TOGO!! togo is the country that descovered lenses and made microscopes because they thought that it will be easier to see bacteria close up as you cannot see bacteria and other organs like germs close up and they wanted to be scientific like ms potter

both are bright field microscopes, and works on two lenses
doubled lenses
The lenses in electron microscopes are typically made from electromagnets, rather than glass lenses used in light microscopes. These electromagnets focus and direct the electron beam to generate high-resolution images by controlling the path of the electrons.
Early microscopes had limitations in the quality of lenses, resulting in unclear images. These lenses were often unevenly shaped and prone to distortion, which hindered the sharpness and accuracy of the images produced. This restricted the ability of early microscopes to provide detailed and precise observations of specimens.

Simple Answer:History records that van Leeuwenhoek made about 500 lenses and used these in nearly 200 microscopes that he built which represented about 25 different microscope designs.Longer Answer:Anton van Leeuwenhoek's technical advancement was primarily that he invented a method for making small spherical lenses that much increased magnification of simple microscopes. (He did not invent the microscope.)Beyond the discovery of the methods for making small spherical lenses, van Leeuwenhoek also built microscopes and experimented with their design, addressing the difficult problems of illuminating, holding and viewing the specimens.He made over 500 optical lenses, though they did not go into 500 different microscopes. The microscopes themselves were expensive and time consuming to construct, but records indicate possibly as many as two hundred were made. In this process he is said to have created at least 25 variations on the basic design of the microscope.Only nine of his microscopes are known to exist today.

Anton van Leeuwenhoek invented a method for making small spherical lenses that much increased the magnification of simple (one lens) microscopes. The magnification of 250 times and possibly greater was ten times better than compound microscopes at the time. Beyond the initial discovery of the method for making small spherical lenses, van Leeuwenhoek built microscopes and experimented with their design and use. In the process, he made important new discoveries of microscopic life. Over a period of nearly 50 years, he made over 500 optical lenses (though they did not necessarily go into 500 different microscopes) and can be said to have constructed at least 25 variations on the basic design of the microscope. Nine of his microscopes still exist.

Modern microscopes use lenses made of glass or plastic to bend light in order to magnify images, allowing researchers to see tiny details that are not visible to the naked eye. These lenses work by refracting or bending the light that passes through them, helping to produce a clear and enlarged image of the specimen being observed.
