How to Choose the Best Among All Inverted Metallographic Microscopes
Both upright and inverted metallographic microscopes are equally important in metallurgy although they serve different purposes. Since upright microscopes are more commonly used than their inverted counterpart in almost all fields of science, it is understandable why many people find it more difficult shopping for the best of inverted metallographic microscopes.
A Basic Understanding of Inverted Microscopes
Before we delve into the essential features of inverted microscopes as a metallurgic device, let’s first try to review the functions of an inverted microscope.
An inverted microscope has its condenser and light source situated on top and pointing down while the turret and objectives are situated below and pointing up. In laymen terms, inverted microscopes require users to look up to a certain specimen while the more commonly used upright microscope requires users to look down.
Inverted microscopes were designed to study specimens that are either too heavy or large and those that are greatly affected by gravity. Metallurgical samples can be quite heavy, and that’s why they need the fixed and sturdy stages that inverted microscopes come equipped with. These are also used to observe living organisms or cells placed inside containers like tissue culture flasks, allowing researchers to observe the specimen in a locale more similar to their natural habitat than when observing them on glass slides, as required by upright microscopes.
The size of inverted microscopes depends primarily on its purpose. Those with routine sizes are smaller and have less fine focus as well as more limited movements and options for its stages because you’re probably dealing with just one or two types of samples for your work.
Inverted microscopes built for research are, on the other hand, bigger and more versatile. They even have connectivity ports available so you can attach them to cameras or other devices. They also have more complex features to allow you to dissect a wide selection of samples. Sometimes, the transmitted illuminator of an inverted microscope is replaced by a metalagraph to study carbon fibers.
Key Features to Look for in Inverted Metallographic Microscopes
Assuming that budget is no concern, these are the features that you should look for in inverted metallurgical microscopes to broaden and enhance the results of your studies in metallurgy.
Application – It’s tedious to use a different microscope for a different purpose so try your best to look for an all-in-one inverted metallographic microscope. For the purpose of definition, all-in-one microscopes are those capable of providing highly precise images for all modes of observation. The microscope must also be configurable to ensure that you’re studying the specimen in optimum conditions. At the very least, the microscope must allow automated live cell microscopy.
System Expandability – Look for an inverted metallographic microscope you can grow old with or one that can accompany your academic travels as it grow in scope and complexity. Your microscope should have all the necessary ports to transmit images to digital cameras, CCTV monitors, and computers. The microscope should also let you use a different and optional light source, a change of objective lenses to accommodate phase contrast microscopy (apodized or not), insert laser illumination devices, and other accessories that could improve imagery.
Precision – Getting precise results from your microscope is a matter of human control and product quality. You can definitely do something to improve the former, but you either buy the right product or not with regard to the latter. An inverted metallographic microscope is considered to provide superior precision if it has a sturdy foundation that’s immune to vibrations. If there is movement, it must be able to translate changes precisely as well. Lastly, the microscope must be resistant to temperature changes.
Optical Performance – How powerful is your inverted metallographic microscope? You’ll know the answer by checking your microscope’s resolution and numerical aperture. Can it work on objects observed in longer distances? What about field illumination?
Product Design – Although aesthetics won’t improve your results, it could make research easier and more fun when your gadgets are great to look at. They’re easier to boast of as well to your colleagues. Always look for convenience and comfort. In other words, look for an ergonomically designed microscope: are all the necessary buttons easily within reach?
Miscellaneous Details – What kind of features does the microscope offer to provide you with highly accurate samples? Are there free items offered together with your purchase like dust covers, extra bulbs, fuses, and maybe even a bottle of immersion oil? Is it 110 or 220? Is it certified by the latest from ISO? How about warranty?
Take your time choosing the best of inverted metallographic microscopes because they’re expensive and durable enough that you’ll only need to buy it once in a lifetime.
