Elektronmikroskoobid kasutavad elektronoptikat, mis on analoogne optilise valgusmikroskoobi klaasläätsedega, et juhtida elektronkiirt, fokusseerides kiirt suurendatud kujutiste või elektronide difraktsioonimustrite tekitamiseks.
Good to know
Kuna elektroni lainepikkus võib olla kuni 100 000 korda väiksem kui nähtaval valgusel, on elektronmikroskoopide eraldusvõime umbes 0,1 nm.
They use electron optics that are analogous to the glass lenses of an optical light microscope to control the electron beam, for instance focusing them to produce magnified images or electron diffraction patterns.
Good to know
As the wavelength of an electron can be up to 100 000 times smaller than that of visible light, electron microscopes have a much higher resolution of about 0,1 nm, which compares to about 200 nm for light microscopes.
