General information on microscopes:
With a history of more than 400 years, the microscope has become an important instrument in a variety of fields. A microscope is made up of a strong frame, onto which a viewing tube with various lenses is attached. The eyepiece (magnifying glass) makes the image visible to the naked eye. The tube is also called the viewing tube and often contains prisms or corrective lenses in addition to the eyepiece, to correct the viewing angle and other defects. Most microscopes have three to five lenses, which are used to adjust the magnification factor. This can be done by turning the disc that the lenses are attached to. To focus the image on the object, another rotary knob can be used. The object you are studying can be fixed to the glass under the viewing tube using a clamp. The light can be adjusted via the aperture, so that you can see the desired subject under different conditions. In addition, it is important to keep the working distance between the object and the bottom lens between 80 and 120 mm.
