What is the difference between microscope and magnifying glass?
Both microscopes and magnifying glasses are used to help people observe images that cannot be distinguished by the human eye. From this point of view, the purpose of using the two is the same. Usually many people know the magnifying glass, and they also like to call the microscope a magnifying glass. There are still obvious differences between the two, and the following editor will give you an analysis of the differences between the two?
How a microscope works
A microscope and a magnifying glass have the same function, that is, to form a magnified image of a close-up tiny object, and the opening angle of the image to the human eye is much larger than the viewing angle of the human eye when looking at the object directly. The difference between the two is that the magnification of the magnifying glass is not high, generally 8 times to 15 times; while the visual magnification of the microscope can reach more than 1000 times.
The structure of a magnifying glass is relatively simple, generally only a set of lenses (except for some imported products), which is essentially a one-time magnification, and the multiple is a fixed gear. The principle of secondary magnification of the microscope is to first use a lens with a short focal length to turn a tiny object into a magnified real image, that is, to magnify the object horizontally several times, and then use a magnifying glass (ie, the eyepiece in the microscope) to observe this has been enlarged horizontally. once like.
Therefore, we can also understand from here that the core component in the microscope is the objective lens, that is, the component that magnifies the object for the first time, which also directly affects the imaging effect of the microscope. Therefore, the editor reminds you again, if you need to increase If the magnification is used to clearly observe the image, it is more suitable to choose a high-magnification objective lens.
