A microscope is a device which allows one to view something which is too small to be seen by the naked eye. Some of the items which people study with the use of a microscope include skin cells, blood cells, and even single hairs. These things are a incredibly hard to see what the bare eye, and if you want to look at them in detail it is impossible to without aid. However, by using a microscope the intricacies of these and any other object are much more clearly revealed. This kind of detail is often required in science and so those who use microscopes most in their work are often scientists of some shape or form.
You are missing a large part of the story though when you only understand what the microscope is used for. It is also interesting to consider how the technology works. Because the intricacies and technical alignments of the components in microscopes are so detailed, they can be hard to get right. Surprisingly though, the way that a microscope functions and its principles for how it works are quite easy. There is a magnifying lens situated in the microscope section that is situated near the object which you want to study. This magnifying lens creates an enlarged image of the item inside of the microscope tube by using the light which is reflected off of the specimen lens. The physics of it is kind of complex, but what happens is the image that is reflected inside the microscope tube is the actual image that is made larger so that you can get a clearer picture of what is on the actual specimen lens. Most microscopes actually contain two lenses, one at each end of the eye tube. Between them is an air separated couplet.You will find that these are normally referred to as a compound lens microscope. The real image is formed in the middle of these two lenses. The lens that is closest to your eye is the one that helps you focus on the image, while the lens that is closest to the object is the lens which helps to bring the image into focus.
Your eyes should truly be focused to infinity when you are looking at an object through a microscope correctly. If a person is using a microscope a lot and getting headaches from it or tired eyes, they really need to check in to how they are focusing the microscope because this shouldn’t happen. If it is focused correctly there should be no adverse affects to using a microscope often and for long periods at a time.
The invention of the microscope is shrouded in mystery as many have claimed to have been responsible for it but there is no real evidence to confirm any one individual. Names such as Galileo Galilei and Zacharias Janssen have been suggested but nobody knows for certain who it should be attributed to.
