In a metallographic microscope, certain optical components, for storage purposes, some mechanical parts such as eyepieces, objectives, photographic devices, etc., need to be stored separately, and need to be installed and disassembled when using the microscope. So what are the installation steps for the eyepiece and objective lens of a metallographic microscope? Let me introduce them below.
Installation steps for eyepiece and objective lens of metallographic microscope:
1. Installation of the eyepiece of the metallographic microscope Coke reactivity
Installing the eyepiece is relatively simple: first remove the plastic dust cover on the eyepiece tube, then insert the selected eyepiece from the upper end of the eyepiece tube. If you need to replace the eyepiece with a different magnification, simply pull out the originally installed eyepiece from the tube, and insert the eyepiece you want to use into the eyepiece tube. Be careful to ensure that the eyepiece fully aligns with the supporting surface of the eyepiece tube.
2. Installation of the objective lens of the metallographic microscope
The objective lens of a metallographic microscope is installed on the objective lens converter. When installing the objective lens, turn the coarse adjustment handwheel by hand to raise the stage, while maintaining a sufficient distance between the stage and the objective converter. Then screw the three objective lenses with different magnifications into the objective screw holes of the converter in the order of low, medium, and high power. Do not install them without order.
Before the threads are fully tightened, do not let go to prevent the objective lens from falling and being damaged, but also do not tighten too much; it should be moderately tight. After installation, rotate the converter to bring the objective lens into working position. At this point, you should hear a slight 'click' sound from the spring tip of the converter engaging with the wedge groove.
It is worth noting that when rotating the converter with the objective lens installed, use your fingers to grasp the edge of the converter to rotate it, and do not push the converter by pulling the objective lens, because this operation may easily cause the optical axis to tilt, damage the objective lens threads, and affect the coaxiality of the mechanical system and the optical system.
The above content is an introduction to the installation steps of the eyepiece and objective lens of a metallographic microscope. A metallographic microscope is mainly used for identifying and analyzing the internal structure of metals. It is an important instrument in the study of metallography, a key device for quality inspection of products in industrial sectors, mainly used to identify and analyze the structure of various metals and alloys, and is applied in factories or laboratories for quality inspection of castings, raw material testing, or research and analysis of metallographic structures after material treatment.
