The Importance Of The Microscope

Microscopes have been an integral part of the medical and biological fields. They have been used for many years but were first invented in 1950’s by Zacharias Jansen and his father Hans. The microscope has greatly aided the study and creation of medicine in its field. The microscope was greatly used on the 16th and 17th centuries in mainly Italy and Holland. It was first described and suggested in 1646 by Athanasius Kircher that the microscopes may enable us to see things in the blood of fever patients. After that in 1658 he described seeing tiny microscopic worms in in plague victims, which he had suspected to cause the disease that ended up killing millions in Europe during the 17th century. This was they first clinical use of the microscope. The light microscope works very similarly to a refracting telescope except the microscope will use and gather only a small amount of light unlike the telescope, which will gather a large amount. The telescope will use all the light to focus in on a large dim object at a long distance but the microscope will have a small lens to focus on a smaller specimen. A large difference would be the condenser in the microscope, which will take the light and focus it onto a spot of the specimen being studied. This spot is the same area of what is under view of the

This microscope mainly functions like a light microscope but instead uses electrons instead of a light source when viewing the slide. This is much more accurate and clear because of the lower wavelength of electrons compared to regular light, the electrons are able to give us a resolution which is around a thousand times better than that of a light microscope. Usually a Tumor that hard to classify or diagnose is required to be sent to TEM. Small 1mm portions of the tumor are immediately prepared for TEM by being fixed in
