In general, metallographic samples are obtained by embedding small cylindrical standard blocks with a diameter of 1 inch to 2 inches, or 25mm to 50mm. After grinding and polishing, they are placed under a metallographic microscope for observation. An upright metallographic microscope is sufficient. However, for some laboratories, the samples are relatively special, and the sample size for metallographic analysis is relatively large and the shape is irregular. In this case, ordinary upright metallographic microscopes are difficult to meet the observation requirements of oversized samples due to the limitations of testing distance. There are also metallographic laboratories where the types of samples are not fixed, and the size of the samples also varies, making it difficult for an upright metallographic microscope to meet the testing requirements. At this point, choosing an inverted metallographic microscope can easily solve these problems. A metallographic microscope that can observe both large and small sample sizes refers to it& Flash; Inverted metallographic microscope!


The representative inverted metallographic microscope belongs to Leica DM ILM inverted metallographic microscope from Germany. Its six major technical features make it more suitable for observation of metallography and industrial materials.

    Firstly, this inverted metallographic microscope adopts a modular design, which allows for the selection of modules according to users' observation needs. This is equivalent to customizing an optical detection system for users, making it targeted, very fast and outstanding in completing all routine daily observation and measurement tasks. High efficiency, no redundant functions, saving procurement costs.


Secondly, this inverted metallographic microscope features Leica's unique high-performance optical design, providing clear bright field reflection, polarization, and fluorescence with high resolution and contrast effects, making the imaging effect impeccable.

    Thirdly, this inverted metallographic microscope eyepiece has a special structure located below the stage, making it more suitable for observing large workpieces or samples and saving time. Especially when a series of observations and a large number of sample inspections are required, the advantages are more significant.


Fourthly, this inverted metallographic microscope is suitable for special applications, with powerful image acquisition and intelligent analysis software that can greatly meet the special observation requirements for metallographic samples.


Fifth, this inverted metallographic microscope has six types of observation lenses to choose from, including Ergotube (adjustable range from 0° to 35°) for human and engineering variable observation angles, making the observation work in front of the microscope very comfortable and making work easier.


Sixth, this inverted metallographic microscope is equipped with a built-in power control system and a 6V/35W halogen light source for easy brightness adjustment while saving experimental desktop space.

    In my personal opinion, the application of inverted metallographic microscopy is more extensive and flexible, suitable for observing various samples and meeting different testing needs. One device can hold up to two, with high cost-effectiveness. Therefore, I chose an inverted metallographic microscope, which can be observed in both large and small sample sizes, saving money and being practical.
