Light microscopes are small and lightweight. This is all quite hypothetical, and don't try any of this, please. If you need to see the 3-D external shape of an object with your work, then your best option will always be an electron microscope. When you have an electron microscope (especially a scanning model), then you have an equipment option which can allow you to match the pictures you see with current textbooks, online resources, and other research materials. help scientists to study microorganisms, cells, crystalline structures, and molecular structures, They are one of the most important diagnostic tools when doctors examine tissue samples. Microscopes are mechanized instruments that scientists have used to study small objects under a microscope. 8. The most frequently used lens when operating a light microscope is 10x, which can give you a final magnification of 100x when used in conjunction with a 10x ocular lens. In other words, the SEM is first used as a screening tool to detect the presence of different shapes of gold nanoparticles, including cubic, octahedral, and rhombic dodecahedral. Some cutting-edge types of light microscopy (beyond the techniques we discussed above) can produce very high-resolution images. If you were to use an electron microscope, then everything you would see would be in black and white. 9. The microscope is a device that uses lenses to make small objects appear larger. There are few disadvantages, but with time, technology will help in overcoming them. Microscopes with high resolution shed fresh light on the tiniest of details, making the hitherto unseen apparent. Light microscopes use a white light wave that is the equivalent of 0.55 microns. The most obvious disadvantage of a light microscope is that you must use it under specific conditions. A long working distance enables users to work with or handle large items, such as gems and jewelry, and a 10MP camera with a reduction lens and USB 2.0 output enable users to take and display photographs on a computer or projector.
