Using the Metallographic Microscope for Quality Control Procedures
The microscope, all its own, is a valuable tool for many researchers, whether they are working in the life sciences or in the engineering fields. A microscope can help life scientists look at cells and sub-cellular materials, and can help microbiologists identify and classify bacteria depending on their appearance and reactions to stains. A microscope can help engineers look at their circuit boards, perform some tweaking, and come up with finely tuned projects. A microscope can also help archaeologists as they analyze fossils or artifacts that come up during their digs.
Depending on how they are designed, microscopes can help out researchers in all these fields and more. For instance, the powerful electron microscopes can help scientists working in the life sciences as they aim to study how the interior of a cell responds to different stimuli, or how certain cellular organelles appear. Electron microscopes can also help engineers analyze the surface of certain polymers or metals, and it can help them produce even better industrial materials that are stronger or more flexible. Electron microscopy, however, entails long hours of specimen preparation, and it can be expensive.
Light microscopy is still the most inexpensive way to perform microscopy. Stereoscopic microscopes, also known as dissecting microscopes, provide relatively low power magnification for a good variety of specimens. The greatest advantage of stereoscopic microscopy is the fact that specimens do not have to be sectioned thinly in order to be examined. This can be a boon to many life scientists who work out in the field and who have no access to sectioning machines. This is also advantageous to these field scientists in that they can examine samples from the field without taking them away from the habitat or bringing them to the laboratory.
Stereoscopic microscopy also plays a big role in engineering, especially in metallurgy. Metallurgical microscopes are designed to examine metals, and they find quite wide usage in the field of industry, and even in basic research. Metallurgical microscopes, sometimes referred to as metallographic microscopes, come in many makes, sizes, and models, and prices. They are modeled differently simply because different metallurgists will have different requirements and budgetary constraints.
For instance, monocular metallographic microscopes are much cheaper than binocular metallographic microscopes, but the quality of the image produced is relatively the same. Binocular metallographic microscopes, however, have two added advantages: they have two eyepiece objectives, making viewing less strenuous and straining; and the other objective can have an eyepiece reticule, which can allow the microscope user to measure certain parts of the specimen being viewed.
The most expensive metallographic microscopes, however, will usually be the trinocular models, which contain a third hole in which to fit a digital camera. Such microscopes can be advantageous to metallurgists who need to document their findings and send them off to superiors immediately. These digital microscopes can also be advantageous to metallurgists who are working out in the field, and who need to compare the different results that they get from their field experiments or observations.
Metallographic microscopes are also widely used in industry, where they serve mainly in quality control. They are used to inspect many different devices and metals, such as computer chips, circuit boards, or wafers of semiconductors. All these devices form the foundation of many of our electronic appliances, and minuscule mistakes can translate into larger ones in the long run. Thus, metallographic microscopes need to be used regularly during a production run in order to ensure quality of the product at every step.
During quality control inspections, standards have to be met, and there are many things that have to be inspected in the metal product. For instance, circuit boards have to be inspected for scratches or missing wires, and these have to be marked out immediately and the circuit board has to be either discarded or improved. Usually, a test certificate is issued, marking the product as passing quality control inspection. Inspection, in some cases, may also entail inspection of the tensile strength of metals, their hardness, if they meet size specifications, and how they appear under the metallographic microscope.
These are only a few ways that the metallographic microscope can help you carry out your quality control procedures.

If you know what kinds of quality control procedures you want to carry out, and if you have a clear idea about how your budget should wrap around your procedural and protocol requirements, then you will be able to make a wise purchase and get a good microscope that will last you for a long time.
