The first concepts of a microscope are formed at school in biology lessons. There, children will learn in practice that with the help of this optical device it is possible to examine small objects that cannot be seen with the naked eye. The microscope, its structure is of interest to many schoolchildren. The continuation of these interesting lessons for some of them is the whole further adult life. When choosing some professions, it is necessary to know the structure of the microscope, as it is the main tool in the work.
The structure of the microscope
The device of optical devices complies with the laws of optics. The structure of a microscope is based on its constituent parts. Units of the device in the form of a tube, an eyepiece, a lens, a stand, a table for the location of the object of study, an illuminator with a condenser have a specific purpose.
The stand holds the tube with the eyepiece, objective. An object table with an illuminator and a condenser is attached to the stand. An illuminator is a built-in lamp or mirror that serves to illuminate the object under study. The image is brighter with an illuminator with an electric lamp. The purpose of the condenser in thisThe system consists in regulating 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 stage.
The structure of the microscope, its design directly depend 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 the light microscope is simple. These are the most accessible optical devices, they are most widely used in practice. An eyepiece in the form of two magnifying glasses placed in a frame, and an objective, which also consists of magnifying glasses tucked into a frame, are the main components of a light microscope. This entire set is inserted into a tube and attached to a tripod, in which is mounted an object table with a mirror located under it, as well as an illuminator with a condenser.
The main principle of operation of a light microscope is to enlarge the image of the object of study placed on the object table by passing light rays through it with their further contact with the lens system of the objective. The same role is played by the eyepiece lenses used by the researcher in the process of studying the object.
It should be noted that light microscopes are also not the same. The difference between them is determined by the number of optical blocks. Differmonocular, binocular or stereo microscopes with one or two optical units.
Despite the fact that these optical devices have been used for many years, they remain incredibly in demand. Every year they improve, become more accurate. The final word on the history of such useful instruments as microscopes has not yet been said.
