= Electron microscope
{wiki}
An <electron microscope> forms a spatially enlarged representation of a specimen using <Electrons>, <electron lenses>, and a detector. Its appeal is access to structure too fine for an ordinary <optical microscope>, but a short <de Broglie wavelength> alone does not guarantee fine <electron microscope resolution>. Increasing <magnification> can enlarge an existing blur without revealing any additional structure.
In <transmission electron microscopy>, an <electron gun> illuminates a thin specimen; <magnetic electron lenses> form and enlarge its transmitted image on a <fluorescent screen> or detector. A <vacuum> reduces collisions with gas. Lens <electric currents> control focusing and <magnification>.<Transmission Electron Microscope (TEM) by JEOL>[JEOL, The difference between Electron Beam and Light: gun, vacuum, magnetic lenses and screen]{ref}
