The microscope is maybe the most common equipment in any microbiology lab, since it enables students and professionals to witness organisms and structures invisibles to the naked eye. There are microscopes with some distinct magnification levels, ranging from hundreds to thousands of hundreds in diameter. Of course, the price of a microscope increases with its quality, but even the simplest microscope can furnish remarkable views of the microbiology world.
Each kind of microscope and each technique of material preparation offers some exact advantages on the demonstration of certain morphological elements. In this article series, we will learn the theory and types of microscopes, as well as some of the microbiological methods used to witness the dimensions, the shapes and structural characteristics of microorganisms.
Microscope
The microscopes fit into two categories: light (or optical) and electronic, depending on the principle or method of magnification employed. In light microscopy, the magnification is obtained through a theory of visual lenses while in electronic microscopy a bean of electrons is used to produce the enlarged image.
The light microscopy can be divided into six sub-categories:
Bright field microscopy Dark field optics Ultraviolet microscopy Fluorescence microscopy Phase incompatibility microscopy Differential interference incompatibility (D.I.C).
Beginners will much probably use absorbing field microscopy to witness their samples, since it is by far the most common technique employed in explore and capability control labs. However, it is very foremost to know the other applications, for each one has a unique asset that makes it especially desirable for the demonstration of exact morphological structures.
See you tomorrow for the next article: parts and functions of a light microscope.
