Highest Magnification At The Highest Resolution With A Highly Powered Electron Microscope
The problem with magnifying an image boils down to two things: power and scale. First, will the magnifying instrument have enough power to condense reflected light and present a microscopic view of the same? Second, will such power be enough to produce a scale that is both clear and precise? These two requisites have been the problem of most microscope models throughout the centuries. Some models fail to possess the power required for the undertaking, and users are limited to a specific magnification level only. Some models were able to muster enough power to magnify the view of a specimen's surface, but the scale becomes too grainy to be studies with accuracy.
An electron microscope solves the need for both these requisites. Powered by highly charged electrons as opposed to conventional optic microscopes which are powered only by certain light sources, an electron microscope is capable of displaying images at amazing clarity even in the most magnified scales. Such a feature makes a lot of things possible:
* The texture of an object is preserved even at full magnification. This allows a closer study of the material properties of a specimen's surface.
* The physical features of the materials that make up the specimen's surface can be displayed with accuracy. Distinguishing and determining their type can be accomplished with more precision.
* The composition of the said materials can better be observed given the electron microscope's immense power.
* Subatomic levels can likewise be studied, and this will shed light on the actual make of certain materials.
An electron microscope derives its power from an electron source. Thereafter, it projects the same via a well-focused and highly concentrated beam guided by lenses and apertures unto the specimen being studied. The specimen is irradiated, and light at great degrees is reflected back to the observing eye. This gives a better view of the subject at a microscopic level.
Indeed, electron-powered microscopes emerged as solutions to the ever increasing limitations of optic microscopes. Whereas before, people were limited to viewing certain magnification, nowadays, electron makes very high magnifications at very high resolutions possible.
If you have the choice between an electron-powered microscope and the conventional variety, and if you're involved in an industry that requires meticulous precision and accuracy when it comes to empirical undertakings, then do choose the former. It may cost a little more than optical microscopes, but the benefits you will receive from the same will serve you better in the long run.
