The first concepts of a microscope are formed at school in biology classes. There, children learn in practice that with this optical device you can see small objects that cannot be seen with the naked eye. A microscope, its structure is of interest to many students. The continuation of these interesting lessons for some of them is the whole future adult life. When choosing some professions, you need to know the structure of the microscope, since it is the main tool in the work.
Microscope structure
The device of optical devices complies with the laws of optics. The structure of the microscope is based on its constituent parts. The nodes of the device in the form of a tube, eyepiece, lens, stand, table for the location of the subject of study, a illuminator with a condenser have a specific purpose.
The stand holds on itself a tube with an eyepiece, a lens. A stage is attached to the rack with a illuminator and a condenser. A illuminator is a built-in lamp or a mirror used to illuminate an object under investigation. The image is brighter with a lamp with an electric lamp. The purpose of the condenser in this system is to control the illumination, focusing the rays on the subject under study. The structure of microscopes without condensers is known; a single lens is installed in them. In practical work, it is more convenient to use optics with a movable table.
The structure of the microscope, its design directly depends on the purpose of this device. For scientific research, x-ray and electronic optical equipment is used, which has a more complex device than light devices.
The structure of a light microscope is simple. These are the most affordable optical devices; they are most widely used in practice. An eyepiece in the form of two magnifying glasses placed in a frame and a lens, which also consists of magnifying glasses tucked into a frame, are the main components of a light microscope. This whole set is inserted into the tube and attached to a tripod, in which the object stage with a mirror located under it is mounted, as well as a illuminator with a condenser.
The main principle of the light microscope is to enlarge the image of the object of study placed on the stage by passing light rays through it and then hitting them on the lens system of the lens. The eyepiece lenses, which the researcher uses in the process of studying the object, play the same role.
It should be noted that light microscopes are also not the same. The difference between them is determined by the number of optical units. Monocular, binocular or stereo microscopes with one or two optical units are distinguished.
Despite the fact that these optical devices have been used for many years, they remain incredibly popular. Every year they improve, become more accurate. The last word in the history of such useful devices as microscopes has not yet been said.
