The importance of Microscopes. Microscopes help the scientists to study the microorganisms, the cells, the crystalline structures and the molecular structures, They are one of the most important diagnostic tools when the doctors examine the tissue samples.
Microscopes are the instruments used to view minute objects. These objects can be microorganisms, tissues or living cells, etc. There are different types of microscopes like simple, complex, electron microscope, etc.. And these microscopes are used mostly in research or disease diagnosis every day by scientists and healthcare personnel.. But let us see these uses in detail.
The microscope is used in a variety of scientific fields for many different purposes. Whether it be in forensics or traditional medical science, the microscope is an indispensable instrument.
The most common microscope (and the first to be invented) is the optical microscope, which uses light to pass through a sample to produce an image. Other major types of microscopes are the fluorescence microscope, the electron microscope (both the transmission electron microscope and the scanning electron microscope
Electron microscopy (EM) has long been used in the discovery and description of viruses. Organisms smaller than bacteria have been known to exist since the late 19th century , but the first EM visualization of a virus came only after the electron microscope was developed. Ernst Ruska, with his mentor Max Knoll, built the first electron ...

USE OF THE MICROSCOPE The microscope is absolutely essential to the microbiology lab: most microorganisms cannot be seen without the aid of a microscope, save some fungi. And, of course, there are some microbes which cannot be seen even with a microscope, unless it is an electron microscope, such as the viruses.
INTRODUCTION. Electron microscopy (EM) has long been used in the discovery and description of viruses. Organisms smaller than bacteria have been known to exist since the late 19th century (), but the first EM visualization of a virus came only after the electron microscope was developed.Ernst Ruska, with his mentor Max Knoll, built the first electron microscope in 1931 as the project for his ...
The compound microscope is a light microscope that uses light to "see" microbes. Viruses are too small. The electron microscope uses electrons to "see" microbes or viruses.
Microscopes are important because they allow scientists to study microorganisms, cells, crystalline structures and molecular structures. Microscopes are one of the most important diagnostic tools when doctors examine tissue samples. Electron microscopes help create the very tiny electrical circuits found on silicon microchips.
Compound microscopes provide several objective lenses with different levels of magnification and a light source for illuminating specimens. Compound microscopes are limited to a maximum magnification of about 2,000x the specimen's size; theoretically, they can go higher, but the human eye and brain cannot process the information.
