What is a metallographic microscope? What types of metallographic microscopes are commonly used?

    Microscopes used to study metallographic structures are called metallographic microscopes.
Unlike biological microscopes, it uses reflected light to observe opaque objects.
    Metallographic microscopeThere are many models,

Common types of metallographic microscopes include the following.

(1) Portable small metallographic microscope
    These microscopes have a simple structure and are easy to use, making them very suitable for heat treatment vehicles
It can be used for on-site inspection work in the interval, and can be observed in the exposed area.

(2) Upright metallographic microscope
This kindMicroscopeThe difference from benchtop is that when observing, the objective lens faces upward, while the surface of the object faces downward,
It also offers high accuracy and a wide range of applications, allowing observation in exposed areas,
You can also observe using dark areas.

(3) Inverted metallographic microscope / also known as horizontal (horizontal) metallographic microscope

Its structure is roughly the same as the vertical type, allowing for various lighting methods and various placements
For large multiples, higher multiples can reach 2500
