What are the uses & importance of Microscopes?
Microscopes help scientists to study microorganisms, cells, crystalline structures, and molecular structures, They are one of the most important diagnostic tools when doctors examine tissue samples.
The microscope is a laboratory instrument used to examine objects that are too small to be seen by the naked eye, Microscopy is the science of investigating small objects and structures using the microscope, Microscopic means being invisible to the eye unless aided by a microscope.
There are many types of microscopes, The most common microscope is the optical microscope, which uses lenses to refract visible light that passed through a thinly sectioned sample to produce an observable image. Other major types of microscopes are the fluorescence microscope, electron microscope (both the transmission electron microscope and the scanning electron microscope), and various types of scanning probe microscopes.
Importance of Microscopes
Microscopes have opened up a whole new dimension in science, By using Microscopes scientists were able to discover the existence of microorganisms, study the structure of cells, and see the smallest parts of plants, animals, and fungi.
Electron microscopes help create the very tiny electrical circuits found on Silicon microchips, Scanning microscopes are much more sophisticated, and they have higher magnifications than light-refracting microscopes.
Microscopic examination confirms the laboratory tests that may be positive for the disease, Technicians count the number of red blood cells infected with malaria to give the doctors an idea of how advanced the disease is in a patient.
Microscopes use simple visible light refracting lenses, Electrons, x-rays, and infrared rays, They are to detect smaller and smaller structures, Scanning electron microscopes are able to resolve viruses that are far smaller than any cell, and they enlarge the view of tiny viruses, which allows scientists to develop the vaccines and cures for infectious diseases in the humans and the animals.
Scanning electron microscopes have magnifications up to several million times to view molecules, viruses, and the nano-particles, They use corrective software to increase the magnification and the resolution of images, The computers help the nano-technologists use high-powered electron microscopes to view objects with only a few molecules thick.
Electron microscopes help prepare the small surfaces for sectioning into small slices, Microscopes enlarge the images of silicon chips to help the engineers create more efficient electronic devices, When more circuits are fitted onto a small chip, the computational power of silicon microchips increases.
Optical or light microscopes are the most commonly used and the oldest type of Microscopes, Where the light is passed through the machine and through the specimen being viewed to magnify it, They use a specialized camera to produce a film or even a digital image, The stains are used on the glass slide to make the cells or the structures more easily seen.
Electron microscopes use beams of electrons rather than light to create an image, They are used to visualize the objects such as microorganisms and crystal structures that are too small to be imaged with an optical microscope.
Probe scanning microscopes are used to create images of objects that are rather flat, They use a probe that scans the object’s surface, and then the software is used to render the results into a viewable image.
Virtual microscopy uses computer technology to convert the images on the glass slides into electronic data that has a resolution similar to that achieved with the use of an optical microscope, This technique enables the electronic transport and the storage of data from the slides, and also it allows the slides to be reviewed remotely.
Microscopes are used in viewing specimens that are relatively very small in size, they are used to view the cellular structures of organs, germs, and bacteria, They play a very important role in the laboratory for the tissues and organisms which are too small to be seen clearly with the naked eye.
All branches of biology use Microscopes especially in Molecular Biology and Histology (the study of cells), Microscopes are the backbone of studying biology, The biologists use them to view the details that cannot be seen by the naked eye such as the small parasites and small organisms which is important for the disease control research.
