Quality Features of an Inverted Metallurgical Microscope

An inverted metallurgical microscope is integral for those in the profession and business involving engineering and material sciences. If you have just started your company and are still shopping for tools and equipment, make sure you know how to identify quality features of an inverted metallurgical microscope. As inverted metallurgical microscopes can fetch as high as $1,500, it’s important for you to obtain maximum value from your purchase.

Quality Features of an Inverted Metallurgical Microscope

Handheld Design – Inverted metallurgical microscopes are manufactured to accommodate samples that are beyond the normal size. Of course, this doesn’t mean that they can’t be used for studying normal samples. They still can, and it’s better to look for one with handheld design for you to be able to use them on-site as well. As much as possible, buy something that’s lightweight as this will allow you to hold the microscope up as long as necessary.

Magnetic Stand – If your inverted metallurgical microscope has a magnetic stand, you’ll be able to mount it at any angle and against any products or components made of iron. This is especially helpful when you are inspecting the quality and workmanship of ferrous items that are too large to fit your microscope’s stage or you’re unable to take a tiny sample of. This is also good when you’re working in areas where there is no available space for you to set your microscope on.

X,Y Slideway – More computations and measurements are required from metallurgical microscopes than other types of microscopes. That’s why one of its distinguishing marks is its X,Y slideway. Without these, you’ll find it more troublesome to inspect your sample.

Polarization via Epi-Illumination – Never buy an inverted metallurgical microscope that doesn’t have polarizers included. Most metals are shiny and with may even have transparent surfaces. Thus, the light it reflects may be slightly or completely polarized. With the epi-illumination function of your microscope at work, you’ll be able to observe and inspect your samples more clearly. Among other things, polarized filters help users identify minerals and other materials.

In a microscope, epi-illumination occurs when light passes through the horizontal shaft then reaches the objective and finally the sample under observation. Upon hitting the target, light will be reflected off, returning to the microscope’s objective and finally reaching the eyepieces to make the image clear and sharp to your eye.

Objectives and Magnification – The most affordable inverted metallurgical microscopes can usually give you total magnification of 40x to 600x only. But the high end microscopes can give you up to 1000x total magnification. It is up to you to determine which option is better suited to your needs.

Always make sure that the objectives used there are achromatic to reduce chances of aberration. Secondly, try to have an expert with you when shopping in order to ascertain that the objective lenses used for the inverted metallurgical microscope are truly of the best quality. Lastly, objectives must be spring loaded to protect not only the specimens from accidental contact but to keep the objectives themselves free from incidental scratches and other types of damage.

Head – Never buy an inverted metallurgical microscope that doesn’t come with a head rotatable by 360 degrees. In the field of metallurgy, there is truly no knowing what kind of samples you’ll be asked to inspect next but the rotatable head of your microscope will at least ensure you can accommodate all types of objects. Look for diopter adjustment from your microscope as well in order to be suitable even for users wearing eyeglasses.

Filtering – Earlier on, the need for polarization has been mentioned. But having other filters would be great, too, so try looking for an inverted metallurgical microscope that would at least give you green, blue, and yellow filters.

Light Adjustment – It’s better to purchase an inverted metallurgical microscope with an iris diaphragm than one using a disc diaphragm. An iris diaphragm gives you greater light control, making it easier for you to see the sample in the best light possible.

Stage – As much as possible, look for a mechanical stage because it also gives you greater flexibility when positioning your sample.

Miscellaneous – Your purchase should at least come with a free dust cover, extra fuse and bulb, and a limited life warranty. If you’re lucky, a microscope cleaning kit might even be thrown in the bargain. Check if its voltage requirements match what you have in your laboratory or workplace. Avoid buying secondhand because microscopes are very fragile and expensive; it’s hard to find a seller who’d admit to overlooking flaws in items like these.

Now that you know how to identify quality features of an inverted metallurgical microscope, you can hit the stores and start canvassing for the best brand and model!
