What is the magnification of the microscope oil mirror
A microscope has an eyepiece and an objective. The eyepiece usually has a magnification of 10X, and the objective lens can generally be selected as 2X, 10X, 20X, and 40X, so the corresponding total magnification is 20X, 100X, 200X, and 400X. There are also 63X and 100X oil mirrors with higher magnification, which can magnify up to 630X and 1000X, which are expensive and the limit of optical microscopes. This is because, due to the limitation of visible light wavelength, the limit of the optical signal that can be clearly imaged by an optical convex lens is approximately 0.2 micrometers, corresponding to an amplification factor of approximately 1500X, known as the Abbe limit.
So, what about a microscope that magnifies thousands or tens of thousands of times? In fact, at this time, microscope merchants adopted digital technology, similar to optical and digital zoom in digital cameras, sacrificing resolution to enlarge images. So, you get a larger image, but the image will inevitably become blurry.
Daily use of a microscope is actually just a small hobby, there is no need to overly pursue magnification. The 400X microscope is now able to clearly see cells and simple organelles. At this point, what limits you from further observing smaller objects is not the magnification of the microscope, but your ability to prepare the sample to be observed. Buy a microscope and ask about the magnification of his eyepiece and objective lens.
The characteristics and scope of use of oil mirrors
The use of oil mirrors is the same as the ordinary method, which is to add tar when using oil mirrors.
2. The key point to note is that after using the oil lens, first wipe off the cedar oil on the lens and specimen with a small amount of xylene on the lens wiping paper, and then wipe it clean with dry lens wiping paper. Also, after adding tar, the field of view becomes noticeably darker, so it is necessary to raise the collector to the highest position and open the aperture to the maximum. Before using an oil mirror, it is necessary to first place the target observed through a low magnification lens and a high magnification lens in the center of the field of view.
