Many developments laid the groundwork of the electron optics used in microscopes. One significant step was the work of Hertz in 1883 who made a cathode-ray tube with electrostatic and magnetic deflection, demonstrating manipulation of the direction of an electron beam. Others were focusing of the electrons by an axial magnetic field by Emil Wiechert in 1899, improved oxide-c… WebIn its most basic form, a microscope is simply a device that allows you to see things that are not visible to the naked eye by the use of lenses to magnify your sample. That means a magnifying glass is technically also a microscope. If you use light along with a lens, you’ve got something called an optic or light microscope.
