How many times can the microscope oil lens magnify
Many microscope merchants confuse the relationship between optical magnification and display image magnification, misleading consumers.
A microscope has eyepieces and objective lenses. The eyepiece is generally 10X magnification, and the objective lens can generally choose 2X, 10X, 20X and 40X, so the corresponding total magnification is 20X, 100X, 200X and 400X. There are 63X and 100X oil lenses with higher magnifications, which can be magnified to 630X and 1,000X, which are expensive and are the limit of optical microscopes. This is because, limited by the wavelength of visible light, the limit of optical signals that can be clearly imaged by an optical convex lens is about 0.2 microns, and the corresponding magnification is about 1,500X, which is called the Abbe limit.
So, what is the so-called microscope that magnifies thousands of times and tens of thousands of times? In fact, at this time, microscope merchants adopted digital technology, similar to the optical zoom and digital zoom of digital cameras, sacrificing resolution to enlarge pictures. So, you get a bigger picture, but the image is bound to be blurry.
Daily use of microscopes is actually just a small interest, and there is no need to pursue magnification too much. A 400X microscope can already see cells and simple organelles. At this time, it is not the magnification of the microscope that limits your further observation of smaller objects, but your ability to prepare the sample to be observed. When buying a microscope, ask about the magnification of his eyepieces and objective lenses.
