Metallurgical microscope is also called material microscope, which is mainly used to observe the structure of metal structure. It can be divided into upright metallographic microscope and inverted metallographic microscope.
The upright metallographic microscope is imaged as a positive image during observation, which brings great convenience to the user's observation and discrimination. In addition to analyzing and identifying metal samples with a height of 20-30mm, it conforms to human daily habits Therefore, it is more widely used for transparent, translucent or opaque substances. Observation targets larger than 3 microns and less than 20 microns, such as cermets, electronic chips, printed circuits, LCD substrates, films, fibers, granular objects, and the structure and traces on the surface of materials, all have good imaging results. In addition, the external camera system can be conveniently connected to a video screen and a computer for real-time and static and dynamic image observation, saving, editing, printing, and various software to perform more professional metallographic, measurement, and interactive teaching needs.
Inverted metallographic microscope uses the method of optical plane imaging to identify and analyze the structure of various metals and alloys. It is an important tool for metallographic research of metal physics. It can be widely used in factories or laboratories for casting quality and raw material inspection. The research and analysis work of metallographic organization of materials after process treatment, so as to provide intuitive analysis results, is the key equipment for the quality identification and analysis of casting, smelting, and heat treatment in mining, metallurgy, manufacturing, and mechanical processing industries.
In recent years, the microelectronics industry needs high-magnification planar microscopy technology to support chip production. Therefore, metallographic microscopes have been introduced into this field and are being continuously improved to meet the special needs of the industry. Inverted metallographic microscope, because the observation surface of the sample coincides with the surface of the table, the observation objective is located below the table, and the observation is upward. This observation form is not limited by the height of the sample. Beautiful and elegant, the base of the inverted metallographic microscope has a large support area, a low center of gravity, safety, stability and reliability. The eyepiece and support surface are inclined at 45 ° C for comfortable observation.
In addition to the standard configuration options, the inverted metallographic microscope has a direct image output function through technical upgrades, which can be easily connected to a computer for intelligent processing using application software according to process requirements. To put it simply: the upright sample is placed below, and the inverted sample is placed on top. The upright objective is down and the upside down objective is up. In other words: the inverted lens is below the stage, and the test block is placed face down on the stage. At this time, the lens is down, the test block is upside down, and the lens observes the test surface from bottom to top.
The upright lens is placed on the stage, and the test block is placed on the stage with the test surface facing up. At this time, the lens is up, the test block is set up, and the lens observes the test surface from top to bottom. After selecting a certain type of microscope based on the sample, you can basically refer to the above points when considering whether to choose an upright microscope or an inverted microscope. At the same time, you should also consider your existing sample preparation conditions, because the upright microscope The requirements for sample preparation are relatively high, while the inverted microscope is relatively low.
