push in the Bohr mirror to adjust the angle of the reflector.
Objective center adjustment
Install the low or medium power objective lens in place, and adjust the position of the stage so that the sample is located in the center of the objective lens. If it is necessary to replace the objective lens, rotate the stage to the lowest position before replacing it.
Focus adjustment
Turn down the coarse focusing handwheel to make the objective lens close to the sample, but do not touch it. Then slowly turn the fine focusing handwheel upward until the image is clear.
