Learning Microscopes – How to find the best one?
A learning microscope is a very useful device which serves in research and study of biology and other related fields. The varied purposes that it serves have made it a most needy tool in a science lab and other such fields. The magnifying feature of this device helps in many crucial discoveries and the invention of the earth. Without the aid of this useful tool a number of science aspects would have been still a mystery.
Various types of microscope are used for varied purposes. A normal biology student would use a simple device with less magnifying power, whereas in tough researches and development like in atomic or bio researches one would need a very powerful detecting device. Almost every industry is in need of different tools based on their business purpose. It’s very vital thus to choose the perfect ones.
Are you a science lover? Do you love to learn about new and rare things? Do you want to go into the details of your objects to have a better idea about it? Then surely you need a good microscope to study its contents.
Best option for learning purpose
Fluorescence microscope with confocal laser scanning:
Mostly used for examining thin strips of samples keeping it intact. It helps to identify and study specific parts of a cell, for example a protein. An attached computer gathers all the data and gives a final 3d image of the object concerned. Its strength of expanding an object is up to 2000x. It is best suited for inspecting living cells, know its structures and to study every single component of a cell individually.
• The final output is of low resolution. Image quality is not better than what can be found in electron microscopes.
• It detects only fluorescent objects, other are not visible.
• Fluorescence can cause damage to any man-made object.
Scanning electron microscopy (SEM) –
It is used for viewing objects at high resolution. It helps to study the surface in a more precise way with the 3d effects with magnifying limits up to 50000 x. The output is very real.
• Though it has a good resolution power, but often less when compared to transmission electron microscope.
• One cannot work on living cells.
• Samples having any sort of moisture content are first to be dried and coated with a thin metal.
it’s similar to the Scanning electron microscopy only one can view wet objects without hesitation. If you want to examine the objects without being treated before examining it is the best option. Before being tested, it is dropped into liquid nitrogen so that it freezes and hold all those important contains which otherwise can be removed. It is probably the best tool to examine delicate samples which can be damaged easily.
• Limited to a specific resolution.
• Living cell is not visible as they are frozen.
• Frozen parts have the potential to hide important things.
• It is a bit costly method.
Apart from the above options, various types are also found. Microscopes can be classified on their resolution, image contrast, and ways of observing etc, so go find a perfect device that will suit your need as well as your budget.
