What is the magnification of the oil microscope?
Many microscope vendors confuse the relationship between optical magnification and display image magnification, misleading consumers.
A microscope has an eyepiece and an objective lens. Eyepieces usually have a magnification of 10X, while objective lenses can be selected from 2X, 10X, 20X, and 40X, so the corresponding total magnification is 20X, 100X, 200X, and 400X. There are also 63X and 100X oil microscopes with higher magnification, which can magnify up to 630X and 1000X. They are expensive and are the limit of optical microscopes. This is because, due to the limitation of visible light wavelength, the limit of optical signals that can be clearly imaged by optical convex lenses is approximately 0.2 micrometers, corresponding to a magnification of approximately 1500X, known as the Abbe limit.
So, what is the so-called microscope that magnifies thousands or tens of thousands of times? In fact, at this time, microscope merchants adopted digital technology, similar to optical zoom and digital zoom of digital cameras, sacrificing resolution to enlarge images. So, you get a bigger picture, but the image will inevitably blur.
Daily use of a microscope is actually a small hobby, there is no need to excessively pursue magnification. The 400X microscope can now clearly see cells and simple organelles. At this point, what limits your further observation of smaller objects is not the magnification of the microscope, but your ability to prepare the sample to be observed. Buy a microscope and ask him about the magnification of the eyepiece and objective lens at his house.
