How to Use an Inverted Metallurgical Microscope
Inverted metallurgical microscopes are special microscopes that are used in an industrial setup. Enrich your knowledge on what metallurgical microscopes are and how to use them by reading the article below.
Today, microscopes are rampantly being used in an industrial set up, more particularly inside a metallurgical laboratory. Metallurgy is the study of the chemical and physical behavior of metals and metallic elements, including their alloys and intermetallic compounds.
Metallurgy is a branch of materials science. Generally, what a metallurgist does is to observe and analyze a certain metal. And the fact that metals are usually big, bulky, strong, and expansive are all going to be factor when it comes to the methods and tools of observation can be used to study them.
A microscope, on the other hand, is a device that is mainly employed to view small objects and organisms. A regular microscope’s built and structure cannot accommodate a big and bulky metal. Therefore, it is very hard, if not impossible, to use microscopes to observe the composition of metals. Unless of course, a very minute part of the metal can be scratched off so that it can be studied.
But all of those problems were present before inverted metallurgical microscopes are created. Inverted metallurgical microscopes are not your everyday microscopes that stand in position with the eyepiece and the objective lenses positioned above the stage. An inverted metallurgical microscope is the exact opposite of that particular framework. The stage of the inverted metallurgical microscope is at the top and the objective lens is at the bottom part. The eye piece, usually binocular, is positioned under the objectives and are protruded at an angle for easy viewing.
With this type of construction, the stage becomes free from any obstacles. Oftentimes, the stage of an inverted metallurgical microscope is made from the toughest materials so that it can accommodate any other big and bulky material for inspection or viewing. An inverted metallurgical microscope certainly provides for the proper observation of all types of metals and bigger samples as well.
Using inverted metallurgical microscopes are basically the same as using any standard microscope. The only thing a user has to do is to be familiar with the orientation of the microscope. Here are some definite instructions on how to use an inverted metallurgical microscope.
1. Place the microscope on a flat surface. If you have to move or carry the microscope, lift it from the base using both hands. If the inverted metallurgical microscope has metal arm that connects to the eye piece, use that only for balancing the microscope as you carry it. Don’t use the arm alone to move the device with because the whole system is rather heavy.
2. Adjust the nosepiece to use the desired objective. Take note that in an inverted metallurgical microscope, the objectives are pointing upwards. The nosepiece is usually connected to the arm or the central body of the microscope. And just like using standard microscopes, select the one with the lowest resolution first and proceed to calibrate it.
3. Set your specimen over the stage. The stage of an inverted metallurgical microscope is usually on the highest position. It is created that way so that there won’t be any obstruction with any of the parts of a microscope. For as long as the stage can handle the metal, there won’t be a problem no matter how big and bulky it is going to be. Just take note that the part that is going to be viewed will be the sample’s bottom part. Orient the specimen accordingly.
4. Look through the eyepiece and adjust the focus accordingly. Adjusting the clarity and the contrast of an inverted metallurgical microscope is basically the same as that of a regular microscope. Each microscope has instructions distinct of its own when it comes to focusing and adjusting. Just follow them and you should be all set.
5. Store the microscope properly when not in use. A microscope’s number one enemy would be dusts. Don’t allow dusts to penetrate the body of the microscope. Cover the microscope with a plastic cover and if possible put it inside a cabinet so it will be protected from moisture and other hazards until its next use.
These are the steps on how to use an inverted metallurgical microscope. If you know how to use standard microscopes, it won’t be hard for you to use these types of microscopes as well. With proper practice, it can be done with not much of an effort.
