The microscope, an essential object both in educational institutes and laboratories, has the ability to improve the observation of minute particles. Scientists have discovered a large number of concepts and have been able to visualize the world of bacteria, molecules and more thanks to this fabulous device. There are many types of microscopes, used in a wide range of fields, but they can be divided into two basic types: optical microscope. Learn more on the subject from Cleveland Clinic. Optical microscopes are the most common. All kinds of secondary education biology have seen one. Optical microscopes use a lens, usually made of plastic or quartz to view things. Compound optical microscopes using available light or a light source such as transmitter of what is being seen. There are different kinds of optical microscopes.
A monocular microscope is one that has a single site where look, the binocular has two. I not kidding when I tell you that there are trioculares microscopes. They have an eye on one side and two in the other. Another type of optical microscope is the so-called esteromicroscopio. The stereomicroscope focuses on two and sometimes three different angles to provide a three-dimensional view of the observed specimen. A feature that catches the attention in these microscopes is its ability to change the light source. Ultraviolet light and infrared on a specimen can change what we see. Another feature is to change the lens so we can expand what we see two, three or even ten times.
This requires special lenses that can be purchased separately. Electron microscope. The second class of microscope is the electron microscope. Unlike optical microscope electron microscope uses a beam of electrons to illuminate and expand objects. Although both are limited in resolution, microscopes are better at this and can extend up to two million times. Although they do not use a ray of light also, have two lenses that focus the beam of electrons even more, then passing through electrostatic and electromagnetic before touching the specimen lenses. Newer versions have USB port so that they can transmit the image directly to your computer screen. Both the electronic and optical microscopes have many uses. Microscopes are cheap and easy to transport, and can be used in fields of medical research in areas where we do not have the luxury of having electricity. They are also used in clinical operations or in conjunction with any invasive diagnostic tool. For example, a colonoscopy uses certain types of optical microscope called digital microscope to scan the colon and check polyps that may or may not be cancerous. Microscopes are usually used in the chemical industry or in applications of physics where you need to see the smallest particles. Another application of microscopes is the identification and dyeing of viruses and other tiny particles. With the best lenses and the improved procedures of electronic microscopes that come into play now, there is no doubt that scientists will use these tools to discover more things in the coming years.
