Microscopes are a scientists’ best friend. They help them see what misses the eye. They say the devil is in the details. That is how life threatening pathogens were discovered. With this discovery came the quest to find a cure. For small pox, for malaria, for jaundice and many other diseases.
A microscope is an essential part of a scientists’ equipment. There are various types of microscopes. There is light microscope, electron microscope, scanning probe microscope, fluorescence microscope. Each microscope has a different function and can be used in different cases.
A light microscope is the most commonly used microscope. It is called so because it uses a light source. This light source can either be the sunlight or an artificial source like LED or bulbs. In a light microscope objects are seen against a white background. For this purpose samples on the slide are usually stained in different colors to get a better image. However a major drawback for this kind of microscope is that some sample do not take in a dye and therefore they can’t be seen clearly. For this reason you can use a fluorescence microscope or a dark field microscope. An electron microscope produces the largest magnification and therefore it helps us see what even a light microscope can miss. An electron microscope uses a bombardment of electrons on the sample and the diffraction are analyzed to get an image.
Choosing the right microscope is critical. To view a button you need not use a high power light microscope. A low power light microscope will give a better picture. A high power one can give you a 400x to 1000x magnification based on the lens used.
You can find people’s opinion on various microscopes online on which material must the microscope be made of. All the information regarding cleaning and maintenance can also be found online. You can even buy one online instead of ordering from a dealer near you.
