How is a microscope used and what is it used for?

The microscope is perhaps the gadget that every student would need to be able to use at least once in his life. Thanks to this, samples of all kinds can be analyzed and the truth is that it opens us to a world that is undoubtedly fascinating. Let’s see below how a microscope is used and what it is used for.How is a microscope used and what it is used for? The microscope is a scientific device that allows you to magnify the image of small objects. This operation is carried out thanks to a lens. With a microscope it is possible to observe the smallest details. There are three main operations that you can perform when you have this tool in your hands: enlarge the image of a sample, separate and make the details visible. One of the main components is certainly represented by the lens, which allows us to enlarge the image. Objectives can be achromatic, especially in the case of hobbyist models, or flat in microscopes used in the biological field to examine and observe slides. Then there are other types of lenses always designed for professional use. In general, these elements are interchangeable and the magnification capacity varies. Another fundamental component of a microscope is the eyepiece, which is the part on which we rest the eye. The eyepieces can be two (binocular microscope) or also one (monocular microscope). Binocular microscopes guarantee a more comfortable observation. In these cases, attention should be paid to the value of the pupillary distance, that is, the minimum distance between the eye and the eyepiece. The advice for those who wear glasses is to take them off and use the microscope by fine-tuning the pupillary distance.Magnifications Another thing to keep in mind when using the microscope is knowing how much it magnifies. The power of the magnification is a value that is calculated when the magnification power of the eyepiece and the objective is multiplied. Having interchangeable lenses means being able to count on increasing magnification values. However, we must not forget that the higher the magnification, the greater the distortion of images can also be. Lighting Lighting is another key element in using a microscope. Light is used to better distinguish the various details in an image. The type of lighting present in the most sophisticated models is that of Kholer. In the models accessible to all, lighting is ensured thanks to an LED system.Main steps for using a microscopeOnce we know what this scientific device is for and what elements it is made of, let’s see all the steps to use it correctly: the microscope from the dust bag that wraps and protects it when not in use. Make sure the plug is properly inserted into the socket. We place the microscope on a support surface. Always better in a central position to avoid accidental falls. We turn on the microscope light (you will find it to the side). We position the sample that we intend to observe and fix it with the tweezers on the placement tray. The sample should be placed in the center so that light passes through it. We adjust the condenser so that the slide glows with the right amount of light. If no beam of light is emitted, the diaphragm is not open. We use the lens and start focusing the image. First, the eyepieces and their distance must also be adjusted.We will also need to change the targets so that we can closely observe the sample based on the magnification power of each target.
